Crane Safety Systems- Important aspect in many industries!

To help lift and transport heavy goods around your workshop, if you have a large warehouse space (or small in some cases) and are looking for an overhead crane, do not waste your money! You work hard for your money so to order crane that might end up costing you an arm and a leg (not literally speaking) and why waste unnecessary amounts of expenditure on a brand new made. For the crane to be manufactured and installed, you may find you also have a long lead time. At the same time, crane safety also needs to be kept in mind.

From the date of ordering, used overhead cranes are in stock and can be installed in less than one week. To fit your building of choice, most dealers can modify the span of cranes. Testing and certifying the crane for its purpose, they can then install and at the same time keeping in mind crane safety. To be tested or conform to technical lifting standards that are unique to the kind of product, all lifting equipment and crane products are required. Where a crane or hoist requires a thorough examination and proof load testing, slings and shackles require only confirming to testing regulations.

To production lines and factory floors where loads up to five tonnes need to be lifted and moved in close proximity, used Jib Cranes are an advantage, as for precise hoisting and lowering of the load, a jib crane is usually floor standing featuring an electric chain hoist. To load heavy items into a lathe or to pick up heavy components in a production line, jib cranes are mostly used. With a used crane system, used electric hoists are often complete. It the device used for hoisting and handling of the load and they run along the crane beam. For applications where the operator is remote from the crane, this is usually controlled by a wired pendant control or radio remote, this can be for safety reasons or personal preference.

Making the necessary modifications to the crane bridge and reassembling after ensuring that no poor quality welds have been made and that the crane is fit for purpose, when modifying an overhead crane the dealer will remove the hoist and end carriages from the gantry. The hoist is wired up to the control box and the end carriages are then bolted back on. The crane is now ready for install, once this process is complete (if required). Load cells are also very important in a crane for the safety point of view. There are a certain amount of factors for consideration, when installing an overhead crane. This will help to keep everyone safe at a job site.

Most common crane accidents and tips to avoid them

The Operating cranes and other lifting equipment has particularly become a very common practice in many industrial contexts as electronic cranes are widely used in various construction and factory sites throughout the world. The increased volume of the traffic, of the surface of the working areas and of the amount of the loads in order to profit from the economies of scale means that these handling machines deal with the several hundred of the weights every day. With an increasing use of the cranes, comes an ever higher number of the probable crane accidents, that in the best scenario result in production delays and in the worst ones lead to the loss of the precious human lives.

The various researches, surveys and recent studies show that the main cause for the crane accidents during crane operation is lack of stability. This can be caused for a number of reasons such as the surface where the crane is particularly positioned not being uniform, the load to be lifted is exceeding the weight or size of the crane is actually able to handle, or the cranes hoist not being positioned at the gravity centre of the load. For measuring the crane’s load maximum load capacity, a crane limit switch is being inserted in all modern electronic cranes that are being manufactured in recent times.
Incidents that result in the loss of the precious human lives while operating the heavy handling machinery are in the majority of the cases due to cases of electrocution. The proper installation and dismantling of the cranes parts are also a frequent cause for these tragic events, as are crane components falling because of the faulty set up procedures.

In the particular case of the quays and the commercial ports, the accidents related to the crane operation in container terminals represent as much as 30% of the entire asset costs. The most common cause of asset damage in such contexts is the impact between the booms and the ships from which the loads are taken. Other frequent problems are related to the hoists, ropes, chains and the spreaders which not being at their best condition and to defective communication systems between the employees.

Lifting procedures do in fact involve the several professional profiles among which the supervisor, the driver or the operator of the crane and the people responsible for crane and load position warning signals. It is particularly indispensable that these people receive the proper training and the certifications before ever entering the load handling site, as well as an efficient communication method that allows them to exchange the required information and the warnings while avoiding the coordination problems between the equipment, the people and the surrounding area. The rotary limit switches are also one of the major components of the electronic cranes to avoid unfortunate crane accidents.

Various kinds of Crane scales and their uses

With the passing time and the constant changes in the modern technology, all types of the weighing equipment have come particularly a long way from the original, see saw type of weighing. ten years ago, a crane scale would have been similar to a large dial type scale which is full of springs and levers. Modern weighing equipment particularly consists of the latest, cutting edge materials and the microchip processors. At the heart of any electronic crane scale is a crane load cell. This is basically a block of the alloy or steel which draws the required power from the circuit board and, in return, gives a mill volt signal which is particularly processed and gives an accurate reading to the display. The Crane scales are very strategically engineered for all the types of industrial applications and can be readily found in all types of the factories and industrial applications today.

The outer shell is generally constructed from the industrial grade steel or the heavy duty aluminium, which provides very good durability and ultimate protection to the electronic crane scale. The outer shell construction very particularly depends on the capacity of the weighing scale and also its various applications. The small capacity scales for the general industrial use are primarily prepared from the aluminium, the high capacity scales tend to be made from a more heavy duty, steel construction.

The electronic Crane scales are also particularly found in many industrial foundries and are readily supplied with a heat guard to deflect the heat and to protect the scale. As with most of the weighing scales, the two major types of the display are used. The LCD (liquid crystal display) which is very easy to read in the direct sun light and ideal for outdoor use or LED (light emitting diode) are used for the indoors. The LCD displays come with a built in back light for the convenience of use. The power is supplied via an internal rechargeable battery, with today's technology which can give from 10 to 60 hours minimum battery life when continuously working. The LCD display crane scales draw the far less power from the batter and give a greater working life before the need for its next charge. Most of the crane scales have an auto shut function to help conserve on the power.

The modern electronic crane scales offer many excellent features to allow the user to achieve the good dynamic weighing performance, not subjected to the influence of swaying, a built in filter enables the user to adjust the stability depending on the particular application. You are also able to switch the display from kg's to Lbs and also hold the display on a particular weight. There are various capacities and resolutions to choose from. The position sensing is another great feature of the electronic cranes.

Process of operating the Overhead Cranes safely

Their toil would have been greatly eased if only they had the fair advantage of the modern technology. Although, how they are accomplished the particularly unbelievable task and certainly remains a mystery; the modern construction industry has a particularly straightforward solution to it in the form of an overhead crane which is a specialized crane particularly designed to lift the heavy material very efficiently and also safely. The crane limit switch is an integral part of the overall overhead crane safety and the security program of any industry to maintain the level of the required efficiency of its manufacturing as well as the maintenance operations.

The Overhead cranes have a particularly simplified design and a unique structure with a railed bridge and a hoist, the part which actually lifts the heavy loads and also runs across the bridge in an efficient manner. The Overhead cranes are primarily used to efficiently and conveniently handle the heavy material in the manufacturing and the transport industries. They have the applications in a wide range of the various industries including the booming steel industry, automobile industry, and the paper mills as well. Using them usually turns out to be more economical as they make the use of the mobile cranes non-essential. There are many types of the overhead cranes. Thus, the overhead crane safety is of prime importance. Some commonly used examples are the bridge cranes, the gantry cranes, container cranes, jib cranes, etc. Commonly these cranes are operated with the radio controls. However those cranes that use very heavy loads or operate at a high speed and are normally cabin controlled.

It is very important that utmost care be taken while operating these weight-lifters. An incorrect or careless handling can lead to very serious accidents and cause damage not only to property but also to human life in a big way. And therefore it is very important to follow the safety guidelines for operating the overhead cranes. It is also essential for the crane operators as well as the inspectors to undergo extensive and rigorous training before joining this particular profession. Basically, an overhead crane is very strategically designed to handle a certain amount of weight very securely. Anything beyond that is inviting trouble for sure. Therefore it should never be forced to perform beyond its safety limits to maintain the proper balance or the collision avoidance. The cranes bridge component should clearly and particularly indicate the load limits of the crane. The load limiter is an important component of the crane operations. There should be an arrangement to make some signal or sound like the sirens, etc. before every attempt of lifting the heavy loads. Utmost care should also be taken while moving a load as doing so too hastily or quickly can cause the imbalance and the crane may lean or sway resulting in the losing control of the heavy load it is carrying.

How to Operate the Overhead Crane Safely

Overhead cranes are the machines that are used in most industries for carrying very heavy loads from one place to another. These machines are very efficient and built in a way that makes them an excellent choice for handling those time consuming and monotonous jobs of lifting loads. Since these cannot be done by using manual labor, an overhead crane becomes an indispensible part of modern industrial work environment. Overhead cranes are prone to accidents and cause heavy damage to property and life and therefore it is imperative that proper overhead crane safety is followed while working with these machines.

To eliminate the risk of these accidents to some extent it is important to give proper training to the overhead crane operators. A well-trained crane operator can handle emergencies in a much efficient way. And this certainly has brought the number of accidents down in the industries related to cranes lifting heavy material.

Crane operators should diligently follow many other guidelines for the safety of their own life and the machines themselves. One of the most important one is to always undergo a complete check-up of the machinery before using them to lift heavy loads. They should be thoroughly inspected for leaks, cracks or corrosions. They should be repaired immediately if found to be having any problems and even smallest of hitches in their workings should never be ignored or discarded as being unimportant as even those can turn out be very costly and cause damage beyond consideration.

One thing has been found time and again that it is due to lack of any proper guiding system that the crane operators fall vulnerable to these accidents. If there was some kind of a signalling system in place, most of these accidents could have been avoided from happening altogether.

A load limiter is a sophisticated device that keeps check on the amount of load put on an overhead crane by indicating as soon as it is in excess and stopping the operation immediately when that happens. This prevents the possibility of an operating loading the overhead crane beyond its maximum capacity and thus is very useful in preventing any mishaps from occurring while load transfer is taking place in an industry. There are many other types of devices manufactured these days for the safety of crane operators.

Collision avoidance is also an important part of the overall safeguard system in these crane operations and can be achieved with the help of effective equipments and some safety precautions on the part of the operating workers. It is never too late to learn the safety measures and it should become an integral part of the overall training of the concerned workers and supervisors in any industry.

Top Reasons behind Overhead Crane Accidents and How to Avoid Them

Overhead crane accidents are common occurrences and the reasons behind them are not so hidden anymore. Research has shown that these accidents happen primarily due to a lack of warning about the crossing of the load limits of the cranes. This tips the balance of the cranes and causes them to either collapse or break-down dropping the heavy load they are carrying to the grounds. Sophisticated devices including crane load cell or electronic crane scale have been devised to overcome this problem to quite some extent.

So what do these ultra-modern devices do? They basically have the main responsibility to check the load being carried by the overhead cranes and measure it in order to decide if it is not beyond the capacity of the crane. Many types of safety systems have been prepared for safeguarding the interest of crane operators. A crane load cell is one of the most commonly used equipment. It has a sophisticated system in place called position sensing that accurately senses and offers exact data about the weight and positioning of the load being carried.

The various kinds of load cells being used in the industry are compression load cells, beam load cells, tension load cells, etc. There is another kind of device used to provide the crane operator precise data of the angle of the boom in an overhead crane. These types of sensors are called angles sensors and they have a digital encoder that accurately provides the information about the extent and position of the load being carried by the overhead crane.

Besides these equipments there is also a human factor involved that can be very crucial in the overall safety and security of the overhead crane functioning and thereby safeguarding the welfare of the industrial labourers, supervisors and inspectors alike. This factor is the education and training that is required to be imparted to the workers who come in direct contact with these heavy duty machineries on a daily basis.

Many times, lack of knowledge of the various precautionary measures to be taken and also about what to do if an emergency arises is the main culprit behind these workers’ panicking in such situations. If proper training is provided about the safety measures before and after a mishap and the importance of checking and rechecking the equipments every single time they are to be used for carrying massive loads, most of these unfortunate incidents can be completely avoided.

Machines are created, used and operated by living human beings. If they are to function well and in a safe and trouble-free manner then it is the responsibility of the people engaged in those operations to be well-informed about the workings and handling of these machines. This is the only way to make them keep working for a long time and in a safe manner.

An Overview of the Overhead Cranes and their Safety

Cranes are an integral part of modern industrial units that need machines to life very heavy loads and carry them from one place to another. Various industries make use of these load carriers for their unique individual purposes. These industries are prone to crane accidents if not operated with care and caution. Since they deal with very massive loads, even a small imbalance in them can cause them break and this can result in heavy damage to property and life.

Although the primary function of any crane is to lift and carry heavy burdens without the use of manual labor, there are distinct types of cranes used for different purposes. These different cranes have differing structures and designs. They also vary in their capacity of lifting weights and where and how they are used. Every crane is not suitable for every purpose and therefore they are designed to suit their exact function in a particular industry.

Three basic types of cranes are used according to the particular type of requirements in the industry. These three types are overhead cranes, mobile cranes and stationary cranes. These cranes are used in various places such as in industries, transportation, construction, harbors and ports, etc.

The overhead cranes are used in various industries such as the manufacturing, transport, steel, paper, etc. These cranes are also called bridge cranes. The three main parts of these cranes are a bridge, a runway and a hoist. As the name suggests, these cranes travel overhead along a horizontal path.

These cranes need to be handled by skilled laborers or else they have a tendency to falter and break-down under the massive pressure of the burdens put on them. Although the overhead cranes are sturdily built and have a capability of carrying enormous loads beyond any human capacity, they should not be overused or overworked under the faulty impression of being more efficient or faster.

There are many sophisticated equipments nowadays in the safety bag of a trained industrial worker. Most of the unfortunate crane accidents can be avoided using such devices as crane limit switch or rotary limit switches. There are many types of devices including the load cells such as compression load cells, beam load cells, tension load cells, etc. Other devices used are electronic crane scale, load momentum indicator, load monitors, wind speed indicators, boom angle indicators, etc.

The overhead crane operators have a range of devices available to help them maintain high security standards under the demanding material handling conditions such as carrying hefty loads using overhead cranes. It is vitally important though that the overhead crane operator is knowledgeable about the workings and operations of these devices in particular as well as the overall safety measures regarding the overhead cranes in general. This can go a long way in keeping the industrial environment safe and trouble free.

How to Benefit from the Advanced Crane Safety Systems

Crane safety is one issue that is at the heart of the overall safety issues in any industry using heavy material handling. Various industries including the construction, manufacturing and transportation industries use various types of cranes in the various industrial operations involving lifting and carrying massive loads from one place to another. This involves fair amount of risk as the cranes are machines and can never be totally safe to work with without taking proper precautions and using the various modern safety devices.

Although there are no foolproof methods to completely eliminate the malfunctioning of a machine like the overhead crane which is constantly put to a great amount of stress under the massive loads carried over them, there are many things that need to be remembered when dealing with them so as to make the operations safe and sound. Using crane safety systems is one of the most important measures of making sure that the crane operator is constantly informed about the ongoing operation and the condition of the crane under the heavy load that is being lifted or carried by it.

Crane accidents occur mostly because of the unawareness of the operator about the capacity of the crane. In the fit of over-enthusiasm or under the false impression of being more efficient, many times the crane operators tend to overload the crane with materials beyond it normal capacity. This puts an excessive strain on the equipment causing it to go off-balance and even breaking down under extreme pressure.

The only two obvious ways to deal with such a scenario are to use some form of safety systems and to educated and train the crane operators. Safety devices come under many different forms. There are many types of load cells that are commonly used for sensing and monitoring the load of the materials on a crane and give precise data. Some commonly used types are compression load cells, beam load cells, tension load cells, etc.

There are many other types of equipment used to make the crane operations safer including an electronic crane scale, crane limit switch or rotary limit switches. They have been designed to monitor the smallest of crane activities with great accuracy. They can monitor even very subtle changes and variations in the functioning of a crane operation and promptly warn the crane operator or crane inspector about it.

This makes it possible for the operator to immediately respond to the situation in an effective manner avoiding any further damage to the machinery or the material being carried. They can either halt the operation altogether or can reduce the load on the crane if that is the cause behind the crane imbalance. Only a well-trained worker is capable of handling these sophisticated machines.

Crane accidents are often described as surprising and unwanted activities

The four aspects that play most in many Collision Avoidance are equipment failing, crane owner actions, inadequate road servicing, and road design. In fact the leading majority of crane accidents are due to a mixture of car owner actions along with the other three aspects. Poor ability to drive and routines can make any situation almost impossible.
Speed is also another major aspect in many injuries. The circumstances of the street may not be appropriate for driving above certain rates of speed and boosting significantly improves your possibilities of colliding with another crane, dropping control, and failing. Always create sure your windows wipers are consistently changed to create sure your exposure is maximum under any serious varying climate circumstances.
Crane accidents are often described as surprising and unwanted activities, or an surprising accident relevant to your vehicle automobile. However, we do have some energy and management in ending car injuries because most can be prevented and circumvented using the following guidelines. If you always maintain your crane, keep your braking system and wheels up to par can significantly improve your ability to control the crane under urgent turning and avoiding conditions.

Crane Scales will only perform on fill appropriate to its potential

While working an Overhead Crane Safety, the appropriate protection choices can help you prevent expensive accidents and life-threatening problems. Before you begin to use the bridge crane, study the managing guide thoroughly as each crane has its individual requirements.
While managing, create sure that the crane can bring the plenty resolved on it. It is not recommended that you power the crane to bring plenty bulkier than its potential. You should always keep in mind that the Crane Scales will only perform on fill appropriate to its potential.
Perform with a associate. It will be better if the owner of the crane has someone that will help the function and offer the guidelines by providing out alerts. Having many individuals providing out guidelines will create it more complex. It will be better that there is only one individual who will act as your signaling individual. Ensure that that your job friend understands and conscious of the task.
A percolate stage on the platform of the boom is a easy process for making sure the crane is stage. When creating raise with a Boom Crane always use a fill data so you know the bodyweight capabilities for all the raising perspectives. Every Boom Crane has its own fill data. One duplicate is connected to the crane and one duplicate is organized by the manager.
Cranes are undoubtedly beneficial in the office. They can raise huge of weight and make tasks faster and more effective. However, because of their tremendous energy they are also incredibly risky. If a fill falls there is almost no way to quit it or notify other employees to get out of the say.

Best Ways of Dealing with Overhead Crane Safety

Overhead cranes are an integral part of the modern industrial operations. They are used to life massive loads that cannot be done manually or by any other machines. These cranes are designed to perform safely in the most demanding circumstances and care is taken to design them in a way to make them as safe as possible for the laborers who operate them on a regular basis. Any negligence in the safety measures can prove costly to property as well as human lives. Therefore, overhead crane safety occupies a very important position in the overall operational activities of any industry that uses their services.

These cranes find their most wide-spread use in the transportation and manufacturing industries besides many others. Overhead cranes are simple in structure and built in such as way that they are safe and easy to use and handle. They are composed of two main parts namely a railed bridge and the hoist.

Safety of the overhead cranes is a major issue as not only valuable equipment but also the human lives in the form of the machine operators and inspectors are dependent on it. Overhead cranes can bear a certain amount of load and if that limit is exceeded inadvertently it can cause the crane to lose its balance or breakdown altogether. Therefore it is imperative to take care not to cross these limits under the name of efficiency or faster work. Inability to know the amount of weight being lifted can be a major factor behind overhead crane accidents. In the name of efficiency and getting the work done rapidly, an operator often tends to overestimate the weight lifting capacities of an overhead crane. This can spell disaster not only to the equipment and property but also to those who are operating or supervising the machines.

Regular checking of the various components of the machines needs to be an integral part of the safety routine. Another major issue regarding the security of the overhead cranes is the possibility of collisions between cranes and other machines, buildings, objects or products that are being transported over the crane. These collisions can prove very costly and protecting the cranes from them becomes an important part of the safety measures. A Collision Avoidance system offers the much needed protection to the crane and save innocent lives.

Effective anti-collision systems possess a number of failsafe features. In case of a power-failure the interfaced motors are immediately made inactive. They incorporate self-diagnostic functions in order to monitor the system. These systems are widely used a number of industries where there are very high value and unstable loads to deal with. Collision avoidance systems are use microwave technology which makes it suitable for certain environments like harbors or steel industries. These operate as stand-alone units and are extremely accurate in their performance. They are used both indoors as well as outdoors.

Using Crane Safety Systems as a Safeguard Against Crane Accidents

Using cranes is not a new phenomenon. People have been using these equipments from a very long time to lift massive loads that are beyond the strength and capacity of manual labor or any other type of machinery. These cranes have been of different types and designs and they have been modified from time to time to suit the needs of the changing demands of the various industries. The extensive use of Overhead Crane Safety is a relatively new occurrence which has been triggered due to the various unfortunate incidences around the globe regarding crane operations.

In spite of the care that has always been taken by the overhead crane manufacturers to make their equipments the safest and most convenient for the operators, there have been accidents from time to time. Although many of these mishaps could well have been due to the human errors made by the crane operators, it has also been acknowledged that another hidden factor has been instrumental in bringing these misfortunes that not only damaged valuable property and machinery but also robbed away the lives of many innocent crane operators and other technicians who happened to be in the vicinity.

This led to more research into the possible causes and the ways to prevent these accidents from happening which led to the evolution of the various crane safety systems that are used widely nowadays. These are proving to be a great boon to the crane operators and also to the overall efficiency and growth of the industries. After all, a safe and secure environment is one of the most important components affecting the productivity of the employees and laborers in any industry or organization.

There are many types of overhead crane safety systems used to ensure that the crane operator is properly and promptly informed about anything going wrong in the equipment he is working with. These are indicators that closely monitor different variables about the operations of an overhead crane such as the weight of the load or the angle of the boom etc. and alert the operator about any changes sensed and registered by them. This makes it easy for the operator to take immediate and proper action to avoid any possible calamity.

Crane load cell is one such device that comes in various types including tension load cells, compression load cells, beam load cells, etc. Besides these load monitors, electronic crane scale, load momentum indicator, wind speed indicators, boom angle indicators etc. are some other devices used for overhead crane safety.

The training of the crane operators cannot be overlooked. Afterall, they are the ones who operate and use the cranes as well as the above mentioned sophisticated devices. This is where extensive training of the operators regarding the safe practices of using their equipments is vitally important. This way they are able to steer clear of any untoward incidents that can take place due to ignorance and carelessness.

Avoiding Overhead Crane Safety must be ensured!

With a hoisting system which glides atop a fixed overhead runway, an overhead crane is a crane having a movable bridge. It is not a child’s play to operate an overhead crane. Capable of moving enormous weight and heavy objects from one place to another, these cranes are robust machines.

If the operator doesn't know the proper safety options on bridge cranes, even a second's inattentiveness or carelessness can lead to gruesome accidents. Contractors must ensure Overhead Crane Safety to avoid such incidents.

Additionally, the safety of overhead cranes, there are vital maintenance procedures which play a crucial role in ensuring. While operating these monstrous machines, it is therefore imperative to be very careful and operators must follow all safety procedures correctly.

While operating the crane, following safety options must be followed-

The correct safety options can help you avert costly injuries and life-threatening disabilities, while working an overhead crane. Read the operating manual thoroughly as each crane has its individual specifications, before you begin to use the bridge crane. Even then, during use of any overhead crane, there are certain general procedures applicable. • While operating or working near overhead cranes, wear personal protective gear and head protective gear. • To clear any obstructions below, before moving the load, always ensure that you have a clear line of visibility all around and lift the load high enough. • The load is to be moved and never allow anybody to ride the load or the hook, warn colleagues beforehand so they clear out the area over. • Without sudden jerks in any direction, move the load as smoothly as possible. Position the hoist directly above the load before lifting it and lower it directly below the hoist, to lift load vertically and gently. To ensure a smooth movement, always keep two complete wraps of ropes on the hoist. • Except for emergency stop signals; which can come from any direction, respond to signals only from the personnel operating the lift. • The lifting capacity of your overhead crane must never be exceeded. By lifting the load a few inches off the ground before lifting it further, always test for balance.

Another vital area about which most of us become complacent over time is maintenance. In terms of time, money and health, this can be a fatal mistake which can cost you.

Every time you think of using your overhead crane, thorough inspections are a must. To check for any loose ends or hanging components, take a quick look at the outside of the machine.

For any abnormal sounds or movements from the hoist, bridge or trolley, start the crane and check. In consistence with the control buttons, ensure that the hoist is moving smoothly in all directions. Moreover, while inspecting the crane, always wear standard harness and protective clothing.
