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.
