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.
