In this modern era, the use of cranes has increased tremendously. No longer they are rickety and clunky machines of past. Now day’s technology has also improved its capacity, speed and strength thus it has made crane operation easier and safer. In numerous industries such as mining, construction and shipyards cranes have become an absolute necessity. As cranes are heavy machines and one wrong fault made by it can make enormous accident. Therefore crane must be operated by those workers only who are well versed in it. Crane operators should also follow its crane safety systems, rules and regulations so that they can avoid hazardous deeds. Majority of accidents are cause because of crane operators. Therefore when working with it they should be mentally and physically sound. Even they should attain all basic and common knowledge so that they can handle it with full attention and care.
Cranes are those heavy equipments that are designed by the professional engineers. These are manufactured especially for those industries where heavy loads of materials require movement. Only skilled, talented and experienced operators can handle crane. A little awareness for crane maintenance can avoid and reduce the death rates by simply following crane safety systems. Industries inhabiting cranes must take a note to keep safety on their prior issue. Crane workers must be knowledgeable about everything that is concerned with its functions and mechanics. They are also need to be aware and attentive about crane safety and maintenance. OSHA is an organization that has implemented various rules and regulations in regard of crane safety. The crane operators must go through all the safety guidelines before they are on work with crane. Moreover it is highly recommended that the operators working with crane must read all the manual guidelines and prior receive all its instructions so that they can execute it well. Even it is suggested for crane safety that all the overhead obstacles must be detached for sufficient clearance and it should be set up on level and solid surface so that the process can proceed of without any mishap.
There are several parts of cranes such as limit switches, collision avoidance, rotary limit switch and load transducer. All these devices perform various functions and helps in proper execution of crane. Therefore the crane operator must check all the devices and its functions so that on their execution they do not face any obscurity. Load cell also play a significant part when a crane is operated. It is an electronic instrument that is utilized to alter the force into electrical output or signal. This load transducer inhabits one, two or four strain gauges that help in converting the input into electrical signal or current. In recent days it is found that many types of load cells are used such as washer and button load cell, fibre optic, hydraulic and pneumatic load cell.
