Numerous enterprises in the manufacturing and construction sectors are heavily dependent on overhead crane systems to complete their projects. The overhead cranes are being said to be perfect for lifting and transporting construction materials. When fitted and utilized correctly, the crane systems turn the entire projects easier and safer for both worker and operator. But, it can cause severe damages and loss of life every so often lacking proper and inaccurate operation. To stop these tragedies calls for the utmost accuracy and proper safety measures that can ensure no hazard at the workplaces.
There are several threats, which can take place at any time, if the machine has not been operated properly. Numerous accidents are caused due to big lift systems such as tower cranes and mobile cranes. But threats do happen to all kinds of cranes—together with overhead cranes—and in all aspects of crane procedure. Study of overhead crane mishaps discloses three common safety threats, which all the companies involved in construction and transportation businesses should be aware of. It is highly important for each and every professional to be aware of the potential threats and the safety measures to keep them away.
Electrical Threats:
According to a data released by OSHA, about 50% of total accidents are caused by electrical hazards. Power line contact generally takes place when the machine is lifting construction materials nearby or with the help of energized power lines and the pulley line or boom touches one of them. Power line contact is factually defined as the involuntary interaction of any metallic part of the crane with a high-voltage power line. And it happens because the safety measures have not been administered properly.
OSHA suggests using non-conductive, pneumatic or radio remote control system that can not cause the accidents. In addition, the load moment indicator should also be highly prompt to display if the loads exceed the proposed extent.
Overloading:
In addition, overloading has also been very striking thing that cause deadly accidents at workplaces. Overloading over and over again takes place when ill-trained workers are permitted to handle cranes. Operators incorrectly are certain of their ability to handle the crane machine. But, it is important for operators to know the exact information on load. For such situations, crane operator finds load moment indicator very important.
Material falling:
Material falling is another threat that can cause severe accident at the workplace. In course of moving materials, it may take place, if the operation is not handled properly. Visual damage, two-blocking, sliding, mechanical miscarriage, or operator incompetency can all cause in serious injuries or fatalities at the workplace. If the supplies are not correctly protected, the materials can slide and land on labors in the locality or cause major injury to property and the workers.
Workers employed around overhead cranes are always required to use proper protection tools such as helmet, foot, hand, and eye guard. The crane operator and any employees working around the crane machine must also be alert at all time.
