As static electricity accumulates, the corresponding risk level increases, and the same applies to cranes. As a natural phenomenon, static electricity cannot be completely eliminated. However, relevant measures can be taken to reduce its hazards and ensure the safety of equipment and personnel.
In high-static environments, cranes must maintain a valid safety distance. Specifically, the minimum distance between the crane boom, lifting gear, steel wire ropes, heavy loads and power transmission lines shall not be less than the specified requirements, so as to prevent safety accidents caused by static electricity.
In hoisting operations, in the event of a broken power line or the crane boom touching a high-voltage line, the first step is to cordon off the dangerous area and warn personnel outside the vehicle not to touch the crane body.
If conditions permit, separate the boom from the power source to eliminate potential hazards. If this is not feasible, the operator must not get off the crane casually. After closing all control levers, the operator shall jump off the crane with feet kept together. After landing, keep the feet closed or move out of the dangerous area by hopping on one foot, so as to avoid electric shock caused by body conduction.
Above is the correct crane operation procedure under static electricity conditions explained by Sinoko Crane. Have you mastered it?
