How to operate the crane correctly under static electricity?
With the increase of static electricity, the danger will be higher and higher, and the same is true for cranes. As static electricity as a natural phenomenon, it is impossible to completely avoid it, but at least it can be harmed by corresponding measures to ensure the safety of equipment and personnel.
When there is a lot of static electricity in the environment, the crane must maintain an effective safe distance, that is, the small distance between the boom, spreader, wire rope and heavy objects and the transmission line should not be less than the specified requirements to prevent static electricity. Lead to dangerous accidents. In the process of hoisting operation, in case the wire is broken or the boom touches the high-voltage line, the first thing to do is to enclose the dangerous area and warn people outside the car not to touch the car body.
After that, if the boom is disconnected from the power source, it can eliminate the danger; if this is not possible, the operator must not easily get off the ground. After closing all the control levers, the operator should jump off the car with his feet together, and continue to keep his feet together after jumping. Or jump out of the danger zone with one foot, this is to avoid electrical shock caused by the body's conduction.
