The driver shall not leave the post when the lifted object does not completely fall on the ground. When resting or suspending operations, objects or lifting cages must be lowered to the ground. After work, cut off the power supply and close the switch box. The driver shall pay attention to the operating conditions and the wear of wire rope at any time. When the load changes and is lifted for the first time, stop for 0.5m above the ground, and continue to rise when there is no problem.
