If any abnormal situation occurs with the wire rope electric hoist, it should be promptly eliminated before use. Wire rope electric hoists are strictly prohibited from being overloaded. When lifting near the rated load and skeletal muscle objects, there should be a weight basis or estimation. When tilting lifting is not possible, it is advisable to press the button first to tighten the steel wire rope before lifting.

　　The limit device of the wire rope electric hoist is a safety device to prevent accidents caused by lifting or lowering the hook beyond the limit position, and should not be used frequently as a travel switch. Do not dismantle it.

　　The buffers or baffles at both ends of the I-beam track are only used for limiting the position in case of accidents, and should not be collided frequently during normal operations. It is not advisable to use an electric hoist to hang heavy objects in the air for a long time to prevent permanent deformation of the other parts. If the electric hoist encounters button failure, contactor contact adhesion, etc. during use, the power should be immediately cut off
