Wire rope electric hoist is a kind of special lifting equipment, installed on cranes and gantry cranes. It has the characteristics of small size, light weight, simple operation and convenient use. It is widely used in industrial and mining enterprises, storage, docks and other places. Wire rope electric hoists may have some safety hazards during use. Understanding these potential hazards can prevent accidents.
There is no safety gear at the end of the traveling rail of the wire rope electric hoist crane. The rail end stop device should be firm and reliable to prevent the crane from derailing.
The protective shell of the electric wire rope hoist crane motor falls off. During normal work or maintenance, in order to prevent foreign objects from entering or the operation of the electric hoist crane from parts that may cause danger to personnel, protection devices should be provided. The moving parts exposed on the crane that may hurt people, such as open gears, couplings, transmission shafts, sprockets, chains, transmission belts, pulleys, etc., should be equipped with protective covers/rails.
The wire rope electric hoist raises the limit control line to disconnect and the limit fails. The lifting mechanism shall be equipped with lifting height limiter. When the retrieval device rises to the upper limit position specified in the design, it should be able to immediately cut off the lifting power source.
The electric hoist trolley forms a limit damage and fails. , Cranes and lifting trolleys should be equipped with a travel limiter in each direction of travel. When the limit position specified by the design is reached, the power source in the forward direction is automatically cut off.
The end of the wire rope electric hoist has no travel limit and no safety gear. Cranes and lifting trolleys shall be equipped with a travel limiter in each direction of travel, and automatically cut off the power source in the forward direction when the limit position specified by the design is reached.
