Understand the common safety hazards of electric hoist
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, warehouses, docks and other places. In the use of electric hoist, various safety hazards may occur, and understanding these safety hazards can prevent them before they happen.
The protective shell of the electric hoist motor falls off: during normal work or maintenance, in order to prevent foreign objects from entering or prevent the parts that may be dangerous to the personnel from the operation of the electric hoist, a protective device should be provided. The moving parts that are exposed on the electric hoist and may hurt people should be equipped with a protective cover.
The electric hoist lifting limit control line is disconnected, and the limit is invalid: the lifting mechanism should be equipped with a lifting height limiter. When the lifting device rises to the upper limit position specified by the design, the lifting power should be immediately cut off source.
The end of the electric hoist has no travel limit and no safety gear: cranes and hoisting trolleys should be equipped with travel travel limiters in each travel direction, and automatically cut off the power source in the forward direction when the limit position specified by the design is reached.
To understand the common safety hazards of electric hoists, the purpose is to remind the practitioners to strictly install relevant safety technical standards during the work process to do a good job in the investigation and control of daily hidden hazards to prevent accidents.
