Electric hoist is mainly used for lifting, pulling, loading and unloading heavy objects, generally divided into wire rope electric hoist, chain electric hoist and explosion-proof electric hoist, it is a kind of light and small lifting equipment, widely used in all walks of life, generally installed in single beam crane, bridge crane, gantry crane, hanging crane, The following is to introduce the structure and working principle of the electric hoist.
Electric chain hoist
Remote control electric hoists consists of mechanical and electrical parts, mechanical parts including: reducer, lifting motor, walking motor, walking wheel, goods breaker, drum device, hook device, coupling, etc.; The electrical part includes: power switch (iron box switch), power supply cable, safety sliding contact line, collector, lifting belt sling
, control box, etc. Electric hoist adopts mechatronic integration design, power supply through sliding contact line, use handle operation, control loop through the control box to control electric hoist lifting motor, walking motor, to achieve the purpose of lifting equipment.
The working principle of electric hoist is very simple, start the lifting motor first, lift the weight to the appropriate height, and then start the operation of the motor to transport the weight to the designated position, running the car in the lower edge of the simplex steel beam walking. When walking, an electric motor is used to drive the wheels on both sides of the car.
Electric hoist is the necessary machinery to improve labor efficiency and improve working conditions. Electric hoist with small volume, light weight, simple operation, easy to use and other characteristics, used in industrial and mining enterprises, storage, wharf and other places. Most electric hoists are operated by people using buttons on the ground, or they can be operated in the driver’s room or remotely controlled by wire (wireless).
