Group crane electric hoist requires group crane accessories
Electric hoist is a kind of small equipment used in lifting engineering. Because of its convenient use, it has been widely used in daily work. The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. Its disadvantages are: large length dimension, large width dimension, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low-voltage control, which increases the safety of the control system. However, many people do not have much knowledge about the use of electric hoists, and some problems will occur during use, which will affect the smooth operation of electric hoists.

The electrical control department adopts low-voltage control, which increases the safety of the control system. Next, let me briefly introduce the requirements of electric hoists for group hoisting parts hooks.
1. During use, the changing angle of the electric hoist accessory hook should be kept within 10 degrees, that is, the changing angle of the hook body should not exceed 10 degrees.
2. The protection of the hook should be done well. The hook should be kept clean and free of cracks, sharp corners, burrs, peeling and other defects.
three. The hooks of defective electric hoist lifting accessories shall not be repaired by welding and shall be used continuously.
4. There must be no cracks, white spots and inclusions in the hook that affect the safety of the hook.
5. The dangerous part or the hook of the hook should not be plastically deformed; the thread of the hook should not be corroded.
