Master the key points of safe use of explosion-proof electric hoist
Explosion-proof electric hoist is mainly used in places where there is explosive gas mixture composed of combustible gas or steam and air.Due to the use of the environment and the special field, so in the use of the need to pay attention to different with the ordinary electric hoist, the following small series for you to introduce, safe use of explosion-proof electric hoist need to understand and pay attention to what points.
1. explosion-proof electric hoist mechanical parts take flameproof measures, in order to prevent electric hoist running friction, collision sparks, the relevant parts in the use of electric hoist do the following treatment:
(1) appropriate amount of mechanical oil shall be injected in lifting and running the reducer.
(2) the hoist drum, wire rope should be coated with grease.
2. the choice of explosion-proof electric hoist best requirements, limit on the left and right stop block and limit device connection apply made of bronze or stainless steel.
3. electric hoist normal working time each surface temperature does not exceed 110℃.
4. the electric components of electric hoist include: lifting and running motor, control box, control button, limiter, etc., all adopt self-integrated flameproof equipment.
5. Soft cable type power supply lead-in.
