How to avoid explosion-proof electric hoist mechanical friction

     Explosion-proof hoist due to its characteristics and more for a special place, but how to avoid friction between two mechanical components to extend the life of  Wire rope hoist  to avoid mechanical friction or impact sparks and dangerous temperature danger it? The following for you to do the following description:
       1 explosion-proof  Rope hoist  rope surface should be no broken wires.
       2, the rope should be reliable lubrication of measures to reduce the wire rope and reel, guide rope and pulley friction between.
       3, the brake should be installed inside the flameproof enclosure.
       4, explosion-proof hoist orbit joints should be smooth, flat, the car should be no impact on the operation of the phenomenon.
       5, good maintenance inspection work to ensure proof electric hoist trolley starting and braking stability and prevent skidding.
       6, there are two tracks in a unified proof hoist operation above, electric hoist should be fortified shock absorbing devices. Buffer device shall be non-metallic materials, the surface resistance of not more than 10
       7, when a metal barrier proof  rope hoist  working environment is large, to avoid an obstacle collision with a metal hook, the hook should be marked on the outer surface of the pulley plates such as the prohibition collision warning label.
       8, explosion-proof electric hoist exposed sectors with a relatively friction movement speed measures should be taken, such as the involvement of the wire rope and drum hoist trolley line speed and running speed on the track shall be greater than 25m/min.
