Explosion proof electric hoist requirements

Explosion proof electric hoist is usually explosion-proof wire rope electric hoist, in high temperature, moisture or dangerous gases environment, must use explosion-proof electric hoist.

Explosion proof electric hoist has much higher requirement on sealed than the ordinary CD1 / MD1 wire rope hoist, while in performance and operation also have higher requirements.

A. Explosion proof electric hoist electrical components include: lifting and running motor, control box, control buttons, limiter, etc., using self-contained flameproof equipment and cable-type power supply introducer.

B. When explosion proof electric hoist in normal working, the surface temperature can not exceed 110 ℃.

C. Mechanical parts should take measures to prevent explosion, in order to prevent the electric hoist appearing high temperature sparks because of friction, impact during operation, the relevant parts should be handled: lifting and running reducer should infuse the appropriate mechanical oil; The drum, wire rope should be smeared with grease; limit lever stop block and limiter joint should use bronze or stainless steel.
