Stage-specific hoist use, maintenance and testing

   Stage-specific part of the  manual hoist  electric hoist in strict accordance with touring exhibitions requirements design, black surface treatment, 110 volt control circuit heat treatment, forming a steel chain guide plate to the positive and negative way and designed to be used around the clock, with adjustable screw limit switches, higher reliability, chain galvanized, rust, grease installed in the gear box, to prevent the oil droplets penetrate into the arena.
Stage electric hoist used:
Electric hoist operating voltage and frequency are marked on the motor nameplate rated voltage on in connection stage before powering electric chain hoist definitely want to check these figures consistent with those of the supply voltage. Stage hoist hanging point should be an appropriate size to accommodate the arena of electric chain  lift hoist  hook or hooks at the top of the eye and allow it, on a modest placed in the saddle and it must be competent enough to support the crane lifting capacity at maximum power .
Stage electric hoist maintenance:
1, electric hoist initial lubrication:
Bearing Chain: refining of the entire length will need to be lubricated, including through the chain CHAIN ​​place to be determined is the contact point between the connecting rod is to be properly lubricated.
Gearbox: ambient temperature is about -10 ℃ to +50 ℃ between, you should use 220mm2 / S 40 ℃ temperature and high pressure gear oils with additives, gear oil specifications for DIN51502CLP220.
2, electric hoist objects surrounding the removal of:
Electric chain hoist will need to be hung in a place without hindrance. Suspension point should be a position that allows carrying hooks and any anticipated load for rising and falling action unhindered. Lumps must not hit bottom ground, if there is a need,hoist and trolley in the refining end of the slack adjustment CHAIN ​​stopped position.
Stage electric hoist final test:
Electric chain hoist on stage after completing the assembly, but the crane being used in normal operation, the following procedure should be performed. Isolated Power: Check all mechanical and electrical connections and connections are locked and is solid.
