Note the use of the rope hoist has a very important point needs special attention, that is, the load on the electric hoist, avoid non-load operation, but daily use still have a lot due to the use of the load operation has to a greater extent to avoid this problem, the introduction of electric hoist bridge.
It can guarantee a certain extent overhead electric hoist when the normal operation of the load, no load, Wire rope hoist bridge girders have L/1000 arch degrees, reaches the maximum allowable deflection under load should not be the main beam exceed L/700. In this range of camber and deflection, bridge wire rope electric hoist trolley is still able to maintain a normal working condition, so the bridge wire rope electric hoist double beam or single beam at the time of manufacture with L/1000 camber, you can to some extent, ensure that the load hoist can also be normal operation.
Again, the majority of new and old customers and friends, in order to ensure safety and efficiency, should not use the hoist load.
