rope hoist fault common solutions

rope hoist used increasingly widely, often used to enhance, led moving, loading and unloading heavy objects, tank flip chip bonding, such as various sized concrete, steel and mechanical equipment installation and move, for construction and installation companies, factories, mines and civil construction and bridge construction, electric power, shipbuilding, automobile manufacturing, construction, roads, bridges, metallurgical, mining, slope tunnels, wells and other infrastructure construction management protection of mechanical equipment. I'll explain in the use of  rope hoist common failures occurred during what is usually a solution

       rope hoist motor voltage is normal, while the  rope hoist that is not working, it should be considered for other reasons, for example: motor is burned, overhaul the need to replace the motor.

     Wire rope hoist  long-term need, poor maintenance, the brake wheel and cover rust, brake wheel when starting off is not open, the motor only issued a "hum" sound, turn it up, causing  rope hoist does not work. At this time, you should remove the brake wheel, cleaning corroded surfaces, and then re-test; serious motor sweep chamber, but also make the motor does not rotate, found this situation, you should stop using the motor must be overhauled or replaced to ensure  rope hoist work. In addition, the production of non-overloading using  rope hoist, when the goods are excessively overloaded,  rope hoist crane does not move goods, the motor will only issue a "hum" sound, rather than running, and in severe burning motor, or even cause an accident, then should immediately stop reduce the cargo, the  rope hoist work at rated power.
