Electric wire rope hoist repair common method

Electric wire rope hoist repair common method
Wire rope hoist speed is 8 m / min, increase the weight of 0.5 tons to 30 tons. Rope length can be customized according to customer requirements.  wire rope hoist  ody hanging in the car or walking along the beam, the operator on the ground with a button you can easily operate, in order to

Improve safety hoist also installed a limiter, these measures have effectively increased the electric hoist life. But may be used as long gourd or improper operation, some problems cause the device to malfunction, in this brief introduction of the common problems and electric wire rope hoist

Its repair methods:
1, the motor emits unusual noise, immediately stop and check whether the motor running single phase, or bearing damage, coupling axis errors and "sweep chamber" faults, these will make the motor abnormal sound, the sound of a different fault location and the level and tone a difference, single-phase operation, the entire

Issuing a regular motor suddenly strong suddenly weak "buzzing" sound. In short, the difference should be based on the noise, to find fault, for itemized repair and restore normal performance of the motor when the motor fault untreated, prohibit the use of gourds.
2, abnormal noise issued from the reducer, reducer fails, you should stop to check, first determine the reducer gearbox or bearing on whether to raise the oil prior to use, whether to use periodic oil change, if there is no lubrication required, reducer will not only generate excessive "buzz

"Sound, but also excessive wear or damage to the gears and bearings.
3,  Rope hoist  term application of the brake ring wear is too large, the brake spring pressure decreases, the braking force is reduced. The workaround is to adjust the brake bolt or replace the brake ring.
4, can not stop or to limit position is still parking, this happens, immediately cut off the power, the gourd forcibly stop. After stopping, repair contactors or stopper, serious damage can not be repaired and must be replaced.
5, winter construction, especially after the snow, the circuit no fault motor still does not start, the reason is the brake ring frozen to death, if this Shihai forcibly boot, it is easy to burn the motor. The solution is to open the motor cover, with a crowbar pry motor so that it can rotate freely can.
rope hoist components are: motor, transmission, drum and sprocket. Can be installed separately on the beam can also be installed in electric or manual single-beam, dual-beam, cantilever, gantry cranes and other use, is a small high-rise building, logging, warehouses ideal handling tools.
