Bridge crane trolley and wheel wear reducer leaking how to fix?

In front of us a  bridge crane  power failure causes and treatment measures, today we introduce two additional overhead crane failure, leakage and carts trolley gear reducer and active wheel wear, for these two failures, we How should it be excluded? Specific analysis is as follows.
Fault one, car reducer leakage
Bridge crane trolley gear due to vibration, abrasion, pressure, temperature and other factors, the combination of surface sealing parts often appear static leakage. Traditional treatment methods to remove reducer, replacing gaskets or sealant applied, but time-consuming and difficult to ensure the sealing effect, will appear again in the operation of leakage, so now use more polymer composites scene governance leakage. Polymer-free disassembly repair and materials have excellent adhesion, oil resistance and 350% elongation, good to overcome the impact of vibration reducer, repair effect is more effective than traditional methods.
Failure II, carts and active gear wheel wear
overhead bridge crane initiative running gear wheels and carts frequently repeated emergency stop and parking will cause reverse gear torque of each axis, vibration increases, could easily lead to leakage. Such problems occur, the traditional method and more to be machined after welding or repair the main brush, but there are some drawbacks both: high thermal stress generated by welding can not be completely eliminated, prone to bend or break; the brush plated by the coating thickness limit is easily peeled off, and the above two methods are metal with metal repair, you can not change the "hard to hard" with the relationship, the combined effect of the force, will cause wear again. Now the latest repair methods mostly based polymer composites with superior adhesion, excellent compressive strength and other performance.overhead gantry crane Applied Polymer repaired, neither welding thermal stress on the repair thickness is not restricted, while products with metallic materials do not have the concession, can absorb shock and vibration equipment, to avoid the possibility of re-wear and greatly extended equipment component life, save a lot of down time, creating significant economic value.
