Bridge cranes are a typical lifting equipment. When repairing welding, it can be used in several ways, but how to weld it better? Let's let Weihua Crane Co., Ltd. come to answer your questions.
The active wheel and the large speed reducer of the crane are frequently operated. Repeated reverse rotation and emergency stop will bring the torque and vibration to the shaft of the reducer, so it will easily cause leakage.
When leakage occurs, the traditional methods are mainly repaired by repair welding or brush plating. However, the thermal stress generated by the repair welding high temperature cannot be completely eliminated, and it is prone to bending or breaking; the brush plating is limited by the thickness of the coating and is easy to peel off, and both methods are to repair the metal with metal, under the combined action of various forces, It will also cause repeated wear and tear.
In order to make up for the defects of traditional repair, it is now based on polymer composite materials, with superior adhesion and compressive strength. It can absorb the shock and vibration of equipment, prevent the possibility of re-wearing and extend the life of the equipment components.
In summary, the technical level of research and development of the equipment has not stopped. If you have the intention to purchase lifting equipment, you can contact Weihua Crane Co., Ltd.
