In practical applications, the operating frequency of LD electric single beam crane is very high, so its driving wheel and reducer also need to operate frequently to meet the needs of equipment use.
If the gearbox of the crane is prone to wear and even leakage during repeated starting, stopping, and emergency stopping, is there any good solution for such problems?
When the gearbox in the crane has problems, the traditional way in the past was to repair it by welding or brushing, but neither of them has certain drawbacks. For example, welding repair can easily generate unavoidable thermal stress, causing deformation or fracture of components, while brush plating repair is more susceptible to thickness variation, and the problem still cannot be fundamentally solved.
So try to change the manufacturing materials of the gearbox components as much as possible and replace them with high molecular weight HDPE materials. This way, there will be no thermal stress caused by welding repairs, nor will it be affected by the thickness of repairs. Importantly, it can avoid the possibility of further wear and greatly extend the service life of the gearbox, and also reduce the occurrence of failures for cranes.
