造成升降平台主轴断轴的原因很多，大多数属于使用不当，总结一下主要有以下几方面的原因。

1、升降机长期超负荷运行，特别是因使用维护不当造成外伤产生裂纹，而又长期超负荷使用。

2、主轴滑动配合表面润滑不良，升降平台在长期缺油的情况下运行，造成主轴磨损，出现较大的应力集中情况，进而出现疲劳裂纹，在冲击载荷作用下，最后出现主轴断裂。

3、装拆主轴上的零件时打伤或碰伤主轴，使主轴出现裂口，成为裂纹源，裂纹不断扩展，最后造成升降平台主轴断轴，装齿轮联轴器的轴肩处是主轴最弱的部位，应力最高，最易在此处出现断轴事故。
Parts assembly and disassembly spindle wounded or bruised spindle, spindle cracks appear and become a source of cracks, crack continues to expand, and finally result in Hangzhou lifting platform off the spindle shaft, shoulder mounted gear coupling is the weakest of the spindle site, the maximum stress, the most easily broken shaft accident occurs here.

4、为避免断轴事故的发生，杭州升降平台在使用过程中要严禁超负荷使用。维修人员必须定期检查固筒左支轮、游简左支轮、游筒右 支轮与主轴滑动配合表面的润滑情况。维修人员在拆装主轴上的相关零件如齿轮联轴器、固筒右支轮等处的切向健、游动卷筒的铜瓦时，严禁打伤或碰坏主轴。
To avoid breaking the shaft of the accident, in the course of the lifting platform to be prohibited overload. Maintenance personnel must be checked regularly left branch of the solid cylinder wheel, amusement Jane left outrigger wheels, swim tube slide right branch wheel and spindle mating surface lubrication. Maintenance personnel in the relevant parts such as spindle disassembly gear couplings, solid right branch wheel cylinder tangential health, etc., when the roll of copper tile swimming is prohibited wounded or damage the spindle.
