(1) check the wear and damage of internal gear ring and external gear sleeve teeth. The tooth wear of lifting mechanism and moving mechanism shall not exceed the above scrapping standard

relative to Jixi, a resource-based city (2), check whether the coupling has fatigue cracks. You can use a microscope with a magnification of not less than 20 times to observe whether there are fatigue cracks. You can also judge whether there are fatigue cracks by knocking sound or observe whether there are fatigue cracks by oil immersion method. If cracks or even peeling lines between the anti-wear layer and the base metal are found, replace them with new parts
