Lifting chain wear occurs mainly between the tip of the shaft and the sleeve. Intestinal Shui makes room air becomes large, the chain becomes longer, until the chain is not exactly correct given distance and timing sprocket ho together, or not in dimension. Sometimes lifting chain lin damage or wear chain guide plate and between the roller and the sleeve between the rigging, lifting chain will lead to failure. Lifting chain becomes longer due to wear is a gradual process, the following look at the three stages of lifting chain wear lifting chain, as follows: The first stage is the initial running, time is short. Tip axis and bumps on the sleeve is worn away the best lifting chain, small heart was Bo monthly level. The second stage is scheduled rough and slow wear Run confusion. At this stage, shoot axis proper pots in a sleeve, to get the correct bearing area sufficient lubrication. The third stage is relatively fast wear stage. This stage lubrication may be or become invalid, or throw a hard layer of sodium shaft and the sleeve surface is worn away, or longer chain. So that the load of individual nodes increased dramatically. When the load exceeds the yield limit. Chain fat cow plastic deformation chain plate, chain plate hole is stretched, causing the chain does not work properly. Selection lifting chain are the following items: 1. Inside / outside links deformation, cracks, corrosion 2. embroidered pin is deformed or turn lifting chain packaging, embroidery eclipse 3. Roller whether cracks, damaged by excessive wear. The lifting chain is loose joints deformed 5. operation vibration abnormal sounds or abnormal, chain lubrication is in good condition. Lifting chain price is based on the different types, specifications, models, materials lifting chain lifting chain administered prices. Chen power lifting chain models: diameter 6 ~ 20mm lifting chain, including 80 and 100 lifting chain lifting chain types. Lifting chain chain can be adjusted according to the height of lift lifting objects of different lengths crane essential extract important means to improve the operational efficiency of the crane to expand the operating range of the crane plays an important role.
