In daily work, it is necessary to check the appearance quality of the galvanized hand chain frequently. The main contents are as follows: 1. Check whether the inner/outer chain is deformed, cracked and corroded; 2. Whether the pin is deformed or rotated, and rust; Whether the roller is cracked, damaged or transitional wear; 4. Whether the joint is loose or deformed; 5. Whether there is abnormal sound or abnormal vibration during operation, and the lubrication condition of the chain is good.
In addition to checking the appearance quality of the galvanized hand chain, the overall performance of the galvanized manual lifting chain also needs to be maintained and maintained. For example, check that the sprocket is mounted on the shaft without skewing and swaying. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is below 0.5 m, the deviation is allowed to be 1 mm.
Note that the galvanized hand chain should maintain a moderate tightness. If the sprocket is found to have significant wear, the new sprocket and the new chain should be replaced at the same time to ensure good engagement. It is not possible to replace a new chain or a new sprocket alone. Failure to do so may result in poor engagement to accelerate the wear of the new or new sprocket. After the sprocket tooth surface wears to a certain extent, it should be turned over in time (refer to the sprocket used for the adjustable surface) to extend the use time.
