Crane chain exactly how to maintenance and maintenance
Stainless steel lifting chain can according to different weight lifting height adjusting the length of the chain, is fetching device important essential to improve, crane, crane productivity, plays an important role in expanding the scope of crane. Then the crane chain exactly how to maintain?
1 wheel on the shaft should be no skew and swing. In the same transmission components of the end surfaces of the two sprocket should be located in the same plane, the sprocket center distance in 0.5 meters, the allowable deviation 1 mm wheel center distance of 0.5 meters, the allowable deviation 2 mm. But no friction chain gear side phenomenon, if two shift is too large to take off the chain and accelerated wear. In the replacement of the sprocket must check and adjust offset.
2 lifting chain tightness should be appropriate, too tight to increase power consumption, easy bearing wear loose chain to jump and take off the chain. The degree of tightness is lifted from the chain chain: the middle or under pressure, the two sprocket center distance is about 2%-3%.
3 new lifting chain is too long or use after elongation, difficult to adjust, can see to remove the link, but must be an even number. Links should be back through the chain, the lock sheet is inserted in the outside, the locking piece in the opposite direction of the opening in the rotating.
The 4 sprocket wear serious, should be replaced at the same time the new sprocket and chain, to ensure good meshing. Not only change the new chain or chain wheel. Otherwise it will cause improperly meshed accelerated wear and tear of new chain or chain wheel. Sprocket tooth wear to a certain degree should be promptly after turning over the surface (the surface adjustable sprocket used). To extend the use of time.
5 old onwards and part of the new chain of mixed heavy chain, otherwise easily in the transmission of shock, breaking the chain.
6 lifting chain at work to remember the timely filling of the oil. The lubricating oil must enter the clearance of roller and inner sleeve, so as to improve the working conditions, to reduce wear and tear.
