Crane chains need to pay attention to what issues routine maintenance

   Cranes are part of a large machine, once the losses will be more serious problems, so the routine maintenance of the crane is very necessary. Wherein maintenance is one of a chain. Then the routine maintenance crane chains to pay attention to what the problem?
   Lifting chain tightness should be suitable, tight increase power consumption, bearing wear; chain is too loose and easily beating off chains. The tightness of the chain: from the middle of the chain lift or pressure, the two sprocket center distance of about 2% -3%.
   Sprocket mounted on the shaft should not skewed and swing. In the same drive sprocket assembly in two end should be in the same plane, the sprocket center distance in the 0.5 m or less, the allowable deviation of 1 mm; sprocket center distance at 0.5 meters above, the allowable deviation of 2 mm. But does not allow friction chains.

Drop Forged Chain Series

   Sprocket wear serious, it should also be replaced with new sprocket and a new chain, to ensure good engagement. Not just a single or a new replacement chain sprocket. Otherwise it will cause poor acceleration engaging new chain or a new sprocket wear. Sprocket tooth wear to a certain extent should be promptly turned over to use (refer to the surface using the adjustable sprocket). To extend the use of time.
   The new lifting chain is too long or elongation after use, difficult to adjust, you can remove the link to see the situation, but it must be an even number. Back through the chain link should the locking plate inserted on the outside, the opening of the lock piece to be rotated in the opposite direction towards the.
   Lifting chain timely to remember at work filling oil. The lubricants must enter roller and inner sleeve with the gap in order to improve working conditions in order to reduce wear and tear.
  The old part of lifting chain with a new chain can not be mixed with, or easily generate impact in the drive, pull off the chain.
