Gantry crane range indicator composition and working principle

1 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 of 0.5 meters,bridge gantry crane the allowable deviation of 1 mm; sprocket center distance of 0.5 meters above, the allowable deviation of 2 mm. But not with friction sprocket side phenomenon, if two series move too prone to derailments and accelerated wear. Replacing the sprocket must be careful to check and adjust the offset.

2-in. 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%.

3 The new  gantry crane  or by the use of chain elongation after long, difficult to adjust, remove links to look at the situation, but 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.

4 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.

5 The old gantry lifting chain can not be mixed with some new chain, or easy to have an impact in the drive, pull off the chain.

6-in. Lifting chain at work to remember to add 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.
