Lifting chain maintenance work should pay attention to what?


Hoist equipment is an important branch of the industry chain, the two industry occupies a very important position, rather like mine with a chain and anchor there, and of course the name suggests lifting chain that is primarily used for lifting equipment in lifting a load-bearing rod effect. Lifting chain lengthUse of time will occur in certain deformation and damage, then in their daily work should pay attention to what we have maintained all?

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, 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 moved over Big prone to de-chain and accelerated wear. Replacing the sprocket must be careful to check and adjust the offset.

2load 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 Do not mix:

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.

4 Replace with new sprockets and new  load chain:

    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  Used to extend the use of time.

5. Appropriate demolition:

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 maintenance work to remember when you want to remember to add oil, and lubricants must enter roller and inner sleeve with the gap in order to improve working conditions and to reduce wear.
