Lifting Chain Operation Efficiency

The lifting chain can be adjusted according to the lifting height of the lifting height. The length of the chain is essential for the crane. The important lifting device plays an important role in increasing the working efficiency of the crane and enlarging the working range of the crane. Lifting Chain Maintenance and repair is essential, the following six small points to talk about its specific maintenance and repair.

1. The sprocket should not be skewed and swung on the shaft. In the same drive assembly, the end of the two sprockets should be in the same plane, the sprocket center distance of 0.5 meters below the allowable deviation of 1 mm; sprocket center distance of 0.5 meters or more, allowing a deviation of 2 mm. But not allowed to have a friction sprocket teeth side of the phenomenon, Lifting Chain if the two rounds are too easy to produce off the chain and accelerated wear. Care must be taken to check and adjust the offset when replacing the sprocket.

2. Lifting chain of the tightness should be appropriate, too tight to increase power consumption, easy wear and tear; too loose chain easy to beat and off the chain. The degree of elasticity of the chain is: Lifting Chain from the middle of the chain to lift or press the two sprocket center distance of about 2% -3%.

3. Old lifting chain can not be mixed with some of the new chain, or easy to produce shock in the drive, pull off the chain.

4. Sprockets wear serious, should also replace the new sprocket and the new chain to ensure good engagement. You can not replace the new chain or new sprocket separately. Otherwise it will cause poor engagement to accelerate the wear of new chains or new sprockets. Lifting Chain Sprocket tooth surface wear to a certain extent should be used in time to turn (referring to the use of the sprocket). To extend the use of time.

5. The new lifting chain is too long or elongated after use, it is difficult to adjust, see the situation to remove the chain, but must be even. The chain should pass through the back of the chain, Lifting Chain the locking tab is inserted outside, and the opening of the locking tab should be in the opposite direction of rotation.

6. Lifting chain in the work to remember the timely filling of lubricants. While the lubricating oil must enter the clearance between the roller and the inner sleeve in order to improve the working conditions to reduce wear.
