The correct use of lifting chain

  Lifting chain is an important part of all kinds of lifting machinery, it carries the weight of goods, is the arm of lifting machinery. If the lifting chain is used improperly, it is likely to cause it to break, causing extremely serious consequences. So how to use the lifting chain reasonably and increase its service life? The following by Qing Yuan Lijia rigging to tell you!

  1. The chain installed on the shaft should not tilt and sway. In the same transmission component, the end faces of the two sprockets should be located in the same plane, and the sprocket base distance is less than 0.5 meters, allowing an error of 1 mm; When the sprocket base distance is more than 0.5 meters, the error of 2 mm is allowed. However, it is not allowed to have a conflict on the side of the sprocket teeth, if the two wheels are shifted too much, the chain will be removed and the wear will be accelerated. It is necessary to carefully check and adjust the offset when replacing the sprocket.

  2. The tightness of the lifting chain should be appropriate, too tight to add power consumption, bearing easy to wear; Too loose a chain can jump and break. The tightness of the chain is: lifted or pressed from the middle of the chain, the base distance of the two sprockets is about 2%-3%.

  3. The new lifting chain is too long or stretched after use, difficult to adjust, depending on the situation to remove the chain, but it is necessary to be even. The chain link should pass through the opposite side of the chain, the lock plate is inserted on the outside, and the opening of the lock plate should face the opposite direction of the rolling.

  4. After severe sprocket wear, the new sprocket and new chain should be replaced together to ensure excellent meshing. You can't just replace a new chain or a new sprocket. Otherwise, the meshing is not good enough to accelerate the wear of the new chain or the new sprocket. Sprocket tooth surface wear to a certain degree should be used in time to turn over (refers to the adjustable surface of the sprocket). To extend the use of time.

  5. The old lifting chain can not be mixed with some new chains, otherwise it will simply have an impact in the transmission and break the chain.
