Maintenance of lifting chain

1. The sprocket wheel shall be installed on the shaft without skew and swing. The end faces of two sprocket wheels in the same transmission component shall be in the same plane. When the center distance of the sprocket wheel is less than 0.5m, the allowable deviation is 1mm; when the center distance of the sprocket wheel is more than 0.5m, the allowable deviation is 2mm. However, it is not allowed to have friction on the side of the sprocket wheel. If the two wheels are too large, it is easy to cause chain disconnection and accelerated wear. Pay attention to check and adjust the offset when replacing the sprocket wheel.

2. The tightness of lifting chain shall be appropriate, too tight increases power consumption, and the bearing is easy to wear; too loose chain is easy to jump and fall off. The tightness of the chain is: lift or press from the middle of the chain, and the center distance between two sprocket wheels is about 2% - 3%.

3. The new lifting chain is too long or elongated after use, which is difficult to adjust. The chain link can be removed according to the situation, but it must be an even number. The chain link shall pass through the back of the chain, the locking piece shall be inserted outside, and the opening of the locking piece shall face the opposite direction of rotation.
