20T chain block use requirements and walking conditions

- Nov 27, 2018-

In the process of using 20T chain block, it is strictly forbidden to use the cable-stayed overload. To a certain extent, it is strictly forbidden to use other powers other than manpower. The 20-ton chain hoist must be confirmed before use. The transmission part and the lifting chain are well lubricated and the idling condition is normal.


The 20-ton chain block needs to check whether the upper and lower hooks are hung before lifting. The hoisting chain should be suspended vertically. There should be no twisted links when using, and the lower hook frame of the double-row chain should not be turned over. The operator should stand in the same plane as the bracelet wheel to sway the bracelet, so that the bracelet wheel rotates in a clockwise direction, so that the weight can be raised; when the bracelet is reversed, the weight can be slowly lowered.


When the 20-ton chain block is lifting heavy objects, it is strictly forbidden for the personnel to do any work and walking under the heavy objects, so as to avoid major accidents. During the lifting process, no matter whether the weight rises or falls, the bracelet is swayed. The force should be even and gentle, do not use too much force to avoid the bracelet jumping or snap ring.
