When some abnormal conditions occur during the use of the hand chain hoist, it means that the hand chain hoist has quality problems, and it is not recommended to continue to use, and it needs to be used after maintenance. Next, Guanhang will take you to check the abnormal condition of the chain hoist.

Abnormal noise: the chain wheel is stuck with foreign matters, the chain is deformed and worn, the cover is deformed, the internal parts are loose, and other reasons may cause the chain block to make abnormal noise during use.

Inaccurate travel: because the inside of the hand block is gear transmission power, and the user is driven by pulling the handle, the hook under the handle will also rise and fall the corresponding travel when the user pulls the handle for one circle. Therefore, when the stroke is unstable, it means that the internal gear has failed.

Difficult to pull the handle: the power system inside the hand block can amplify the power, so the user usually does not need too much force when pulling the handle. If it is difficult to pull the handle, it indicates that there is overload or hoist failure.
