The explosion-proof chain hoist manufacturer introduces you: When using the explosion-proof chain hoist, when pulling the hand zipper strip of the explosion-proof chain hoist, the reason why it does not move or the tensile force increases:
First, the lifting method using explosion-proof chain hoist is incorrect. The correct method of lifting is to properly suspend the lifting weight inside the lifting hook before lifting, and pull the hand zipper bar vertically and uniformly on the same plane so that the weight can be uniformly and safely lifted to the specified position. However, some users will have a diagonal lift during the lifting process, or the speed will be faster and slower during the operation. This is the main reason for the difficulty in lifting, and I hope that the operators of explosion-proof chain hoists will pay attention to it;
2. The heavy load is severely overloaded. If overload occurs during the lifting process, it will not only cause laborious lifting during lifting, but also cause serious damage and deformation to various parts of the explosion-proof chain hoist.
Third, the card chain situation occurred during the operation. If the explosion-proof chain hoist does not straighten the lifting chain and hand zipper before the lifting operation, the phenomenon of chain jamming will be found during the lifting operation;
Fourth, if the chain is deformed, rusted, corroded or worn, causing the chain to fail to engage the sprocket well, it will directly lead to difficult lifting conditions. Therefore, when it is difficult to lift, it is recommended that the operator check the condition of the explosion-proof chain hoist chain.
The above is what the explosion-proof chain hoist manufacturer introduced to you. The reasons for the difficulty in lifting the explosion-proof chain hoist during the lifting operation, and some solutions when it is difficult to lift, for your reference.
