A chain hoist is assembled from multiple components, among which the hook is one of the important components. Hand pulled hoists are divided into upper and lower hooks. When using a hand pulled hoist to lift heavy objects, the upper hook is hung on a fixed point, and the lower hook is used to hang the heavy object. Pulling the hand chain bar achieves the lifting operation of the heavy object.

Before using the chain hoist, a comprehensive and careful inspection of the hook should be carried out. If abnormal binding and hanging are found to be the main cause of hook wear in addition to normal use, we should correctly bind heavy objects; In addition, when encountering hooks with unclear tonnage and hook wear that has not yet reached the scrap standard, operators must conduct a re inspection. After passing the inspection, they can be used normally.

The hook of the chain hoist comes into direct contact with the lifted object and is prone to wear and tear during long-term use. Therefore, it is necessary to conduct a careful inspection before each work. If there are any abnormal situations, the use should be stopped immediately and a new hook should be replaced to prevent the hook from breaking during the work process.
