Accidents caused by the use of chain hoists

Although the chain hoist may seem like a small lifting tool with simple structure and operation that everyone can use, accidents can also occur if one does not understand its mechanical performance, operates improperly, manages and maintains poorly.

In December 1994, Cao, a cement worker at a factory site of a certain company, was dismantling the inner formwork of a concrete river. Due to several steel formwork stuck together, he couldn't remove them, so he brought a chain hoist. During use, he hooked the hook of the chain hoist directly onto the card hole of the steel template. Due to the small size of the hole and the thick hook, only a small amount of the tip of the hook can be hung into the hole. After struggling with the chain hoist, the hook bounced back from the hole and knocked two of Cao's front teeth off.

On April 2, 1999, Xu, a contracted farmer at a company's structural construction site, used a 2-ton chain hoist to transport a section of monorail lifting beam. After the rail was lifted, they started the next step of construction without locking the chain hoist or adding any padding underneath the rail. At this point, the self stabilizing function of the chain hoist suddenly failed, causing the suspended object to suddenly fall and injuring Xu's right foot.

In June 2005, Zhang and others from three woodworking teams of a certain company were carrying out the lifting of a 2l meter beam in the main factory building. Due to the inability of the crane to lift the beam in place, they tied a chain hoist to each end of the beam and "snatched" it inward, forcing it to be in place. At that time, Zhang was riding on a beam to command. When there were still 4130 millimeters left to reach the target, one of the chain hoists lost control on its own, and the suspension chain completely detached, causing the concrete beam to suddenly sway outward and throw Zhang off the beam. Fortunately, he had fastened his seat belt beforehand, which saved him from a fatal accident.

On October 27, 2007, during the installation of a boiler dust collector using a chain hoist at a heating construction site of a certain company, Gai and others experienced a detachment of the chain hoist, causing the object to fall and shatter Gai's right thumb into a fracture.
