Description

Technical Field

[0001] The utility model relates to a lifting equipment technology, in particular to a hand chain hoist for a container beam and plate welding assembly and a hook device thereof. Background Art

[0002] A hand chain hoist is a simple, portable, and manual lifting mechanism. It's also known as a magic hoist, chain hoist, chain hoist, chain hoist, chain hoist, or manual hoist. It primarily consists of a hand chain, hand chain pulley, ratchet, and gears. Pulling the hand chain rotates the hand chain pulley, which in turn drives the lifting chain to raise and lower the load. Hand chain hoists are suitable for lifting small equipment and cargo over short distances. They offer safety, reliability, easy maintenance, high mechanical efficiency, low chain tension, low weight, attractive appearance, and durability. They are widely used in factories, mines, construction sites, docks, shipyards, warehouses, and other locations.

[0003] When welding the inside of a container, it is necessary to pull the side wall of the container to weld the side wall of the container to the container bottom plate. When using a hand hoist to pull the side wall of the container, it is necessary to first fix one end of the hook and then release the lifting chain long enough. Then, connect the lifting chain to the side wall of the container, and then tighten the lifting chain with the hand chain until the bottom of the container side plate is in contact with the side of the container bottom plate. Only then can welding be carried out. However, when using the hand chain to drive the lifting chain to retract, before the lifting chain tightens the side wall of the container, all work is in vain, which reduces work efficiency and increases the workload of workers.
