A 100 ton chain block is actually not commonly used or common. As a large tonnage chain block, it is often used in ship maintenance situations. When large ships and cruise ships need to carry out high-precision component maintenance work during ocean voyages or maintenance periods, they can only use manual pulling of the chain to lift heavy objects. In addition, with the large tonnage of ship components, it is not surprising to use a 100 ton chain block to lift large tonnage objects.

In order to ensure a high safety factor when lifting heavy objects with a 100 ton hand pulled chain block, a single hook, double/multi head, and double/multi row chain design is adopted. Its upper and lower hooks have a load-bearing capacity of 1.2 times the standard weight. The coaxial chain arrangement not only provides convenience for operators, but also ensures that each chain is in excellent stress state.
