For 16/3.2～50/10t cranes, there are two separate main and auxiliary lifting mechanism with two hook.

Main hook is used for lifting heavy objects and auxiliary hook can be used for lighter ones. And the auxiliary hook can also be used to help the main hook tip and turn over workpiece. Should pay more attention that never allow two hook lifting two objects at the same time. The weight of the object is forbid to surpass the rated lifting capacity of main hook when they work together.
