Most of the hooks with small load capacity (less than 3 tons) are directly fixed on the winch. In most cases, the weight of the hook itself cannot pull the steel cable closer and overcome the friction of the transmission mechanism and pull the rotor of the motor, so some special weight needs to be added.

Port rotating cranes, usually with a load capacity of 2.5 tons and 3 tons, are equipped with a hook head. Between the hook and the hook head, there is a round iron chain about 1/2 meter long, which allows the hook to have great mobility.

The purpose of using a spring hook head is to reduce the impact of the heavy impact on the hook. If a steel rope with sufficient elasticity is used, this kind of spring hook head is generally not needed, and it is only used in light forging cranes.
