Cargo handling equipment2

All fixed capacity motors, whether high or low speed, require a high flow at low pressure to obtain high light hook speeds and consequent short cycle times.

The hoisting of the cargo is effected by a hoisting winch driven by a hydraulic motor that provides a constant torque in both directions of rotation and at all speeds within the regulation range of the motor.

The crane jib is raised and lowered by means of a luffing winch which is constructed in a similar manner to the hoisting winch.
