It allows the damping of head-block, spreader and container oscillation generated by acceleration / deceleration of trolley and gantry
| MAIN FEATURES | |
| lt is achieved by nr. 4 winches with crossed ropes that give the pull force required in order to damp the spreader oscillations. The force is high when ropes are pulled, while it is small when ropes are released. In this way it occurs a force with an horizontal component which opposes the oscillation force. There is a prompt damping. | |
