Areas of application

LENNIX® Pro is a control and regulation system which enables ship-to-shore gantry cranes to position their loads quickly and to reduce the risk of collision. It independently eliminates the unavoidable oscillations that occur while the crane is in operation. It eases the crane operator’s job and supports inexperienced operators while facilitating the automatic positioning of the crane. The danger of collision is thus reduced because the spreader hangs steadily at the end of every crane transaction each time.

The control and regulation system in question is comparable with the procedure of an experienced crane operator having to take adequately timed countermeasures. The desired speeds that are set by the crane operator in the manual operation mode are controlled by acceleration and braking processes so that swaying movements that occur during operation and after stopping are automatically eliminated. This in turn enables a quick positioning of the load.

The controller includes torsional vibration damping. Trim, list and skew cylinders are used to calm down the torsional vibrations of spreader during handling operation.
