Advantages at a glance

Specially designed as a crane around the leg, it facilitates space-saving positioning on the ship despite the size of the crane. The parallel jib makes it possible to park the jib over one of the ship's front legs. Positioning the crane in this way prevents blocking of the free area on deck, which can be used to load the ship.

The combination of swivel bearings, slewing mechanisms, winches and the Liebherr Litronic system ensures precise positioning as well as exact movement of the loads with reduced fuel consumption. Together with the powerful electro-hydraulic drive, this guarantees optimum control of the equipment in all operating situations.

The CAL can be deployed as a heavy duty crane for the installation and maintenance of offshore wind turbines. At a maximum of 1,700 tonnes, the enormous lifting capacity of the crane facilitates the installation of turbines and rotors with more than five megawatts as well as loading and subsequent installation of heaviest foundations.
Another area of use for the CAL is in setting-up equipment for oil and gas extraction. In this case, the crane can be used to build and dismantle platforms or other constructions.
