Description

LIEBHERR BOS 2600-25 D Lit offshore crane. Excellent overall condition. Only 590 hours on the engine. The crane is located on key-side in Norway – readily prepared for quick pickup/installation by single lift.
The crane is prepared for a single lift installation.
Upon request the actual lifting capacity of 25 to can easily be increased by upgrade to 2 or 3-Falls hook reeving. A (conical) pedestal adapter is available. A pedestal with a length of 9 m is available.
