Kongsberg Dual Drag Link crane (Subsea)

Dual Draglink Crane has increased cover area of full load, outstanding max load lifting height enabling long and wide arrangements We will no longer sell this product and it is being phased out. Providing unique lifting performance, the Dual Draglink Crane has increased coverage area on full load, outstanding max load lifting height enabling long and wide arrangements. The crane is designed to handle both steel wire and fibre rope. We offer a range of offshore cranes up to 400 tonnes load using field proven fibre rope handling technology. The cranes are fully integrated with our deck machinery handling and control systems and offer unparalleled performance as well as reliability and comfort. Through our cable traction control technology using fibre rope, our cranes can operate at virtually unlimited depths. Because the selected rope has neutral buoyancy, the crane can handle loads to its full rated capacity down to its maximum water depth. Cranes using heavy steel wire must begin derating at depths more than about 700m, so by 2,500m a 400t wire crane can only handle the same load as a 250t FRC. The dual draglink crane can handle both fibre rope and steel wire and has a geometry providing unique lifting performance. The drag link geometry provides a good working height and allows for short radius operations to make use of the deck area near the pedestal. The horizontal boom provides active heave compensation (AHC), significantly increasing the life time of the lifting line compared to when AHC is performed by means of the winch. Our rope management system monitors rope condition enabling abraded or damaged sections to be easily repaired by splicing onboard.
