Balance Crane, New Concept

Liftech developed a new crane concept, the Balance Crane, with smaller wheel loads and tie-down loads for the stowed condition. For stowage, the crane upper structure rotates about hinged connections at the upper waterside legs. As the boom and the trolley girder between the legs rotate up, the girder backreach, including the machinery house and stowed trolley, lowers but stays nearly horizontal. The boom hinge is relocated to near the landside rail. The dead load and operating wheel loads are comparable to those of conventional cranes. Operationally, the Balance Crane looks like and will work the same as a conventional STS crane.
