DEVELOPMENTS AND DESIGNS TO IMPROVE OFFSHORE CRANES

The Harnischfeger Corporation of Milwaukee, Wisconsin, has evolved an entirely new design of pedestal mounted crane, designed specifically for use on offshore drill rigs. The new crane has a maximum capacity of 50 tonnes and an 18.28 m long heavy duty boom complete with a 1.5 m whip extension specially designed for operation in heavy wind conditions. Boom extensions are available with pin connections for easy assembly or disassembly, giving lengths up to 36.5 m. For ease of handling and assembly, the crane has been designed in modular component form requiring only 16 pins and four bolts to complete assembly. There are six main components; the base, A-frame, power unit, gantry, cab and boom, and the heaviest component weighs only 16,000 lb. They are designed to be easily air lifted and assembled on rig or platform with minimum time and labor.
