Newest addition to the product line of American Hoist & Derrick Company's Marine Energy Division is the Sea Horse model 160 pedestal crane. Boom length ranges from 50 to 120 feet, with load ratings from 10,900 to 100,000 pounds. The Sea Horse is the latest in a long line of Amhoist cranes designed especially to meet the needs of offshore platforms, service vessels, and material-handling operations, both aboard ship and dockside.
All fabricated structural components are manufactured from mild steel. The mast is bolted to the deck and both fit around the stationary kingpost. The upper kingpost houses spherical roller bearings to resist thrust and radial loads. The deck also houses spherical roller bearings pressed into steel tires. These combine for smooth, safe load transfer from the crane to the mounting structure.
The boom is a mild steel, angle chord lattice structure that is bolted together. The standard boom point has four mainfall sheaves mounted on anti-friction roller bearings. A 3½-foot integral jib extension is standard.
Three winch units—main, auxiliary, and boom—provide ample rope capacity for each crane function. Each winch is a self-contained, completely sealed unit equipped with a spring-set, hydraulic-released automatic load-holding brake.
A dual swing system insures symmetrical load transfer and an efficient drive system. Each swinger is mounted at 90 degrees from the boom center line to provide a positive swing torque, minimizing front roller loads. All controls are spring-centered and provide deadman protection. The totally enclosed operating cab is located on the right side of the deck.
A single-gear pump with three separate sections powers all functions. A standard 6-cylinder diesel engine directly coupled to the hydraulic pumps provides a continuous 228 bhp at 2,100 rpm to all machine functions. The complete engine package is shock-mounted to reduce noise and vibration. The engine is centrally located on the machinery deck for maximum accessibility.
