Crane Operating

Crane Operating

Federal Wage System Position

Work Performed

This standard covers nonsupervisory work involved in the operation of cranes to lift, transport, and position materials; to dig and move earth or other materials; to drive pilings; or to destroy obsolete structures. Cranes use attachments such as hooks, clamshell buckets, orangepeel buckets, dragline buckets, magnets, pile-drivers, demolition hammers, and other special material handling devices.

Skill and Knowledge Requirements

required of grade 9 boom crane operators, grade 11 operators must be skilled in operating cranes at all boom lengths, angles, and positions. They must be skilled in making rapid lifting capacity judgments during continual position changes. They must be skilled in operating near or at the crane's lifting capacity and within extremely congested areas. They must be skilled in producing exact movements while precision setting loads onto or into other objects, e.g., positioning and holding a hull section of a ship while it is welded into place. Grade 11 operators must be skilled in simultaneously operating the crane's controls, making difficult clearance judgments while watching the moving load and boom, and compensating for variations in the crane's lifting capacity during position changes. This demands intense concentration, unusual alertness, and an exceptional degree of visual and physical coordination. U.S. Office of Personnel Management 6 Crane Operating, 5725 TS-17 June 1971
