Overhead and Gantry Cranes - General Requirements |
||||||
|
Overhead and/or gantry cranes may not be modified and re-rated unless the
modifications and the supporting structure are checked thoroughly for the new rated load
by a qualified engineer or the equipment manufacturer. The rated loads of the crane shall be plainly marked on each side of the crane. If the crane has more than one hoisting unit, each hoist shall have its rated load marked on it or on its load block. The potential for overloading the crane increases if the hook-up person and/or the operator does not know the rated capacity. Only employees selected by the employer or the employer's representative as being qualified to operate a crane shall be permitted to operate the crane. A preventive maintenance program based on the crane manufacturer's recommendations shall be established. |
