ASME B30.7-2001

Applies to the construction, installation, operation, inspection, and maintenance of base mounted drum hoists arranged for mounting on a foundation or other supporting structure for lifting or lowering loads, to derrick swingers, and to any variations which retain the same fundamental characteristics. The scope includes hoists which are powered by internal combustion engines, electric motors, compressed air, or hydraulics, and which utilized drums and rope. This volume does not apply to overhead hoists, car pullers, barge pullers, truck body hoists, or other hoists or winches used exclusively in horizontal pulling applications. Provisions of this volume do not encompass all of the safety precautions and safeguards applicable when hoist loads consist wholly, or in part, of personnel. When base mounted drum hoists are used as an integral part of other lifting equipment, this volume may not apply.
