Description

This Standard provides minimum structural andmechanical design and electrical component selectioncriteria for ASME B30.20, Below-the-Hook LiftingDevices.

The provisions in this Standard apply to the designor modification of below-the-hook lifting devices. Compliancewith requirements and criteria that may beunique to specialized industries and environments isoutside the scope of this Standard.

Lifting devices designed to this Standard shall complywith ASME B30.20, Below-the-Hook Lifting Devices.ASME B30.20 includes provisions that apply to themarking, construction, installation, inspection, testing,maintenance, and operation of below-the-hook liftingdevices.

The provisions defined in this Standard address themost common and broadly applicable aspects of thedesign of below-the-hook lifting devices. A qualifiedperson shall determine the appropriate methods to beused to address design issues that are not explicitlycovered in the Standard so as to provide design factorsand/or performance consistent with the intent of thisStandard.
