SUBJECT:         Interpretation of 1910.179, Overhead and Gantry Cranes

The position of OSHA regarding the application of 29 CFR 1910.179 to monorails, monorail cranes, top running single girder cranes and overhead hoists has not changed since our 1972 interpretation by John J. Klocko. Such equipment is not covered under 1910.179. Prior correspondence reiterating this position are attached for your reference.

Hazardous operational aspects observed by OSHA field staff pertaining to monorails, monorail cranes, top running single girder cranes and overhead hoists, should be regulated under Section 5(a)(1) of the Act. Such enforcement sections should reference applicable portions of the pertinent ANSI standard and conform with guidelines in the FOM. ANSI standards for lifting devices and for which there are no applicable OSHA standard include:

ANSI B30.11 Monorail Systems and Underhung Cranes

ANSI B30.16 Overhead Hoists

ANSI B30.17 Overhead and Gantry Cranes (Top Running Bridge, Single Girder, Underhung Hoist)
