Crane Hoist Specs: overhead bridge
SGUH 1t A to SGUH 5t C
Crane and hoist load ratings, duty classifications, and design parameters for overhead bridge cranes (single/double girder, top running/underhung), gantry cranes, jib cranes, monorails, and electric chain/wire rope hoists. Covers CMAA Classes A-F, FEM/ISO mechanism groups M2-M7, safe working load, span, bridge/trolley/hoist speeds, design life, and load spectrum factor per ASME B30 series, CMAA 70/74, FEM 1.001, ISO 4301-1.
