About This Item


Full Description

B30.11 applies to the construction, installation, operation, inspection, testing and maintenance of underhung crane and monorail systems, track sections and load-carrying members, such as end trucks or carriers (commonly called trolleys) that travel either on the external or internal lower flange of a track section. The track sections include single monorail track, crane bridge girders and jib booms, all curves, switches, transfer devices and lift and drop sections. Provisions apply to both power driven and hand operated equipment in which the carriers are independently controlled. Items within this scope may be referred to as Equipment.

Provisions for similar equipment used for a special purpose, such as, non-vertical lifting service, lifting a guided load, conveyor systems, including power and free conveyors and lifting or transporting personnel are not included in this Volume.
