Monorails and Underhung Cranes
|Publication Date:||16 April 2010|
Volume B30.11 includes provisions that apply 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 handoperated 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, but not limited to, nonvertical lifting service, lifting a guided load, conveyor systems, including power and free conveyors, and lifting or transporting personnel are not included in this Volume.
