Annotation and contents

ASME has been defining crane safety since 1916.

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

B30.11 is to be used in conjunction with equipment described in other volumes of the ASME B30 series of safety standards.

Careful application of these B30 standards will help users to comply with pertinent regulations within their jurisdictions, while achieving the operational and safety benefits to be gained from the many industry best-practices detailed in these volumes.

Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of monorails and underhung cranes with B30 equipment, plus all potential governing entities.
