Hoisting Operator Tower Crane Endorsement (2011-07-19)

B30.10 includes provisions that apply to hooks used for lifting and load handling purposes, in conjunction with equipment described in other volumes of the B30 Standard. Hooks supporting a load in the base (bowl/saddle or pin hole) of the hook, are covered in Chapter 10-1. Hooks that may be loaded in other than the base (bowl/saddle or pin hole)are covered in Chapter 10-2. This safety standard offers comprehensive solutions applying to the fabrication, attachment, use, inspection, and maintenance of this equipment.

Since 1957 successive editions of the Handbook of Rigging for Construction and Industrial Operations have delivered proven solutions for erecting reliable rigs and scaffolds for plants and factories, loading docks, mines and ports, and construction and demolition sites. Complete with extensive coverage of relevant OSHA regulations plus the author's own expert advice on safe practices, this definitive guide shows you how to select and use: rigging tools--fiber and wire-strand rope, slings and hitches, end attachments and fittings, and blocks, sheaves, reeving, and drums-scaffolding and ladders--both manual and powered swinging and suspended scaffolds, wood and metal stationary scaffolds, specialized scaffolds, and portable ladders, rigging machinery--derricks and cranes, overhead hoists, personnel/material hoists, and helicopters, rigging accessories--jacks, rollers, and skids plus safety belts, lifelines, and nets.

B30.3 applies to “construction tower cranes” and “permanently mounted tower cranes” that are powered by electric motors or internal combustion engines and that adjust their operating radius by means of a luffing boom mechanism, a trolley traversing a horizontal jib, or a combination of the two. The cranes may be mounted on “fixed bases” or “traveling bases” and may have tower and supporting structure arrangements that permit the crane to climb in a structure being built or that permits’ increasing the crane’s tower height as the structure rises. Variations of the above physical characteristics that provide the same fundamental operating characteristics are included in the scope of this Volume however, the requirements of this Volume are only applicable to the cranes within this scope when they are used in lifting operations. Mobile cranes configured with tower attachments (refer to ASME B30.5) and self-erecting tower cranes (refer to ASME B30.29) are not within the scope of this Volume.

B30.4 applies to the construction, installation, operation, inspection, and maintenance of electric motor or internal-combustion engine powred portal and pedestal cranes, that adjust operating radius by means of a boom luffing mechanism or by means of a trolley traversing a horizontal boom, that may be mounted on a fixed or traveling base, and to any variation thereof that retain the same fundamental characteristics. This standard applies only to portal and pedestal cranes utilizing a drum and wire rope for hoisting and which are used for hoisting work. The requirements for tower cranes (refer to ASME B30.3), telescopic boom cranes (refer to ASME B30.5), and knuckleboom cranes (refer to ASME B30.22) are not included in this standard.

ASME B30.5 is widely respected and applied throughout the building and construction industry. It addresses crawler cranes, locomotive cranes, wheel-mounted cranes, and any variations thereof that retain the same fundamental characteristics and are powered by internal combustion engines or electric motors. The scope of this Safety Standard includes only cranes of the above types that are powered by internal combustion engines or electric motors. Side boom tractors and cranes designed for railway and automobile wreck clearance, digger derricks, cranes manufactured specifically for, or when used for, energized electrical line service, knuckle boom, trolley boom cranes, and cranes having a maximum rated capacity of one ton or less are excluded.
