ASME B30.22-2016 pdf download.Articulating Boom Cranes.
SECTION 22-0.1: SCOPE OF B30.22 The scope includes cranes of the types described in para. 22-0.2.1 that are articulated by hydraulic cylinders and powered by internal combustion engines or electric motors and that are mounted on a mobile chassis or stationary installation. Articulating cranes equipped with a load hoist mechanism to broaden their versatility are covered by this Volume. Some basic machine types within this scope are con- vertible for excavating work and other uses not consid- ered to be lifting service. The requirements of this Volume are applicable only to such machines when used as lifting cranes. When cranes within the scope of this Volume are used for service other than lifting service, the manufacturer or (when not available from the manu- facturer) a qualified person shall establish the ratings, operating limitations, maintenance, testing, and inspec- tion requirements that apply during that use. Exemptions from this Volume include (a) units with a maximum rated capacity of 2,000 lb (907 kg) or less (b) units with booms constructed of nonconductive- type materials (c) units equipped withordesigned primarilyfor per- sonnel baskets, platforms, ladders, etc. (d) units when equipped with nonlifting attachments (e) units while used in forestry and logging applications (f) telescoping boom cranes that do not articulate (covered under ASME B30.5) (g) scrap and material handlers as defined in ASME B30.25 SECTION 22-0.2: DEFINITIONS 22-0.2.1 Mounting of Articulating Boom Cranes commercial truck-mounted: a crane, consistingofa rotating mast, mainframe or base, boom, and one or more opera- tor’s stations, such as ground controls (Fig. 22-0.2.1-1), top seat controls (Fig. 22-0.2.1-2), or remote controls 1 (Fig. 22-0.2.1-3), mounted on a frame attached to a com- mercial truck chassis, with or without a payload capabil- ity, whose power source may power the crane. The function is to lift, lower, and swing loads at various radii. crawler-mounted: a crane, consisting of a rotating mast, mainframe or base, operator’s station(s), and boom, mountedoncrawlertreads fortravel. Itmaybe equipped with a single control station or have separate stations for driving and operating. Its function is to lift, lower, and swing loads at various radii. See Fig. 22-0.2.1-4. stationary: a crane, consisting of a rotating mast, main- frame or base, and boom, mounted on a stationary struc- ture. The function is to lift, lower, and swing loads at various radii from a fixed center of rotation. See Fig. 22-0.2.1-5. trailer- or railcar-mounted: a crane, consisting of a rotating mast, mainframe or base, and boom, mounted on a trailer or railcar. The function is to lift, lower, and swing loads at various radii. See Figs. 22-0.2.1-6 and 22-0.2.1-7. traveling base-mounted: a crane, consisting of a rotating mast, boom, mainframe or base, and one or more opera- tor’s stations, mounted on a traveling base. The function is to lift, lower, and swing loads at various radii. See Fig. 22-0.2.1-8. wheel-mounted: a crane, consisting of a rotating mast, mainframe or base, operator’s station(s), and boom, mounted on commercial truck vehicle, a trailer, or an off-road vehicle equipped with axles and rubber-tired wheels. It may be equipped with a single control station or have separate stations for driving and operating. Its function is to lift, lower, and swing loads at various radii. See Figs. 22-0.2.1-1, 22-0.2.1-2, 22.0.2.1-3, 22.0.2.1-7, 22-0.2.1-8, and 22-0.2.1-9. 22-0.2.2 General Definitions accessory: a secondary part or assembly of parts that contributes to the overall function and usefulness of a crane.
(2) satisfactory completion of a written examina- tion covering operational characteristics, controls, and emergency control skills, such as response to fire, power line contact, loss of stability, or control malfunction, as well as characteristic and performance stability ques- tions appropriate to the crane type for which requalifica- tion is being sought (3) demonstrated ability to read, write, compre- hend, and use arithmetic and a load rating chart, in the language of the crane manufacturer’s operation and maintenance instruction materials (4) satisfactory completion of a combination writ- ten and verbal test on load rating chart usage that covers a selection of the configurations (the crane may be equipped to handle) for the crane type forwhich requali- fication is being sought (5) satisfactory completion of an operation test demonstrating proficiency in handling the specific crane type for which requalification is being sought, including both prestart and poststart inspections, maneuvering skills, shutdown, and securing procedures
