SECTION 22-0.1: SCOPE OF B30.22
The scope includes cranes of the types described inpara 22-0.2.1 that are articulated by hydraulic cylindersand powered by internal combustion engines or electricmotors and that are mounted on a mobile chassis orstationary installation. Articulating cranes equippedwith a load hoist mechanism to broaden their versatilityare covered by this Volume.
Some basic machine types within this scope are convertible for excavating work and other uses not consid-ered to be lifting service. The requirements of thisVolume are applicable only to such machines when usedas lifting cranes. When cranes within the scope of thisVolume are used for service other than lifting servicethe manufacturer or (when not available from the manu-facturer) a qualified person shall establish the ratingsoperating 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 1b(907 kg) or less
(b) units with booms constructed of nonconductivetype materials
(c) units equipped with or designed primarily for personnel baskets,platforms, ladders, etc.
(d) units when equipped with nonlifting attachments(e) units while used in forestry and loggingapplications
(f) telescoping boom cranes that do not articulate(covered under ASME B30.5)
(8) scrap and material handlers as defined inASME B30.25
SECTION 22-02: DEFINITIONS22-0.2.1 Mounting of Articulating Boom Cranescommercial truck-mounted: a crane, consisting of a rotatingmast, 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 (Fig.22-0.2.1-3), mounted on a frame attached to a commercial truck chassis, with or without a payload capability, whose power source may power the crane. Thefunction is to lift, lower, and swing loads at various radii.
crauler-mounted: a crane, consisting of a rotating mastmainframe or base, operator’s station(s), and boommounted on crawler treads for travel.Itmay be equippedwith a single control station or have separate stationsfor 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 atvarious radii from a fixed center of rotation.SeeFig.22-0.2.1-5.
trailer- or railcar-nounfed: a crane, consisting of a rotatingmast, mainframe or base, and boom, mounted on atrailer or railcar. The function is to lift, lower, and swingloads at various radii. See Figs.22-0.2.1-6 and 22-0.2.1-7.
traveling base-mnounted: a crane, consisting of a rotatingmast, boom, mainframe or base, and one or more operator’s stations, mounted on a traveling base. The functionis to lift, lower, and swing loads at various radii. SeeFig.22-0.2.1-8.
wheel-mnounfed: a crane, consisting of a rotating mast,mainframe or base,operator ‘s station(s),and boommounted on commercial truck vehicle, a trailer, or anoff-road vehicle equipped with axles and rubber-tiredwheels. It may be equipped with a single control stationor have separate stations for driving and operating. Itsfunction is to lift, lower, and swing loads at variousradii.See Figs.22-0.2.1-1,22-0.2,1-2,22.0.2.1-3,22.0.2.1-722-0.2.1-8,and 22-0.2.1-9.
22-0.2.2 General Definitionsaccessory: a secondary part or assembly of parts thatcontributes to the overall function and usefulness of acrane.
