ASME B30.5 pdf download.Mobile and Locomotive Cranes.
Within the general scope defined in Section 1, American National Standard B30.5 applies to crawler cranes, locomotive cranes, wheel-mounted cranes, and any variations thereof that retain the same fundamental characteristics. The scope includes only cranes of the above types that are basically 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.
Special adaptions to the general types of machines covered by this Wlurne, where applicable, fall under this scope.
Some basic machine types within this scope are used alternatively for lifting service and for applications not considered to be lifting service. All of the requirements of this Volume are applicable to such machines when used for lifting service. However, at a minimum, Section 5-1.11, Chapter 5-2, and Section 5-3.1 of this Volume apply to machines when used in other than lifting service.
SECTiON 5-0.2: DEFiNITIONS
5-0.2.1 Types of Mobile and Locomotive Cranes
comrncrcwl truck-nrounh’d eraw a crane consisting of a rotating superstructure (center post or turntable), boom, operating machinery, and one or more operator’s stations mounted on a frame attached to a commercial truck chassis, usually retaining a payload hauling capability whose power source usually powers the crane. Its function is to lift, lower, and swing loads at various radii (see Figs. 5-0.2.1-1 and 5-0.2.1-2).
crawlcr crane: a crane consisting of a rotating superstructure with a power plant, operating machinery, and boom, mounted on a base and equipped with crawler treads for travel. Its function is to lift, lower, and swing loads at various radii (see Figs. 5-0.2.1-3 and 5-0.2.1-4).
(I) tires for recommended inflation pressure
5-2.1.3 Periodic Inspection
Complete inspections of the crane shall be performed by a qualified person at intervals as generally defined in para. 5-2.1.1(b)(2), depending on the crane’s activity severity of service, and environment, or as specifically indicated below. These inspections shall include the requirenwnts of para. 5-2.1.2 and items such as the following. Any deficiencies shall be examined and determination made as to whether they constitute a hazard.
(a) deformed, cracked, or corroded members in the crane structure and entire boom
(b) loose bolts or rivets
(C) cracked or worn sheaves and drums
(d) worn, cracked, or distorted parts such as pins, bearings, shafts, gears, rollers, and locking devices
(e) excessive wear on brake and clutch system parts, linings, pawls, and rachets
(f) any significant inaccuracies of operational aids Irefer to para. 5-2.1.o(b)J
(g) lack of performance and compliance with safety requirements of gasoline, diesel, electric, or other power plants
(h) excessive wear of chain drive sprockets and excessive chain stretch
(i) cracked crane hooks
(j) malfunctioning travel steering, braking, and locking devices
(k) excessively worn or damaged tires
(1) hydraulic and pneumatic hose, Fittings, and tubing (1) evidence of leakage at the surface of the flexible
hose or its junction with the metal and couplings.
(2) blistering or abnormal deformation of the outer covering of the hydraulic or pneumatic hose.
(3) leakage at threaded or clamped joints that cannot be eliminated by normal tightening or recommended procedures.
(4) evidence of excessive abrasion or scrubbing on the outer surface of a hose, rigid tube, or fitting. Means shall be taken to eliminate the interference of elements in contact or otherwise protect the components.
