Current through Register Vol. 24-14, July 15, 2024
(1) After it is
				determined that the crane configurations meet the criteria in WAC
				296-155-53200, the accredited
				crane certifier must visually inspect, without disassembly, and if applicable,
				the following items on overhead and bridge cranes for sound physical condition
				and that they are functional within the manufacturer's recommendations (not
				including removal of inspection covers):
(a)
Controllers.
Control mechanisms for interfering with proper
				operation. Control and drive mechanisms for apparent excessive wear of
				components and contamination by lubricants, water or other foreign
				matter;
(b)
Load
				hooks.
Inspect for damage wear to hook nuts, safety latch and hook
				swivel. Check for deformation, cracks, excessive wear, or damage such as from
				chemicals or heat. Inspect blocks for wear to sheaves, check plates, and pins.
				Check for loose pins, bolts and guards;
(c)
Sheaves and bearings.
Check
				all sheaves and bearings for lubrication and excessive wear. Ensure sheaves
				turn freely. Check sheave pin locking device;
(d)
Structural supports.
Inspect
				for damage or bent girders, girder seat top plate, diaphragms and structural
				column connections. Check for loose bolts or rivets, and cracks;
(e)
Bridge inspection.
(i) Check complete structure for broken,
				cracked, damaged, missing, or corroded parts and members.
(ii) Handrails, walkways, and ladders.
				Inspect for loose, missing, bent, deteriorated or misaligned members, loose
				bolts, rivets, broken welds and hangers;
(f)
Brackets.
Check for cracked
				or corroded welds, missing or loose bolts, bent or cracked brackets;
(g)
End stops.
Inspect for
				damaged wheels, broken welds, loose or missing bolts, damaged bumpers, missing
				pins or damaged plates;
(h)
Runway rail and clamps.
Inspect for loose, broken or missing
				clamps. Check the condition of railhead and side wear, rail splice plates
				and/or welds, rail gaps and associated bolts, wedges, connectors and rail
				switches;
(i)
Crane
				alignment.
Inspect for proper bridge end float while crane travels in
				both directions on runway. Check all corner connections for rust, shear marks,
				loose or missing bolts, nuts and washers. Inspect square marks and legibility
				of dimension;
(j)
Wheels and
				bearings.
Inspect wheels for wear, flat spots, chips, flange wear,
				cracks, loose axle pins, or securing devices. Check bearing clearance, chatter,
				loose bearing caps and lubrication;
(k)
Trolley.
Check for loose,
				missing, broken or bent members. Inspect for loose, faulty or missing coupling
				guards. Check for broken, loose or missing axle pins. Inspect for axle pins
				displaying excessive wear;
(l)
Trolley rail.
Inspect for bent or damaged members, loose bolts,
				rivets, guards, trolley rail clamps, end stops and broken welds. Check
				condition of rail head and side wear, rail splice plates and/or welds and rail
				gaps;
(m)
Trolley
				conductors.
Inspect insulators and clamps, loose connectors, bent,
				pitted or damaged wires or collectors;
(n)
Shafts, couplings, and
				bearings.
Inspect shafts for vibration, cuts and nicks, loose or worn
				keyways and misalignment. Check coupling for wear, loose bolts or keys and
				misalignment. Inspect bearing for clearance, chatter, loose bearing caps and
				proper lubrication;
(o)
Gearing.
Inspect gears for worn teeth, cracked teeth, superficial
				root cracks, pitting, unusual indentation or wear marks, full contact or end
				loading, loose set screws and keys. Check guards and covers. Inspect gear cases
				for excessive noise and vibration, proper lubrication and leaking;
(p)
Wire rope and drum.
Inspect
				wire rope for damage. Check rope clip fittings and associated mounting hardware
				for wear and damage. Inspect drum grooves for excessive wear. Inspect drum
				pedestal and bearing condition. Check for cracks in drum;
(q)
Electrical items.
Check all
				contacts for proper alignment and evidence of excess heating or unusual arcing.
				Inspect all coils, contact leads, shunts and wires, fuses or overload devices
				for loose connections and evidence of overheating. Inspect panel board and arc
				shields for cracks, loose bolts, dirt and moisture. Check panel marking for
				legibility. Inspect speed control resistors for damaged insulation, cracked or
				broken grids, loose connections, bolts and brackets;
(r)
Motor.
Inspect for damage,
				bearing noise, vibration and lubrication, spark and cleanliness of commutator
				and brush wear, loose hold down bolts and motor brackets. Inspect commutator or
				slip rings for evidence of overheating and brush sparking. Inspect motor leads
				and insulators, damaged or deteriorated insulation and loose connections.
				Inspect brush holder for proper clearance to commutator or slip rings, and
				freedom of brushes;
(s)
Brakes.
Inspect for wear in linkage, pins and cams, weakness of
				springs, wear and condition of lining, smoothness of the drum, heat check crack
				and clearance between drum or disk. Inspect for improper solenoid air gap;
				evidence of overheating; damaged brass, and loose core laminations; delay or
				restriction in opening of brakes;
(t)
Hoist brakes.
Inspect for
				wear in linkage, pins and cams, weakness of springs, wear and condition of
				lining, smoothness of drum, heat check cracks and clearance between drum or
				disk. Inspect for improper solenoid air gap; evidence of overheating; damaged
				brass, and loose core laminations; delay or restriction in opening of
				brakes;
(u)
Limit
				switches.
Remove covers and inspect all electrical and mechanical
				components for malfunction including contacts, springs, ratchets, pins, arm and
				insulators, rollers, cams and dogs. Inspect cover gaskets, counterweight
				guides. Check all securing bolts and guards. Check for weather or moisture
				damage. Check for proper operation;
(v)
Crane cleanliness and
				housekeeping.
Inspect for trash, oil, grease, debris or excessive dirt
				on crane components and catwalks, if applicable;
(w)
Operation of crane controls.
Operate all crane controls and check for proper operation. Check for smooth and
				regular motions without abnormal sensations, hesitations, binding, vibrations,
				shimmy, or irregularity;
(x)
Warning device/fire protection.
Inspect for proper operation of
				sirens, horns, bells and lights. Check switches and inspect wiring and
				connections;
(y) A legible and
				applicable operator's manual and load chart is in the operator's cab or
				station;
(z) A portable fire
				extinguisher, with a basic minimum extinguishing rating of 10 BC must be
				installed in the cab or at the machinery housing.
