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 the following items, if applicable, on
				cranes for sound physical condition and that they are functional within the
				manufacturer's recommendations (not including removal of inspection covers):
(a) For cranes that telescope the internal
				tower by a climbing frame, the climbing mechanism is structurally sound; is
				free of cracks, distortion, excessive wear or corrosion; operates within the
				manufacturer's specifications;
(b)
				Structural bolts are tightened;
(c)
				All control and drive mechanisms for interfering with proper operation and for
				excessive wear or contamination by lubricants or other foreign
				matter;
(d) Motion limiting devices
				for proper operation with the crane unloaded; each motion should be inched into
				its limiting device by carefully running at slow speed;
(e) Load limiting devices for proper
				operation and accuracy of settings;
(f) Air, hydraulic, and other pressurized
				lines for deterioration or leakage, particularly those which flex in normal
				operation;
(g) Hydraulic system for
				proper fluid level;
(h) Hydraulic,
				pneumatic and other pressurized hoses, fittings and tubing, as follows:
(i) Flexible hose or its junction with the
				fittings for indications of leaks.
(ii) Threaded or clamped joints for
				leaks.
(iii) Outer covering of the
				hose for blistering, abnormal deformation or other signs of failure/impending
				failure.
(iv) Outer surface of a
				hose, rigid tube, or fitting for indications of excessive abrasion or
				scrubbing;
(i) Hydraulic
				and pneumatic pumps and motors, as follows:
(i) Performance indicators: Unusual noises or
				vibration, low operating speed.
(ii) Loose bolts or fasteners.
(iii) Shaft seals and joints between pump
				sections for leaks;
(j)
				Hydraulic and pneumatic cylinders, as follows:
(i) Drifting.
(ii) Rod seals and welded joints for
				leaks.
(iii) Cylinder rods for
				scores, nicks and dents.
(iv) Case
				(barrel) for significant dents;
(k) Electrical components for malfunctioning,
				signs of apparent excessive deterioration, dirt or moisture accumulation,
				wiring for cracked or split insulation, and loose or corroded terminations;
(l) Ensure crane is grounded per
				manufacturer's specifications;
(m)
				Hooks and safety latches for deformation, cracks, excessive wear, or damage
				such as from chemicals or heat;
(n)
				Crane structure (including the boom, jib and counter jib):
(i) Structural members: Deformed, cracked, or
				significantly corroded.
(ii) Bolts,
				rivets and other fasteners: Loose, failed or significantly corroded.
(iii) Welds for cracks;
(o) Cracked or worn sheaves and
				drums;
(p) Worn, cracked, or
				distorted parts such as pins, bearings, shafts, gears, rollers, locking and
				clamping devices, sprockets, and drive chains or belts;
(q) Excessive wear on brake and clutch system
				parts, linings, pawls, and ratchets;
(r) Load, wind, and other indicators for
				inaccuracies outside the tolerances recommended by the manufacturer;
(s) A legible and applicable operator's
				manual and load chart is in the operator's station;
(t) Crane cleanliness and housekeeping.
				Inspect for trash, oil, grease, debris or excessive dirt on crane components
				and catwalks, if applicable;
(u) A
				portable fire extinguisher, with a basic minimum extinguishing rating of 10 BC
				must be installed in the cab or at the machinery housing;
(v) Ballast blocks in place and secured per
				manufacturer's recommendations;
(w)
				Wire rope reeving for compliance with the manufacturer's
				specifications;
(x) Wire rope, in
				accordance with WAC
				296-155-53200(5);
(y) Safety devices and operational aids for
				proper operation (including significant inaccuracies);
(z) Legible warning labels and decals as
				required by the manufacturer;
(aa)
				Steps, ladders, handrails and guards are in safe and usable
				condition.
