§1613.6. Inspections - Annual/Comprehensive.

(a) At least every 12 months the equipment shall be inspected by a certificating agency in accordance with Section 1613.4 (Daily/each shift) except that the corrective actions set forth in Sections 1613.4, 1613.5 and 1613.6 shall apply in place of the corrective action required by Sections 1613.2 and 1613.3.

(b) In addition, at least every 12 months, equipment shall be inspected by a certificating agency. Disassembly is required, as necessary, to complete the inspection; however, whenever it is practical and advisable to avoid disassembly of equipment, removal of pins, etc., examination of structure or parts by electronic, ultrasonic, or other nondestructive methods shall be carried out. The equipment shall be inspected for all of the following:

(1) Equipment structure (including the boom and, if equipped, the jib):

(A) Structural members: Deformed, cracked, or significantly corroded.

(B) Bolts, rivets and other fasteners: loose, failed or significantly corroded.

(C) Welds for cracks.

(D) Junction areas of removable boom sections, particularly for proper seating, cracks, deformities, or other defects in securing bolts and in the vicinity of such bolts.

(2) All functional operating mechanisms for improper function, maladjustment, and excessive component wear, with particular attention to the following:

(A) Sheaves and drums for cracks or significant wear.

(B) Parts such as pins, bearings, shafts, gears, rollers and locking devices for distortion, cracks or significant wear.

NOTE: This shall include operation with partial load, in which all functions and movements, including, where applicable, maximum possible rotation in both directions, are performed.

(3) Excessive wear on and free operation of brake and clutch system parts, linings, pawls, and ratchets.

(4) Safety devices and operational aids for proper operation (including significant inaccuracies).

(5) Gasoline, diesel, electric, or other power plants for safety-related problems (such as leaking exhaust and emergency shut-down feature) and conditions, and proper operation.

(6) Chains and chain drive sprockets for excessive wear of sprockets and excessive chain stretch.

(7) Travel steering, brakes, and locking devices, for proper operation.

(8) Tires for damage or excessive wear.

(9) Hydraulic, pneumatic and other pressurized hoses, fittings and tubing, as follows:

(A) Flexible hose or its junction with the fittings for indications of leaks.

(B) Threaded or clamped joints for leaks.

(C) Outer covering of the hose for blistering, abnormal deformation or other signs of failure/impending failure.

(D) Outer surface of a hose, rigid tube, or fitting for indications of excessive abrasion or scrubbing.

(10) Hydraulic and pneumatic pumps and motors, as follows:

(A) Performance indicators: Unusual noises or vibration, low operating speed, excessive heating of the fluid, low pressure.

(B) Loose bolts or fasteners.

(C) Shaft seals and joints between pump sections for leaks.

(11) Hydraulic and pneumatic valves, as follows:

(A) Spools: Sticking, improper return to neutral, and leaks.

(B) Leaks.

(C) Valve housing cracks.

(D) Relief valves: Failure to reach correct pressure (if there is a manufacturer procedure for checking pressure, it shall be followed).

(12) Hydraulic and pneumatic cylinders, as follows:

(A) Drifting caused by fluid leaking across the piston.

(B) Rod seals and welded joints for leaks.

(C) Cylinder rods for scores, nicks, or dents.

(D) Case (barrel) for significant dents.

(E) Rod eyes and connecting joints: Loose or deformed.

(13) Outrigger or stabilizer pads/floats for excessive wear or cracks.

(14) Slider pads for excessive wear or cracks

(15) Electrical components and wiring for cracked or split insulation and loose or corroded terminations.

(16) Warning labels and decals originally supplied with the equipment by the manufacturer or otherwise required under this standard: Missing or unreadable.

(17) Originally equipped operator seat (or equivalent): Missing or unserviceable.

(18) Originally equipped steps, ladders, handrails, guards: Missing, or in unusable/unsafe condition.

(19) Load, boom angle, or other indicators shall be checked for any inaccuracy.

(20) Loose gear components (i.e. hooks, etc.), including wire rope and wire rope terminals and connections, with particular attention to sections of wire rope exposed to abnormal wear and sections not normally exposed for examination.

(A) Crane hooks with cracks or with deformation of throat opening more than 15 percent in excess of normal opening or more than 10 degree twist from plane of unbent hook shall be removed from service.

(21) Rope reeving for compliance with certified agent's recommendations.

(22) It shall be ascertained that no counterweights in excess of the certified agent's specifications are fitted.

(23) Such other examinations deemed necessary under the circumstances.

(c) This inspection shall include functional testing to determine that the equipment as configured in the inspection is functioning properly.

(d) If any deficiency is identified, an immediate determination shall be made by the certificating agency as to whether the deficiency constitutes a safety hazard or, though not yet a safety hazard, needs to be monitored in the periodic inspections.

(e) If the certificating agency determines that a deficiency is a safety hazard, the equipment shall be taken out of service until it has been corrected, except when temporary alternative measures are implemented as specified in Section 1615.2(d) or Section 1619.1(e). See Section 1616.1.

(f) If the certificating agency determines that, though not presently a safety hazard, the deficiency needs to be monitored, the employer shall ensure that the deficiency is checked in the periodic inspections.

(g) Documentation of annual/comprehensive inspection.

(1) The following information shall be documented, maintained, and retained for a minimum of 12 months, by the employer that conducts the inspection:

(A) The items checked and the results of the inspection.

(B) The name and signature of the person who conducted the inspection and the date.

Exception: Annual/Comprehensive inspections of Section 1613.6 may be performed by a qualified person for cranes not exceeding 3 tons rated capacity.

(2) Records required for crane certification shall be maintained in accordance with the provisions of Title 8 CCR Section 344.80.
