296-56-60098. Examination and inspection of cranes and derricks
(1) You must carry out an examination in conjunction with each annual unit proof load test. The accredited person, or their authorized representative, must make a determination as to correction of deficiencies found. The examination must include the following: (Refer to WAC 296-56-60093(8) for definition of accredited person.)
(a) All functional operating mechanisms must be examined for improper function, maladjustment, and excessive component wear, with particular attention to sheaves, pins, and drums. The examinations must include operation with partial load, in which all functions and movements, including maximum possible rotation in both directions, are checked.
(b) All safety devices must be examined for malfunction.
(c) Lines, tanks, valves, drains, pumps, and other parts of air or hydraulic systems must be examined for deterioration or leakage.
(d) Rope reeving must comply with the manufacturer's recommendations.
(e) Deformed, cracked, or excessively corroded members in crane structure and boom must be repaired or replaced as necessary.
(f) Loose bolts, rivets, or other connections must be corrected.
(g) Worn, cracked, or distorted parts affecting safe operation must be corrected.
(h) All brakes, used to control the load, boom or travel of the crane, must be tested. Air, hydraulic, or electrically operated brakes must be of such design as to set and stop the load if the source of power fails.
(i) Brake and clutch system parts, linings, pawls, and ratchets must be examined for excessive wear and free operation.
(j) Load, boom angle, or other indicators must be checked over their full range. Defects in such indicators must be immediately corrected.
(k) Where used, clamshell buckets or other similar equipment, such as magnets, must be carefully examined in all respects, with particular attention to closing line wires and sheaves. The accredited person may supplement such examination by requesting any operational tests deemed appropriate.
(l) Careful examination of the 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, must be made.
(m) All platforms, steps and footwalks located on cranes where workers are exposed to the hazard of slipping must be of a nonslip material. Wire rope used for railings on cranes must be kept taut at all times.
|Note:||In critical areas such as footwalks along booms, a grating material should be used.|
(n) No counterweights in excess weight of the manufacturer's specifications must be fitted or used.
(o) Such other examination or supplemental functional tests must be made as may be deemed necessary by the accredited person under the circumstances.
(2) You must meet the following requirements for wire rope:
(a) All wire rope must be inspected at least once a month, dependent upon conditions to which the wire ropes are subjected, and at intervals not exceeding a twelve-month period. Records of inspection of wire rope must be kept and must be available to the department of labor and industries representative. Records must be kept for one year. Refer to the general safety and health standards, WAC 296-24-24013.
(b) Wire rope must not be used if in any length of eight diameters, the total number of visible broken wires exceeds ten percent of the total number of wires, or if the rope shows other signs of excessive wear, corrosion, or defect. Particular attention must be given to the condition of those sections of wire rope adjacent to any terminal connections, those sections exposed to abnormal wear, and those sections not normally exposed for examination.
(c) Documentation available for inspection must include wire rope test certificates relating to any replacements made since the last unit test or annual examination as required.
(d) Wire rope and replacement wire rope must be of the same size, same or better grade, and same construction as originally furnished by the equipment manufacturer or contemplated in the design, unless otherwise recommended by the equipment or wire rope manufacturer due to actual working conditions. In the absence of specific requirements, wire rope must be of a size and construction suitable for the purpose, and must have the capacity to handle five times the heaviest expected load, verified by wire rope test certificate.
(e) Wire rope in use on equipment previously constructed and prior to initial certification of said equipment must not be required to be tested but must be subject to thorough examination at the time of initial certification of the equipment.
(3) You must meet the following requirements for accessory components:
(a) Container spreader bar twist locks must be carefully examined periodically and at the time of annual examination and inspection. Cracked or deformed hooks must be discarded immediately and not reused.
(b) Crane hooks and container spreader bar twist lock. Magnetic particle or other suitable crack detecting inspection must be performed at least once each year. When testing by X ray, the pertinent provisions of the Nuclear Regulatory Commission's standards for protection against radiation, relating to protection against occupational radiation exposure, must apply.
(4) You must make sure, in the event that heat treatment of any loose gear is recommended by the manufacturer, the latest heat treatment certificate attesting to compliance with the manufacturer's specifications must be part of the available documentation. Heat treatment must be carried out in accordance with the specifications of the manufacturer by persons competent to perform such work.
(5) You must make sure replacement parts are of equal or better quality than the original equipment and suitable for the purpose. Repairs or modifications must be such as to render the equipment equal to or better than the original construction or design.
(6) You must make sure, in cases of foreign manufactured cranes, there is an owner's warranty that the design is adequate for the intended use. The warranty must be based on a thorough examination of the design specifications by a registered professional engineer familiar with the equipment.
(7) You must make sure the certifications required by this section are performed in accordance with WAC 296-56-60093 by persons accredited by the assistant director of DOSH.
(8) You must make sure the marine terminal material handling devices listed below are certified in the following manner:
(a) Each crane and derrick must be tested and examined as a unit annually. A copy of the certificate of tests and examinations must be posted in the crane operator's cab.
(b) Bulk cargo spouts and suckers, together with any portable extensions and rigging or outriggers supporting them vertically, must be examined annually. Certificates attesting to the required examination must be made readily available for inspection.
(c) Vertical pocket or bucket conveyors such as banana, sugar, and grain marine legs (other than those within a grain elevator structure) used within a marine terminal facility must be examined annually.
