Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-56 - Safety standards-Longshore, stevedore and waterfront related operations › Section 296-56-60098 - Examination and inspection of cranes and derricks

Current through Register Vol. 24-14, July 15, 2024
(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.
