(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.

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.
