Current through Register Vol. 54, No. 44, November 2, 2024
(a)
Maintenance program. The
owner of an amusement ride or amusement attraction shall implement a program of
maintenance, testing and inspection, based on manufacturer's recommendations,
providing for the duties and responsibilities necessary in the care of each
amusement ride or attraction. The maintenance program must include a checklist
to be made available to the person performing the regularly scheduled
maintenance. The maintenance program must include, the ASTM International F-24
Committee Standards for the operation, maintenance, testing and
inspections.
(b)
Electricity lock-out. A person performing maintenance or
repairs, or making an inspection, shall lock-out the electrical disconnect
switch when restoration of electrical power to an amusement ride or amusement
attraction could create a hazard to persons during the performance of
maintenance, repair, inspection or an emergency evacuation of persons, and
ensure that it remains locked out until restoration of power will not create a
hazard.
(c)
Identification
and rating plates. Manufacturers' identification information affixed
to the ride or attraction shall be maintained in a readily visible and legible
condition at all times to the inspector.
(d)
Wire rope.
(1) Wire rope shall be thoroughly examined.
Wire rope found to be damaged shall be replaced with a new rope of proper
design and capacity as set forth on the manufacturer's date tag. If failure of
the rope would affect safety of the ride or attraction and its passengers any
of the following conditions will be cause for rope replacement:
(i) In running ropes, six radomly distributed
broken wires in a rope lay, or four broken wires in one strand of a rope lay. A
rope lay is the length along the rope in which one stand makes a complete
revolution around the rope.
(ii) In
pendants or standing ropes-ropes bearing the entire load and subject to
constant pressure and surge shocks-evidence of more than one broken wire in one
rope lay.
(iii) Abrasion, scrubbing
or peening causing loss of more that 1/3 of the original diameter of the
outside individual wires.
(iv)
Severe corrosion.
(v) Kinking,
crushing, birdcaging or other damage resulting in distortion of the rope
structure.
(vi) Heat
damage.
(vii) Reduction from
nominal diameter of more than 6.0%. Marked reduction in diameter indicates
deterioration of the core resulting in lack of proper support for the load
carrying strands. Excessive rope stretch or elongation may be an indication of
internal deterioration.
(viii)
Bird-caging or other distortion resulting in some members of the rope structure
carrying more load than others.
(ix) Noticeable rusting or development of
broken wires in the vicinty of attachments. If the condition is localized in an
operating rope, the section in question can be eliminated by making new
attachment. This may be done rather than replacing the entire rope.
(2) Wire ropes used to support,
suspend, bear, or control forces and weights involved in the movement and
utilization of tubs, cars, chairs, sets, other carriers, the sweeps, or other
supporting members of a ride or attraction may not be lengthened or repaired by
splicing.
(3) Mechanical devices
that brake, control, or come in contact with wire rope, such as rollers, drums
and sheaves shall be examined to ensure cleanliness and safe condition.
Mechanical devices with broken chips, undue roughness or uneven wear shall be
replaced immediately.
(e)
Wood components. Footings, splices, uprights, track timers,
ledgers, sills, laps, bracing, flooring and all other wood components of rides,
attractions and structures shall be inspected for deterioration, cracks or
fractures. Emphasis shall be given to insuring tight nails, bolts, lag bolts
and other fasteners. When wood piling requires replacement, ground level
concrete piers shall be used. Wood members found to be defective shall be
removed and replaced with material of equal or greater strength and capacity.
Repairs and replacements to fixed roller coasters shall be made in accordance
with the recommendations of the manufacturer.
(f)
Articulations and
bearings.
(1) The articulating
pinions, frames, sweeps, eccentrics and other mechanical members shall be
inspected for wear, out-of-round, cracks and other signs of deterioration, and
shall be kept in good repair.
(2)
Main center spindles shall be tested by nondestructive methods according to the
manufacturer's specifications. Test results must list the date of the test,
name of the ride owner and serial number or identification number of the
device.
(3) Bearing surfaces, ball
joints and other single or multiple direction mechanical surfaces shall be kept
well lubricated, clean and inspected for out-of-round or out-of-spherical and
shall be kept in good repair.
(4)
Gear alignment and gear drives shall be kept in good repair.
(5) Motor wiring, general service circuitry,
decorative wiring and festoon wiring shall be inspected for signs of
deterioration such as cracking. Secure tape repairs may be used; however, use
of tape repairs shall be kept to a minimum. Wire clips on articulating devices
shall be kept in good repair, and particular attention shall be paid to wires
at elbows and at the end of articulating devices during inspections.
(6) Retaining, restraining and containing
devices shall be inspected to insure they can continuously fulfill their
function. Worn and damaged areas shall be repaired immediately or be
immediately replaced.
(7) The
hydraulic system shall be checked for leaks, damaged pipes and worn or
deteriorated hoses.
(8) A record of
each inspection, test and maintenance shall be made immediately upon completion
of the inspection/test and indicate those components subjected to special
examination, such as X-ray, liquid penetrant, magnetic particle or ultrasonic
testing and the dates the examinations were performed. The record must also
include breakdowns or repairs and violations of this chapter with action taken
to rectify the violation. The record shall be kept and made available to the
Department and qualified inspector for at least 3 years.
