Current through Register Vol. 48, No. 38, September 20, 2024
a) Wire rope
used on amusement rides and amusement attractions shall be thoroughly examined
periodically per amusement ride or amusement attraction manufacturer's
specifications.
b) Wire rope found
damaged shall be replaced with new wire rope conforming to specifications set
forth by the amusement ride or amusement attraction manufacturer. Any of the
following conditions shall be cause for wire rope replacement:
1) In running ropes, 6 randomly distributed
broken wires in one rope lay, or three broken wires in one strand in one rope
lay. A rope lay being the length along the rope required for one strand to make
one revolution around the rope;
2)
In pendants or standing ropes (ropes bearing the entire load or subjected to
constant pressure or shock loading), evidence of more than one broken wire in
one rope lay;
3) Abrasion,
scrubbing or peening causing loss of more than 1/3 of the original diameter of
the outside wires;
4) Corrosion
which results in surface pitting on the wires;
5) Kinking, crushing, birdcaging, or other
damage resulting in distortion of the rope structure causing some members of
the rope structure carrying more load than others;
6) Heat damage;
7) Reduction from the normal diameter of the
wire rope of more than 3/64
inch for diameters up to and including 3/4 inch;
1/16 inch for diameters over
3/4 inch up to and including
11/18 inches;
3/32 inch for diameters over
11/18 inches up to 11/2
inches;
8) Any rust that cannot be
removed by wiping the wire rope with an oily rag or development of broken wires
in the vicinity of attachments. If this condition is localized in an operating
rope, the section in question may be eliminated by making a new attachment;
and
9) Wire ropes used to support,
suspend, bear or control forces and weights involved in the movement and
utilization of tubs, cars, chairs, seats, gondolas, other carriers, the sweeps,
or other supporting members of an amusement ride or amusement attraction shall
not be lengthened or repaired by splicing.
c) When using U-bolt clips, the U section of
each clip must contact the dead end or short end of the wire rope.
d) Mechanical devices, such as rollers, drums
or sheaves, shall not have any chipping, unequal wear, surface roughness or
deterioration in any area that contacts the wire rope.
