Section 5:14A-9.31 - Wire rope

(a) Wire rope on amusement rides shall be thoroughly examined periodically. Wire rope found to be damaged shall be replaced with new rope of proper design and capacity as per the manufacturer's specifications. Any of the following conditions shall be cause for replacement:

1. In running ropes, six randomly distributed broken wires in one rope lay or three broken wires in one strand in one rope lay;

2. In pendants or standing ropes, evidence of more than one broken wire in one rope lay;

3. Any condition which causes the loss of more than one-third of the original diameter of the outside individual wires;

4. Severe corrosion;

5. Kinking, crushing, bird-caging, or other damage resulting in distortion of the rope structure;

6. Heat damage;

7. Reduction from normal diameter of more than 3/64 inch for diameters up to and including 3/4 inch, 1/16 inch for diameters, 7/8 inch to 1 1/8 inches, 3/32 inch for diameters 1 1/4 inches to l 1/2 inches;

8. Bird-caging or other distortion resulting in some members of the rope structure carrying more load than others; or

9. Noticeable rusting or development of broken wires in the vicinity of attachments. When this condition is localized in an operational rope, it may be eliminated by making a new attachment.

(b) 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 shall not be lengthened or repaired by splicing. In addition, these shall have a redundant support system capable of carrying the full load. Redundancy of the support system may also be accomplished with a design that includes a higher safety factor in the manufacture of the support system.

(c) Rides utilizing vehicles hanging or suspended from a wire rope shall relocate the vehicles on an annual basis as required by manufacturer's specifications.

(d) Previous fastening points shall be clearly marked for identification when disassembling.
