Question: A crane's hoist line is a 19x7 rotation resistant wire rope. During a comprehensive inspection, how many broken wires are allowed in one rope lay of a rotating rope before it must be removed from service according to CSA Z150?
Answer options:
- Two randomly distributed broken wires in one rope lay. ✅ Four randomly distributed broken wires in one rope lay.
- Six randomly distributed broken wires in one rope lay.
- One randomly distributed broken wire in one rope lay.
Correct answer: Four randomly distributed broken wires in one rope lay.
Explanation: CSA Z150, Clause 5.2.2.1 (d), specifies stricter retirement criteria for rotation-resistant wire ropes compared to regular non-rotating ropes. For rotation-resistant ropes, the limit is four randomly distributed broken wires in one rope lay or two randomly distributed broken wires in one strand in one lay. The complex construction of these ropes makes internal wire breaks more critical and harder to detect, thus requiring a lower tolerance for external broken wires.
