Question: A crane operator observes that the hoist rope on their mobile crane has three broken wires in one lay, within a section of rope that passes over a sheave. According to CSA Z150, what action should the operator take?
Answer options:
- Continue operating the crane, but reduce the load by 25%. ✅ Tag out the crane, discontinue use, and have the rope inspected by a qualified person.
- Mark the section of rope with tape and re-inspect it at the end of the shift.
- Request a new hoist rope be ordered for replacement within the next month.
Correct answer: Tag out the crane, discontinue use, and have the rope inspected by a qualified person.
Explanation: CSA Z150 specifies that if a running rope has three or more broken wires in one lay in an operating rope that passes over sheaves, the rope must be immediately removed from service. Reducing the load, re-inspecting later, or delaying replacement are all unsafe practices.
