Question: During a typical climb cycle for a top-slewing tower crane, which component is inserted AFTER the mast section is lifted into position by the crane's own hoist mechanism, but BEFORE the climbing frame is lowered and fixed?
Answer options: ✅ The mast bolts or pins to secure the newly added mast section.
- The counterweights, if they were removed for the climb.
- Additional lengths of the hoist rope.
- The operator's cab.
Correct answer: The mast bolts or pins to secure the newly added mast section.
Explanation: After the new mast section is hoisted into place and aligned within the climbing frame, the critical next step is to insert and secure the mast bolts or pins. This physically connects the new section to the existing mast structure, making it a stable part of the crane before the climbing frame can be moved. This is a key step in the CSA Z248 climb procedure.
