After all parts of a gantry crane have been assembled, the next step is to:

• A. Reeve and secure the main-load falls and runner or whip
• B. Inspect the hoist lines
• C. Install outriggers
• D. Erect the gantry in the high position

Answer: (A)

Reave and secure the main-load falls and the runner or whip right after assembly because the hoist ropes must be threaded correctly through the drum and all sheaves and then anchored so they cannot slip or unwind. Proper reeving ensures the rope sits in the correct grooves, winds smoothly as the trolley moves, and doesn’t derail or jam when you start operating the crane. Securing the ends prevents the rope from unspooling or snagging during initial movements, which protects both the equipment and the operator. Once the rope path is correct and the ends are secured, you can proceed with inspecting the lines and then other setup steps like stabilizing the gantry and positioning it as needed.
