Fixed/Swing Crane Operations Practice Test 2026 – Complete Exam Prep

Pins should be installed so they can be reached from the outside of the boom. This placement keeps the pin accessible for removal and inspection without crawling into confined spaces or dismantling protective covers, which makes changing or reconfiguring the boom quicker and safer. If a pin were installed from inside the boom, you’d have to enter the boom to remove it, which is risky and impractical. Installing from other locations, like the base or above the crane, would complicate access and hinder safe, easy removal. Keeping the pins on the exterior ensures straightforward maintenance and a safer operation.
