How many steps are required to perform the crane function check?

• A. 4 steps
• B. 5 steps
• C. 6 steps
• D. 7 steps

Answer: (C)

The six-step crane function check is a compact, complete sequence designed to verify every critical control and safety feature before lifting. It starts by ensuring the crane is powered up and the control circuits are ready. Next, you test each motion—boom movement, hoist, and slewing—in a controlled, safe condition to confirm the operator has full and correct control. Then you verify that travel and direction responses work as expected in both directions. After that, you check safety devices such as limit switches, interlocks, and the emergency stop to ensure they engage properly. The fifth step focuses on braking performance and the load-indicating or overload warning systems, ensuring they function correctly. Finally, you perform a quick final sweep for any abnormal indicators, leaks, or unusual noises and reset the controls. This six-part structure ensures nothing essential is left unchecked, which is why six steps is the standard.
