What maintenance tasks should be performed after a lift on the crane?

• A. Lubricate moving parts
• B. Inspect wire rope and sheaves
• C. Test safety devices
• D. All of the above

Answer: (D)

After a lift, it’s important to run through a quick but complete check of the crane’s condition to keep it safe and reliable for the next operation. Lubricating moving parts reduces friction and wear, helping components operate smoothly and last longer. Inspecting the wire rope and sheaves catches wear, fraying, corrosion, or misalignment that could lead to rope failure or uneven loading. Testing safety devices verifies that protective systems like brakes, limit switches, emergency stop, and load indicators respond correctly, preventing uncontrolled movement or overload. Since each of these checks addresses a different potential risk, performing all of them after a lift is the proper practice.
