Question: A technician is installing a new final drive assembly on an excavator. The assembly weighs approximately 250 kg. Which lifting equipment and procedure should be used to safely position the final drive?
Answer options: ✅ A chain fall or hoist attached to an overhead crane, ensuring proper rigging and load balance.
- A floor jack and a pry bar, with assistance from another technician.
- A forklift with extended forks, carefully maneuvering the assembly into place.
- Using a manual hand truck with straps to slide the assembly off a pallet.
Correct answer: A chain fall or hoist attached to an overhead crane, ensuring proper rigging and load balance.
Explanation: For heavy and awkward components like a final drive assembly, an overhead crane with a properly rated chain fall or hoist offers the safest and most controlled method for lifting and precise positioning. Floor jacks, pry bars, or manual hand trucks are inadequate and unsafe for this weight and precision requirement. Forklifts would struggle with the precise positioning needed for installation.
