What are the key safety steps when lifting a heavy engine or bus component with a jack and stands?

• A. Use rated equipment, place on a level surface, engage wheel chocks, use jack stands at approved points, never work under a component supported only by a jack
• B. Use makeshift supports
• C. Work underneath while supported by a jack
• D. Skip wheel chocks

Answer: (A)

Safely lifting a heavy engine or bus component relies on using properly rated equipment, a stable and level workspace, and solid support at designated points. Start by ensuring the surface is level and placing wheel chocks on the wheels that remain in contact with the ground to prevent any movement. Use a jack and stands that are rated for the weight you’re lifting, and position the stands under manufacturer-approved lifting points or structural areas that can bear the load without damage. After the component is safely lifted, lower it onto the stands and remove the jack. Never work under a load that’s only supported by a jack, because hydraulic jacks can fail or slowly descend, risking a dangerous collapse. These precautions keep the setup secure and protect you during the job.
