Six Key Techniques to Extend the Service Life of Four Post Car Lifts


As a core equipment in auto repair shops, the service life of four post car lifts directly impacts maintenance efficiency and operational costs. Through scientific maintenance methods, the equipment's lifespan can be significantly extended. Below are six proven practical techniques:


1. Standardized Daily Operation

  1. Check platform levelness before each use to avoid uneven load distribution

  2. Ensure the vehicle's center of gravity is centered during lifting; strictly prohibit overloading (recommend maintaining 20% margin)

  3. Always engage safety locks after lifting to prevent hydraulic failure


2. Hydraulic System Maintenance
• Monthly oil level checks using ISO VG46 anti-wear hydraulic oil
• Replace hydraulic oil every 2,000 hours or annually (drain old oil first)
• Immediately replace leaking hoses to prevent contaminants from entering the system


3. Key Component Lubrication

Use lithium-based grease for regular maintenance:

  • Chains/wire ropes: Lubricate every 50 hours

  • Sliders/rollers: Weekly lubrication

  • Column guide rails: Clean monthly and apply dedicated guide rail oil


4. Electrical System Protection

  1. Install surge protectors to prevent voltage fluctuations

  2. Weekly sensitivity checks on limit switches

  3. Keep control boxes dry to avoid moisture-induced corrosion


5. Structural Component Maintenance
• Quarterly inspections for cracks in welded joints
• Promptly repair damaged anti-rust paint (recommend epoxy primer + polyurethane topcoat)
• Regularly adjust column verticality (deviation ≤2mm/m)


6. Environmental Management

  • Maintain dry working conditions (relative humidity ≤70%)

  • Avoid keeping four post car lifts at maximum height for extended periods

  • Preheat hydraulic systems to ≥15°C in winter before use


Special Reminder: Maintain a service log to record each maintenance session, replaced parts, and abnormalities. If abnormal noises occur or speed decreases by over 20%, immediately shut down for inspection.

By implementing these measures, the average service life of four post car lifts can be extended from 5-7 years to over 10 years while reducing failure rates by 60%. Remember: Preventive maintenance costs are always lower than breakdown repairs.
