What is the pre-use checks list and maintenance process for a two-post vehicle hoist?

Daily Checks (Before Use)

1. Visual Inspection:

   • Check for hydraulic leaks around the cylinders, hoses, and connections.

   • Inspect lifting arms, pads, and adapters for cracks, wear, or damage.

   • Ensure the floor is clean, dry, and free of oil or debris.

2. Functional Tests:

   • Test the safety locks/latches to confirm they engage and disengage smoothly.

   • Verify the emergency stop button works immediately when pressed.

   • Operate the lift empty to ensure smooth ascent/descent.

3. Positioning:

   • Ensure the vehicle’s center of gravity aligns with the lift’s posts (refer to the lift’s manual for weight limits).

   • Confirm arm placement matches the vehicle’s lift points (e.g., pinch welds, frame rails).

Weekly Checks

1. Lubrication:

   • Grease all pivot points, sleeves, and sliding components (e.g., carriage rails).

2. Structural Inspection:

   • Tighten anchor bolts securing the lift to the floor.

   • Check for cracks or corrosion on the columns, arms, and baseplate.

3. Hydraulic System:

   • Inspect hydraulic fluid levels (top up if necessary, using manufacturer-recommended fluid).

   • Look for air bubbles in the hydraulic lines (bleed the system if present).

4. Cables/Chains:

   • Examine cables or chains for fraying, rust, or stretching.

Monthly Checks

1. Comprehensive Safety Test:

   • Perform a load test (with a vehicle at max capacity) to verify the lift holds weight securely.

   • Test overload protection systems (if equipped).

2. Alignment Check:

   • Ensure the lift’s columns are vertically aligned and not leaning.

   • Verify the arm height synchronization (both sides should rise/fall evenly).

3. Electrical Components:

   • Inspect wiring, switches, and control panels for damage or loose connections.

4. Professional Inspection:

   • Schedule a certified technician to inspect critical components (e.g., hydraulic pumps, structural welds).

General Safety Reminders

• Training: Only trained personnel should operate the lift.

• Weight Limits: Never exceed the lift’s rated capacity.

• Documentation: Keep a log of all inspections and maintenance.

By following this routine, you’ll minimize risks of equipment failure, accidents, and downtime.
