THE PROCESS OF THE INSTALLATION A TWO POST HOIST

Installation Guidelines for Vehicle Lifts

I. Pre-Installation Foundation Requirements

To prevent equipment tilting, abnormal noise, or collapse due to weak foundations, ensure the following before installation:

1. Newly poured concrete must cure for at least 20 days.

2. Requirements vary by lift capacity:

   • ≤4.5-ton two-post lifts:

     • Concrete strength: C25

     • Thickness: ≥200mm

   • 5–6-ton two-post lifts:

     • Concrete strength: C30

     • Thickness: ≥250mm

   • 8-ton two-post lifts:

     • Concrete strength: C30–C35

     • Thickness: ≥400mm

3. Horizontal error between two posts: <5mm.

4. Ensure lift baseplates directly contact the concrete foundation for stability.

II. Workspace Dimensions

1. Recommended bay size: (7000–8000) x 4000mm (4S standard).

2. Ensure sufficient space for vehicles to drive onto/off the lift.

3. Prevent vehicles from hitting ceilings. For low ceilings, install ceiling proximity alarms.

III. Power & Air Supply Setup

1. Electrical requirements:

   • Three-phase wire: ≥2.5mm²

   • Single-phase wire: ≥4mm²

   • Power outlets must be installed 1.5m above ground near the main post.

   • For temporary power during installation: Provide 415V three-phase power.

2. Ceiling height:

   • 4m for overhead lifts.

   • 3.5m for baseplate lifts.

IV. Tools & Materials Preparation

1. Per two-post lift:

   • 13L of L-HM46 anti-wear hydraulic oil.

   • 2T+ forklift for unloading and moving equipment.

2. Follow the manufacturer’s detailed installation tool list.

V. Erecting Posts & Aligning Dimensions

1. For overhead lifts: Pre-assemble crossbeams on the ground.

2. Route hoses, wires, and cables through crossbeams to both posts.

3. For baseplate lifts: Erect posts directly and confirm dimensions.

4. Maintain ≥3m clearance between walls and lift baseplates.

5. Adjust post spacing per lift model specifications.

VI. Securing Expansion Bolts & Adjusting Post Verticality

1. Use drill bits matching bolt sizes.

2. Drill holes 3cm deeper than bolt length.

3. Clean debris, insert bolts, and secure.

4. Use a plumb bob to ensure posts are vertical, then tighten bolts.

VII. Installing Pump Station, Wiring, & Lift Arms

1. Mount the pump station on the post.

2. Fix the control box to the post.

3. Connect limit switches, motor cables, and wiring to the control box.

4. Fill the pump reservoir with No. 46 anti-wear hydraulic oil.

5. Install lift arms with shorter arms toward the vehicle front.

VIII. Power Connection & Lift Testing

1. Connect the control box to external power.

2. Raise the lift 400mm (vent inverted cylinders by loosening air-release valves; upright cylinders require no venting).

3. Lower the lift fully and tighten cables.

4. Verify synchronous operation of safety locks on both posts.

5. Test with a vehicle: Raise to maximum height, engage locks, and ensure 3cm clearance at the upper limit.

IX. Commissioning & Operation

1. Apply grease to lift cables and slide rails.

2. Tighten all hose fittings and bolts.

3. Train operators on safety protocols before use.
