Maintaining a tail lift is essential not only for the smooth operation of your vehicle but also for the safety of operators and the longevity of the equipment. Greasing-or lubricating-a tail lift is a fundamental maintenance task that, when performed regularly and correctly, can prevent costly breakdowns, reduce wear and tear, and ensure safe handling of heavy goods. This comprehensive guide will walk you through everything you need to know about greasing a tail lift, from understanding its importance to step-by-step procedures, best practices, troubleshooting, and frequently asked questions.

A tail lift is a mechanical device attached to the rear of a vehicle, typically trucks or vans, designed to assist with the loading and unloading of heavy goods. It operates using a combination of hydraulic, mechanical, and electrical systems to raise and lower the platform.
Greasing a tail lift is crucial for several reasons:
- Reduces Friction and Wear: Regular lubrication minimizes friction between moving parts, preventing premature wear and tear.
- Prevents Corrosion: Grease acts as a protective barrier against moisture and contaminants, reducing the risk of rust and corrosion.
- Ensures Smooth Operation: Proper lubrication guarantees that the tail lift moves smoothly and quietly, reducing operational noise.
- Extends Equipment Life: Consistent greasing can significantly prolong the lifespan of your tail lift, saving on costly repairs and replacements.
- Enhances Safety: Well-lubricated parts are less likely to fail unexpectedly, ensuring safe operation for users and bystanders.
---
- Column Lifts: Feature vertical columns and are often used for heavy-duty applications.
- Cantilever Lifts: Use pivoting arms and are suitable for a wide range of vehicles.
- Slider Lifts: Slide under the vehicle when not in use, ideal for vehicles with limited rear overhang.
- Tuckaway Lifts: Fold away under the chassis, providing clear access to the rear doors.
Regardless of the design, most tail lifts share similar lubrication points:
- Pivot Bearings: Where bolts and bushes meet, creating friction points.
- Hinges: Allow the platform to fold or move.
- Rollers and Sliding Mechanisms: Enable smooth movement along rails or tracks.
- Hydraulic Cylinder Pins: Connect hydraulic rams to the platform or frame.
- Chains (if applicable): Some tail lifts use chains for lifting action.
---
Before starting, gather the following:
- Grease Gun: Manual or pneumatic, compatible with the grease nipples on your tail lift.
- Recommended Grease: Use manufacturer-specified grease, typically a high-quality lithium-based or EP (Extreme Pressure) grease.
- Cloths or Rags: For wiping away excess grease and cleaning parts.
- Personal Protective Equipment (PPE): Gloves, safety glasses, and non-slip footwear.
- Access to the Tail Lift Manual: For specific lubrication points and intervals.
---
- Park Safely: Ensure the vehicle is on level ground, parking brake engaged, and engine off.
- Lower the Platform: Fully lower the tail lift to relieve pressure on the bearing points, making them easier to lubricate.
- Clean the Area: Wipe away dirt, old grease, and debris from all moving parts and grease nipples. This prevents contaminants from entering the bearings.
- Consult the Manual: Refer to the tail lift's manual for the exact locations of grease points. Common areas include pivot bearings, hinges, rollers, and hydraulic cylinder pins.
- Remove Grease Nipple Caps: If present, remove the protective caps to expose the grease nipples.
- Attach Grease Gun: Place the nozzle of the grease gun firmly onto the grease nipple.
- Pump Grease: Squeeze the trigger or operate the pump until fresh grease appears at the bearing edges, forming a visible collar. This indicates the old grease and contaminants are being pushed out.
- Wipe Excess Grease: Use a cloth to remove any surplus grease to prevent the accumulation of dust and grime.
- Hard-to-Reach Points: If certain grease points are inaccessible with the platform fully open, partially close the tail lift to access them. Use the “Open” and “Lower” functions to relieve pressure as needed.
- Chains and Outrails: For liftgates with chains or outrails, use a high-quality, non-detergent, petroleum-based oil instead of grease. Grease can attract debris and cause clogging in these areas.
- Hydraulic Cylinder Pins: Lubricate these points sparingly to avoid contaminating the hydraulic seals.
- Operate the Tail Lift: Cycle the lift through its full range of motion to distribute the grease evenly.
- Inspect for Leaks or Noises: Listen for any unusual sounds and check for hydraulic leaks. Address any issues promptly.
- Replace Grease Nipple Caps: Secure all caps back in place to protect the nipples from dirt.
---
- Standard Use: Lubricate all moving parts at least once a year for single-shift operations.
- Heavy or Multi-Shift Use: Increase frequency to every six months or as recommended by the manufacturer.
- After Cleaning: Always re-lubricate after using high-pressure or steam cleaners, as these can wash away grease.
- Weekly Checks: For high-use environments, consider weekly lubrication of critical points.
- Manufacturer's Recommendation: Always use the grease specified in your tail lift's manual.
- General Rule: Any grease is better than none, but using the correct type ensures optimal protection and performance.
- Avoid Over-Greasing: Too much grease can attract dust and cause build-up, leading to premature wear.
- Maintenance Log: Record each lubrication session, noting the date, points greased, and any observations. This helps track maintenance intervals and identify recurring issues.
---
- Possible Cause: Insufficient lubrication or worn bearings.
- Solution: Grease all pivot points thoroughly. If noise persists, inspect for worn or damaged components.
- Possible Cause: Lack of lubrication, hydraulic issues, or damaged parts.
- Solution: Lubricate all moving parts and check hydraulic fluid levels. Inspect for leaks or damaged hoses.
- Possible Cause: Blocked grease nipple or hardened grease.
- Solution: Remove and clean the nipple, or replace if necessary. Use a solvent to dissolve hardened grease.
- Possible Cause: Over-application of grease.
- Solution: Wipe away excess after greasing and avoid over-lubricating.
- Possible Cause: Worn bolts, bushings, or steel holders.
- Solution: Replace damaged components promptly. Regular lubrication can prevent recurrence.
---
- Always Use PPE: Protect your hands and eyes from grease and debris.
- Secure the Platform: Ensure the tail lift is stable before working underneath or around moving parts.
- Avoid Contaminating Hydraulic Seals: Use grease sparingly near hydraulic cylinders to prevent seal damage.
- Work in a Well-Ventilated Area: Some greases emit fumes; proper ventilation reduces inhalation risks.
- Dispose of Used Materials Properly: Clean up and dispose of oily rags and old grease according to local regulations.
---
While greasing is vital, comprehensive tail lift maintenance also includes:
- Hydraulic System Checks: Inspect fluid levels, hoses, and seals regularly.
- Electrical System Inspections: Ensure all wiring, connectors, and controls are secure and functional.
- Structural Inspections: Look for cracks, rust, or deformation in the frame and platform.
- Operational Testing: Cycle the lift through all motions and test safety features.
