Liftgate Basics

Understanding liftgate types and how they work helps with proper maintenance.

Types of Liftgates

Different liftgates serve different needs.

Tuck-away liftgates – Fold under the vehicle when not in use. Save space and improve maneuverability.
Railgates – Heavy-duty platforms that move up and down a vertical track.
Cantilever liftgates – Adjustable platforms that tilt for easier loading and unloading.

Electrical vs. Hydraulic Systems

Liftgates operate using an electric motor or a hydraulic pump. Users control the liftgate with a panel located inside or near the lift. Knowing the differences helps diagnose common issues.

Why Liftgates Are Important

Many industries depend on liftgates for daily operations:

Retail & Logistics – Moving shipments quickly.
Emergency Services – Transporting heavy medical equipment.
Construction & Manufacturing – Handling large materials efficiently.

Why Liftgate Servicing Matters

Liftgates experience wear and tear over time. Regular maintenance ensures smooth operation, prevents expensive repairs, and keeps businesses compliant with regulations.

Safety

A damaged liftgate can cause accidents. Regular inspections prevent malfunctions that put workers at risk.

Preventing Costly Repairs

Ignoring small issues leads to bigger problems. Fixing minor issues early prevents expensive breakdowns.

Regulatory Compliance

Many industries must follow maintenance regulations. Keeping liftgates in good condition ensures compliance and extends their lifespan.

Signs You Need Liftgate Maintenance

Liftgates show warning signs before they fail. Recognizing these signs helps prevent major issues.

Hydraulic Fluid Leaks

Signs: Oil puddles under the liftgate, oily residues on parts.
Fix: Check seals and hoses, replace worn-out components.

Unusual Noises

Signs: Grinding, whining, or banging sounds during operation.
Fix: Tighten or replace bearings, gears, or hydraulic parts.

Slow Lifting or Lowering Speeds

Signs: The liftgate moves slower than normal.
Fix: Check hydraulic fluid levels, remove air from the system, and inspect electrical connections.

Intermittent Operation

Signs: The liftgate sometimes works and sometimes doesn’t.
Fix: Secure loose electrical connections, repair damaged wiring, or replace faulty switches.

Difficulty Securing the Liftgate

Signs: The liftgate does not stay locked in place.
Fix: Inspect and replace worn locking mechanisms or faulty hydraulic components.

Battery Problems (For Electric Liftgates)

Signs: The liftgate struggles to operate due to weak power.
Fix: Test and replace the battery if needed.

Platform Misalignment

Signs: The platform is uneven or does not sit correctly.
Fix: Clean debris, lubricate pivot points, and adjust alignment.

Rust and Corrosion

Signs: Rust forms on hinges, platforms, or metal components.
Fix: Apply rust inhibitors and protective coatings to prevent further damage.

Basic Liftgate Maintenance

Routine maintenance keeps liftgates working properly and extends their lifespan.

Fluid Checks and Changes

Check hydraulic fluid levels regularly.
Replace hydraulic fluid as recommended by the manufacturer.

Component Lubrication & Cleaning

Apply lubricant to hinges, rollers, and lift chains.
Remove dirt and debris before applying lubricant.

Electrical System Inspection

Check wiring, connectors, and control panels for damage.
Test switches, sensors, and emergency stop functions.

Safety System Testing

Verify that warning lights and alarms work properly.
Perform emergency stop tests to ensure quick response.

Advanced Liftgate Maintenance

Fleet managers and operators should take extra steps to prevent failures.

Systematic Troubleshooting

Liftgates experience electrical, hydraulic, and mechanical wear. Identifying issues early prevents sudden failures that disrupt operations. Regular inspections should include checking wiring, monitoring hydraulic pressure, and assessing moving parts for wear.

Manufacturer diagnostic tools help pinpoint faults accurately, allowing for quick, targeted repairs. Addressing issues promptly keeps liftgates running smoothly and minimizes downtime.

Predictive Maintenance

Predictive maintenance uses sensors to track cycle counts, hydraulic pressure, and battery health in real time. Analyzing usage data helps fleet managers anticipate failures and schedule service before problems arise.

This proactive approach prevents unexpected breakdowns, reduces repair costs, and ensures liftgates remain reliable for daily operations.

When to Call a Professional

Some repairs require expert knowledge and specialized tools.

Hydraulic System Failures: Major leaks, pump malfunctions, or cylinder failures require professional repair.
Electrical System Repairs: Complex wiring faults, switch malfunctions, and control module issues need expert attention.
Structural Repairs and Welding: Fixing rusted platforms, cracked frames, or bent components requires certified welding.

Establishing a Liftgate Maintenance Schedule

A structured maintenance plan helps prevent breakdowns and reduces repair costs.

Routine Inspections: Perform weekly or bi-weekly visual inspections for wear, damage, or leaks.
Scheduled Service Intervals: Follow manufacturer guidelines for fluid changes, lubrication, and inspections.
Record-Keeping: Maintain records of maintenance dates, performed tasks, and detected issues.
