Beauway BW Tail Lift Troubleshooting Guide

Beauway BW tail lifts including cantilever tail lift, folding tail lift, built-in tail lifts, vertical tail lift, concealed tail lift, three-section bumper tail lift and wheelchair lift are designed for heavy-duty applications. This guide provides practical troubleshooting solutions for liftgate not lifting, liftgate not working and hydraulic liftgate problems.

Hydraulic System – Liftgate Not Lifting ▶

Check hydraulic oil (ISO VG32 / VG46)
Ensure oil level is above minimum when lowered
Replace oil if dark or milky
Standard pressure: 16–20 MPa
Inspect hydraulic pump and relief valve
Bleed air if movement is unstable
Check cylinder seals if platform drifts down

Electrical System – Liftgate Not Working ▶

Battery ≥ 12V, recommended ≥12.5V under load
Check wiring, terminals and corrosion
Test control switch and remote
Inspect relay and fuse
Ensure motor receives power

Mechanical System – Platform Issues ▶

Inspect pins and hinges for wear or deformation
Check rollers and guide rails
Ensure platform alignment
Lubricate moving parts every 1–2 months

Power System – Motor Running No Movement ▶

Check pump coupling connection
Inspect motor output and current
Listen for abnormal noise
Replace hydraulic pump if no pressure

Operation and Maintenance ▶

Do not exceed rated load capacity
Inspect system every 1–3 months
Replace hydraulic oil every 6–12 months
Ensure proper operator training

Recommended inspection order: electrical system → hydraulic system → mechanical structure.
