Self-inspection And Handling Guide for Common Faults of Truck Tail Lift

The tail lift of a truck is an important piece of equipment in logistics transportation. Understanding the troubleshooting methods for common faults can effectively ensure work efficiency. BOB-LIFT offers you practical self-check solutions to help you solve problems quickly.

I. Prerequisites for Safe Operation
All operations must be carried out before:

• Cut off the truck's power supply and turn off the main switch on the tail lift

• Operate the manual pressure relief valve to release the pressure of the hydraulic system

• Make sure the tail lift is parked on a flat and solid ground

II. Fault Classification and Handling

1. Abnormal noise fault

• "Creaking" sound of friction:
  Cause: Lack of lubrication at the pin shaft, hinge or chain
  Treatment: Apply lithium-based grease to all lubrication points for maintenance

• The "buzzing" sound of the motor idling:
  Cause: Insufficient hydraulic oil leads to the oil pump being sucked empty
  Handling: Immediately check the oil level in the fuel tank and replenish the anti-wear hydraulic oil to the standard mark

• Abnormal noise accompanied by vibration:
  Cause: Cracks in structural components or loose bolts
  Handling: Immediately stop using it, inspect the main force-bearing points, and contact professional maintenance

2. Oil leakage fault

• Oil leakage from the piston rod of the oil cylinder:
  Reason: The sealing ring has aged and worn out
  Handling: After cleaning, observe and confirm. The sealing ring needs to be replaced (professional maintenance is recommended)

• Oil leakage at the pipe joint:
  Cause: Loose joint or damaged sealing gasket
  Solution: First, try tightening. If it doesn't work, replace the seal

• Fuel tank leakage:
  Cause: Cracks in the box
  Handling: Report for repair immediately and prohibit further use

3. Circuit system failure

• Completely unresponsive:
  Troubleshooting steps:

• Abnormal movement:
  Weak upward movement: Check the oil level and quality (whether it is cloudy and foamy)
  Slow action: Check the viscosity of the oil and the system pressure

• Remote control malfunction:

1. Replace the battery

2. Repeat the code alignment operation

3. Check the connection of the receiver antenna

4. Check the power switch of the truck and the tail lift

5. Check the status of the fuse/circuit breaker

6. Check the battery wiring and the connection of the main harness

III. Hierarchical Maintenance Plan

• Daily: Visual inspection (oil leakage, structural components, fasteners)

• Weekly: Lubrication and maintenance (for all moving joints)

• Monthly: Hydraulic System inspection (oil level, oil quality, sealing performance)

• Annual: Professional comprehensive Maintenance (System pressure testing, structural flaw detection)

IV. Important Reminders

• It is strictly prohibited to carry people on the tail lift

• Do not operate beyond the load limit

• Discontinue use immediately upon discovery of structural damage

• The hydraulic oil should be of the specified type

• For complex malfunctions, please contact professionals

Following this guide can solve most common problems. However, when it comes to the hydraulic core and main structure, please be sure to contact the BOB-LIFT authorized service center for professional maintenance.
