Why Does a Hand Pallet Truck Become Uneven Over Time?

1. Introduction

Hand pallet trucks are widely used in warehouses and factories for lifting and moving goods. However, after long-term use, many users encounter the issue of a pallet truck being higher on one side than the other. What causes this, and how can it be fixed?

2. Causes of Uneven Hand Pallet Trucks

🔹 2.1. Unevenly Worn Wheels

PU/Nylon wheels wear unevenly due to frequent turning in one direction or rolling over rough surfaces.
Uneven wheel wear causes forks to tilt, making the truck unbalanced.

🔹 2.2. Hydraulic System Issues

Hydraulic oil is low or contaminated.
Seals or valves inside the pump wear out, making the two lifting cylinders unbalanced.

🔹 2.3. Bent Forks or Cylinders

Frequently overloaded beyond rated capacity.
Strong collisions with pallets, walls, or goods.

🔹 2.4. Hydraulic Cylinder Oil Leakage

One side leaks oil, losing pressure faster, causing the forks to drop unevenly.

3. Solutions to Fix the Problem

Inspect and replace wheels: Replace both wheels instead of just one.
Refill or change hydraulic oil: Use the recommended oil.
Repair hydraulic pump: Replace seals or valves if worn.
Straighten or replace forks: If bent or severely damaged.
Regular maintenance: Clean and lubricate wheels, axles, and pump.

4. Conclusion

The issue of a hand pallet truck being uneven mainly comes from uneven wheel wear and hydraulic system failure. To prevent this, businesses should maintain equipment regularly and avoid overloading.
