Maintenance of Wheel Forks and Load Wheels in Stackers

A stacker concentrates tons of lifting and traveling pressure onto just a few square centimeters of space: the load wheels. The wheels located under the forks and the wheel forks (linkage mechanisms) that connect them to the chassis are the first line of defense directly battling the floor irregularities of your warehouse. At Izmir Demir Lift, we share professional maintenance tips to extend the life of these critical components.

 

1. Deformation Control in Wheel Forks

Dropping heavy loads harshly onto the floor or driving the machine quickly over thresholds can cause the steel forks holding the wheels to bend.

The Risk: Even a millimetric bend in the fork ruins the wheel alignment. This leads to uneven wheel wear and causes the machine to pull to one side instead of traveling in a straight line.

The Solution: During periodic maintenance, lift the forks and visually inspect the fork connection pins and bearing seats.

 

2. Single vs. Double (Tandem) Load Wheels

The tandem (double) wheel structure we offer in our machines doubles the contact area of the load with the floor.

The Advantage: Tandem wheels absorb the impact especially when passing over floor grates, rails, or small thresholds in your warehouse. By distributing the load on the fork evenly, it reduces mechanical wear by 40%.

 

3. Bearing Protection Covers and Cleaning

The bearings at the center of the load wheels are highly sensitive to dust, strings, and stretch film residues on the floor.

Maintenance: Check daily if the wheels rotate freely. If there is any sticking, open the bearing cover, clean the accumulated foreign objects, and lubricate with high-pressure lithium grease.

 

Industrial Trend of the Day: In 2026 logistics trends, the "Floor-Friendly Equipment" concept stands out. The increasing cost of epoxy coatings on facility floors pushes businesses to pay more attention to wheel and fork maintenance. The 2-year service warranty provided by Izmir Demir Lift keeps the fork and wheel bearing groups under protection, securing both your floor and your budget.
