At Lone Star Truck & Trailer Services, we understand that walking floor trailers work hard — and when something breaks, your entire operation comes to a stop. Whether you’re hauling wood chips, mulch, scrap metal, agricultural products, or bulk commodities, your walking floor system needs to run smoothly and reliably every single load.

That’s why our technicians specialize in complete walking floor trailer repair and maintenance, from the hydraulics and drive units to the flooring and frame.

Floor System Repairs

The walking floor system is the heart of these trailers — and it takes a beating every day. We repair and replace:

• Damaged aluminum slats or planks caused by heavy or uneven loads

• Worn or broken bearings and seals that cause binding or leaks

• Bent or cracked cross drives

• Broken push blocks and slat connectors

• Worn-out seals or bushings along the floor track

• Misaligned or uneven floor sections causing jerky or noisy movement

We can also re-deck entire walking floors, restoring smooth operation and eliminating product hang-ups.

Hydraulic System Repairs

Your floor is powered by hydraulic precision — and leaks or weak pressure mean downtime. Lone Star expertly repairs:

• Hydraulic cylinders (rebuilds, seal replacement, or full replacement)

• Control valves and flow regulators for smooth floor operation

• Pump failures or line leaks

• Reservoir cleaning and fluid flushing

• Pressure testing to ensure even performance across all strokes

We use only high-quality hydraulic components and fittings to guarantee reliability under heavy load.

Drive Unit & Chain Assembly Repairs

When the drive unit or chain assembly wears out, your floor won’t advance properly. We inspect and repair:

• Drive hubs, gears, and shafts for wear or cracks

• Drive chains that have stretched or seized

• Bearings, seals, and sprockets

• Floor drive motors and mounts

• Mounting brackets and alignment tracks

We ensure every moving part in your drive system is synchronized and properly tensioned.

Electrical & Control Systems

Modern walking floors rely on more than just hydraulics — electrical systems keep everything in sync. We repair:

• Wiring harnesses and switches controlling the hydraulic system

• Remote control systems and sensors

• Indicator lights and circuit protection

• Fuse boxes and relay systems

From diagnostics to full rewiring, Lone Star keeps your system responsive and dependable.

Structural & Frame Repairs

Heavy use, uneven loading, and road stress can bend or crack your trailer’s frame and body. We handle:

• Cracked welds and cross-member repairs

• Corrosion on support beams or frame rails

• Damaged rear headers and door frames

• Front wall and bulkhead separation

• Landing gear replacement or reinforcement

We bring frames back to factory alignment and ensure the trailer tracks straight under load.

Door & Seal Repairs

Your product needs to stay in — and the weather needs to stay out. We repair:

• Rear barn doors and seals that no longer close tightly

• Roll-up door tracks, rollers, and hinges

• Leaking or torn weather seals

• Door frame alignment issues

Lone Star ensures your trailer stays sealed, secure, and DOT-compliant.

Suspension, Axle & Brake Repairs

Because walking floor trailers are heavy-duty haulers, their undercarriage components see extreme wear. We service:

• Airbag and suspension leveling systems

• Leaf springs and torque arms

• Wheel bearings, hubs, and seals

• Brake shoes, drums, rotors, and lines

• ABS sensors and wiring

Our goal is to keep your trailer rolling safely and reliably — load after load.
