Trailer Repair & Maintenance
Trailer Maintenance for the Half of Your Fleet Nobody Watches
Structural PMs and Repairs for Dry Vans, Reefers and Flatbeds
Tractors get attention because they throw codes. Trailers sit in drop yards and warehouse pools until a door won’t seal or a light fails at the scale. We service your trailers where they’re parked, on the same schedule as your tractors.
What We Do
Trailer Repair and Preventive Maintenance
Dry Van Structural PMs
Doors, floors, crossmembers, lighting and running gear inspected and serviced on a set schedule.
Reefer Trailer Structural PMs
Door seals, floors and box integrity checked so the trailer holds temperature and stays road-ready.
Brakes, Air Suspension & ABS
Brake adjustment, air bag assessment, ABS sensor and relay valve diagnostics, and shoe and drum audits.
Flatbed Trailer PMs
Deck structure, lighting, wiring and brakes inspected and repaired.
Landing Gear Maintenance
Landing gear inspected, lubricated and repaired so trailers drop and hook without a fight.
Door Roll & Seal Integrity
Roll-up and swing doors checked for smooth operation and a tight seal.
Floor & Crossmember Audits
Floors and crossmembers checked for soft spots, cracks and damage before a forklift finds them.
Lighting & Wiring Trace
Trailer lighting and wiring faults traced to the source, not just a new bulb.
The Trailer Problem
A Trailer That Fails Costs the Same Load as a Tractor That Fails
Trailers don’t throw fault codes. The only way to catch a problem is to inspect the trailer on a schedule, and that’s where trailer preventive maintenance pays for itself.
Damaged Freight
A failed door seal or soft floor can ruin a load before anyone notices.Out-of-Service Defects
Brake, lighting and tire defects on trailers put the whole rig out of service at inspection.Stuck at the Drop Yard
A trailer with a bad landing gear or air leak can’t be hooked, and the load waits.
