Construction & Equipment Trailer Repair
Mondak Equipment repairs and inspects heavy construction and equipment trailers, from routine wear items to structural, hydraulic and electrical problems.
The Trailer Is Part of the Equipment
A loader, excavator or skid steer does not do much good if the trailer underneath it cannot safely get it to the next job.
We work on the trailer as a complete piece of equipment, rather than the part that happens to be broken today.
Equipment Trailer Repair
We work on:
- Equipment and machinery trailers
- Tilt trailers
- Hydraulic tilt trailers

DOT Trailer Inspections
Mondak performs DOT periodic inspections on commercial and equipment trailers.
We inspect the systems and components that affect safe operation, including:
- Brake systems
- Suspension
- Axles and wheel ends
- Tires and wheels
- Lighting and electrical
- Coupling devices
- Frames and structural components
- Other applicable safety components
If we find a problem during the inspection, we can handle many of the repairs in-house.
Inspection, repair and documentation in one place helps keep the trailer ready for the road and the equipment moving.
Brakes, Suspension & Running Gear
Trailer problems often show up first as tire wear, heat, pulling, noise or a wheel end that simply does not feel right.
We repair and troubleshoot:
- Electric and air brake systems
- Brake assemblies and drums
- Hubs and bearings
- Axles
- Suspension components
- Springs and equalizers
- Air suspension
- Wheel-end problems
- ABS and trailer wiring
- Lighting and electrical systems
If a spindle or axle end is damaged, Mondak also provides dedicated Trailer Spindle Repair & Replacement services.
Hydraulic Trailer Systems
Hydraulic tilt decks, ramps and other powered functions depend on more than a cylinder.
We work on:
- Hydraulic cylinders
- Pumps and power units
- Valves
- Hoses and fittings
- Electrical controls
- Batteries and charging circuits
- Switches and wiring
- Leaks, slow operation and intermittent problems
If the trailer will lift empty but struggles with a machine on it, we want to know why before turning up the pressure.
Frames, Ramps & Structural Repair
Heavy trailers take abuse.
Loading equipment, rough roads and years of service can wear out ramps, hinges, decks, mounts and structural components.
Mondak can handle:
- Ramp and hinge repair
- Deck repairs
- Cracked or damaged brackets
- Jack and landing gear repairs
- Coupler and hitch repairs
- Fender and mounting repairs
- Structural welding
- Fabrication and reinforcement
- Worn pins and pivot points
The goal is to repair the problem without creating another weak point somewhere else.
When the Part Isn't on the Shelf
Older and specialized trailers do not always have an easy parts answer.
When the original component is damaged, obsolete or difficult to source, we can look at other options, including repair, machining, fabrication or adapting a replacement component where appropriate.
Sometimes replacing the entire assembly makes sense.
Sometimes it doesn't.
Keep the Trailer Ready to Work
Whether you need a DOT inspection or you are dealing with a wheel-end problem, hydraulic failure, damaged ramp or cracked structure, bring us the trailer, or tell us what it is doing.
Give us the trailer manufacturer, type and problem. We'll start there.
