Accidents at service stations are more common than you’d think, but when a Volvo RB is involved in a multi-vehicle shunt with a trailer hitched, the physics involved are massive. We recently took on a project that tested every bit of our structural expertise.
The impact wasn’t just a “fender bender.” Because the trailer was hitched, the energy of the shunt didn’t just crumple the panels—it traveled through the entire skeleton of the vehicle.
The Damage Assessment
When the unit arrived at the shop, the visual damage was only the tip of the iceberg. Our initial inspection revealed:
Twisted Chassis Frame: The most critical issue. The lateral force from the shunt had “diamonded” the frame, meaning it was no longer a perfect rectangle.
Buckled O/S/F Door Aperture: The off-side front door frame was compressed. If the aperture is out by even a few millimeters, the door won’t seal, causing wind noise and structural weakness.
Bulkhead Compromise: The bulkhead (the wall between the engine and the cab) had shifted, requiring intricate metalwork to restore its integrity.
The Repair Process
1. Frame Realignment
We began with the backbone of the truck. Using our heavy-duty hydraulic pulling equipment, we anchored the Volvo to the floor and applied controlled pressure to “untwist” the chassis. This is a game of precision; we don’t stop until the measurements align perfectly with Volvo’s factory specifications.
2. Structural Metalwork & Bulkhead
Once the frame was straight, we tackled the bulkhead repair. This involved stripping back the interior to access the structural points. We also reworked the o/s/f door aperture, pulling the pillars back into their original geometry so the door now closes with that satisfying “factory” click.
3. Full Wheel Alignment
A straight frame doesn’t always mean straight wheels. After a shunt of this magnitude, every axle needs to be recalibrated. We performed a full 3D wheel alignment to ensure:
Maximum fuel efficiency.
Even tire wear (saving the client thousands in the long run).
Correct handling and driver safety.
The Result
The Volvo RB is now back on the road, looking and—more importantly—performing as if the accident never happened. In the world of heavy haulage, “good enough” isn’t an option. Whether it’s a minor dent or a major chassis twist, we restore the structural integrity your fleet depends on.
Expert Tip: If your truck has been in a shunt, even if it looks okay, have the chassis checked. A slight twist can cause “dog-tracking,” which ruins tires and compromises safety at high speeds.
Is your fleet due for a safety inspection or structural repair?
