How Does an Auto Body Frame Machine Work?
A damaged vehicle is driven up onto the platform and bolted to rigid clamps that hold it firmly in place so it can’t move forward, backward or sideways. Chains on the towers are attached to specific points on the car’s frame, based on where the diagnostics indicate straightening is required. The tower’s hydraulic equipment gradually increases the tension on the chains to pull that section of the frame back into shape. The machine’s electronic measurement system verifies that the adjustments are made correctly, so the frame is restored to the manufacturer’s exact specifications and the vehicle drives correctly.
