Straightening of Wrecked Car Frames
Most of the auto collisions that take place on roads involve some damage on the vehicle's frame. However, modern vehicles have been designed with crumple zones that are able to absorb all types of impacts during accidents to save the passengers inside. Even though vehicles have been made safer, their frames remain susceptible to all types of damages both in low and high speed. Some damages may lead to writing the vehicle off the road while others may be straightened and restored back in place.
How Wrecked Frames are repaired
Automotive body shops have well specialised machines that use powerful torques and hydraulic mechanisms to straighten wrecked frames back to their normal state. The forces induce the machine to either pull or push the frame back to its normal shape based on the degree of damage.
For instance, the automotive frame machine is the most commonly used in garages to straighten wrecked car frames after an accident. The machine works as a huge platform together with the help of a hydraulic ram, two towers, and run chains. The system clamps to the vehicle's body to make gradual multi-directional pulls. It is necessary to ensure that the vehicle is well clamped downwards using clamps and brackets that are mounted on the pinch just before the process begins. This prevents the auto body from moving when straightening its frame.
The operational principle of the machines is reversing the moment of inertia that hit the body from collision. Once the frame is restored back to its required position, new panels can be set in place.
Other Processes Involved in Frame Straightening
To ensure that all the parts are properly shaped and aligned to their original factory specifications, the auto body shop employs the use of laser measurement systems. Ultrasound may be used at the beginning to diagnose the specific degree of damage on the frame and come up with the exact prescription to address the damage.
If all the techniques of frame straightening fail, technicians may opt to cut and remove the bend portions of the frame and replace by welding in new straight pieces. If this is the only choice left, one has to be careful since the process of welding could reduce the structural integrity of the frame at specific weld points. You should be sure of the level of professionalism and experience of the technician handling the project when it gets to this point.
