How Do Frame Machines Work?

An auto body frame machine is used to repair damage to the inner frame of your vehicle from collisions, to restore it to its original shape. This damage occurs in about half of all vehicle accidents, so frame machines are a common piece of equipment in body shops. They do the work that humans simply don’t have the strength for through the use of hydraulics, leverage, and sheer torque.

Frame machine sizes are usually 15 to 24 feet for standard vehicle bodies, and full-size or larger trucks or SUVS may need a frame that runs up to 24 feet. They can come with two or three rotating (360 degree) towers that allow you to apply stress to the vehicle’s frame, and stretch or pull it to straighten it back to its original shape. Frame repair is usually achieved either by pushing or pulling a section of the frame, depending on the damage and the type of frame.
