发明名称 Pull clamps for straightening automobile underframes and door hinge pillars, and their use
摘要 A universal pull clamp includes multiple attachment points and slots. The clamp may be attached to any of a variety of types of damaged automobile frames and locations during their repair. Once the clamp is attached, straightening is accomplished by pulling on the clamp with an external force to return the frame back to its original shape. In one form, the clamp uses a sliding bar and channel arrangement. In another form, the clamp uses a pivoting arrangement.
