<p>A rectangular base frame which is located on a horizontal surface, carries two parallel beams. The beams are made from rectangular channel profile and their relative spacing on the base frame is variable due to several sets of fixing holes in the frame. The adjustable beams are provided with several sets of anchor points and support arms. The locations of these attachments on the beams is variable over the full length of the beams. Thus, the frame work, which is used to repair damaged chassis and car bodies, can be adjusted to suit any size car.</p> |
