Abstract: A vehicle-straightening bench (20) is utilized to apply pulling forces to a damaged vehicle chassis to restore the damaged chassis to an original configuration. The bench includes a vehicle platform (22) with a carriage track (24) having a plurality of carriage assemblies (100) movably received by the carriage track (24). Each carriage assembly (100) supports a pulling assembly (200) for applying the pulling forces. A trapezoidal carriage body (102) of the carriage assembly (100) rolls in the carriage track (24), and the carriage assembly also includes a tower positioning mechanism (104) to hold the pulling assemblies (200) in place while the carriage body (102) is are rolled on the track (24). The carriage assembly (100) also includes a locking mechanism (106) to lock them in place during a vehicle a pull.

Abstract: An improved measuring system for use in combination with vehicle repair equipment includes a pair of transverse bars mounted at a fixed position in space relative to the vehicle with a longitudinally extending and laterally movable bar assembly attached by sliding brackets to the transverse bars. Additional longitudinal bars are attached to the opposite ends of the transverse bars. Supplemental measuring equipment is attachable to all of the bars in order to effect point to point measurements on a vehicle in order that the point to point measurements may be compared with known standards.

Abstract: An improved measuring bar device includes first and second parallel bars retained in a center housing by an array of biased and canted rollers that engage cam surfaces defined by the bars to provide for equal and opposite movement of the bars while maintaining the bars in parallel array.
