ABSTRACT:
An elongated horizontal base is provided including inner and outer ends and a depending foot assembly is carried by the outer end and supported therefrom for angular displacement relative to the base about an upstanding axis. The foot assembly is adapted for anchoring in a stationary position relative to a floor area above which a vehicle having a body, subframe or frame portion to be straightened may be stationarily positioned and an upright projects upwardly from the base outer end and has a horizontally elongated pull arm pivotally supported therefrom for angular displacement about a horizontal axis extending transversely of the upright, base and pull arm. The axis is centrally spaced between the opposite ends of the pull arm and the latter is mounted for guided longitudinal shifting relative to the axis. The forced structure is operatively connected between the pull arm and the upright for longitudinally shifting the pull arm in a direction displacing the inner end toward the upright and the inner end includes chain section link anchoring means.
