ABSTRACT:
A pull tower for pulling upon a chain and correcting damaged portions of a vehicle includes a combination chain height adjustment and pulley mechanism which is positioned on the tower and with a collar having opposite side plates facing opposite side surfaces of the tower. A front end of the mechanism includes a pulley over which a chain is trained and a front crossbar extending between the side plates and adjacent the tower front surface. The mechanism has a rear end including a rear crossbar spaced from the front crossbar to loosely straddle the tower and a U-shaped spring which extends between the rear crossbar and lugs which extend from the tower rear surface to urge the rear crossbar away from the tower. The mechanism provides an angled, wedging fit of the chain height adjustment and a pulley mechanism on the tower at selected higher locations. Preferably, the tower is mounted to a carriage movably positionable about a work rack, although it can be floor mounted if desired.
