Abstract: Apparatus for straightening automotive bodies and frames. The device includes a base and a hollow column within which an hydraulic cylinder is positioned. A top cap is applied to the column and includes a rotatable guide pulley about which a main tension chain passes for connection with an end of the hydraulic cylinder. A movable pulley housing is slidably carried along the column and includes a second guide pulley and a chain guide to guide a chain in a substantially horizontal direction outwardly from the movable pulley housing. A pair of outwardly extending arms are carried on another movable housing and include floating links on each lateral bar to permit the separate application of pulling forces independent of the main tension chain and along a line that does not pass through the column axis. The lateral arms can also be provided on the movable pulley housing.
