In a device for straightening vehicle bodies, a long-stroke traction jack is mounted vertically within a vertical column, the jack body being attached to the lower end of the column. The column is carried by a movable base and can be attached to the ground by means of retaining chains. One end of a traction chain passed over a guide pulley and engaged within the interior of the column is attached to the free end of the jack operating rod.

A device for straightening vehicle bodies comprising a vertical column having a guide pulley supported at an upper end thereof and being carried upon a movable base, a traction jack vertically disposed within said vertical column and having a body portion and an operating rod extending from said body portion, a traction chain for connection to the vehicle to be straightened when applying a straightening force to the vehicle body, said traction chain having one end coupled within the interior of said vertical column to the operating rod of said traction jack and another end passing out from the interior of said vertical column over said guide pulley supported at the upper end thereof for connection to the vehicle body upon which a straightening force is to be applied, a collar carried on said vertical column and selectively positionable in a vertical direction relative thereto, said collar including a guide pulley positioned to engage said traction chain for applying a straightening force to the vehicle body in a predetermined direction at a vertical height determined by the selective positioning of said collar, a first retaining means engageable with said collar for attaching said device to the ground to secure said device in a fixed position while applying a straightening force to a vehicle body, said movable base including a guide pulley supported thereby with a second retaining means passing thereabout, said second retaining means being secured at one end to said collar and at an opposite end to said body portion of said traction jack, said device being movable about the vehicle body to be straightened, free from any connection therewith other than said traction chain for applying a straightening force thereto, said movable base upon which said vertical column is carried having a horizontal bottom wall which is disposed a short distance above the ground, and runner wheels carried by said movable base and having resilient pads positioned between said movable base and said runner wheels so that upon application of a straightening force to the vehicle through said traction chain, said horizontal bottom wall will compress said resilient pads and contact the ground to enhance the stability of the device during use.
