PCT No. PCT/FI92/00106 Sec. 371 Date Oct. 8, 1993 Sec. 102(e) Date Oct. 8, 1993 PCT Filed Apr. 7, 1992 PCT Pub. No. WO92/18263 PCT Pub. Date Oct. 29, 1992The invention concerns a straightening beam for an automotive bodyshell straightening jig, said straightening beam comprising a vertical beam (1), which is sideways rotatable attached to a beam base (11), which is detachably mountable to the frame of the automotive bodyshell straightening jig, and the beam further incorporating guidance means (2) for guiding a pulling tool member (3) attachable to the automotive bodyshell and for adjusting the position of the pulling tool member. With prior-art apparatuses it is not always possible to bring the pulling tool member sufficiently close to the point to be pulled or to exert the full power of the actuator via the pulling tool member. The straightening beam according to the invention incorporates an extension beam (4) attached to a vertical beam (1) so as to be rotatable and lockable at various angles. Furthermore, the vertical beam (1) incorporates a power actuator which exerts its force downward along the vertical beam and to which the pulling tool member is attached.
