A structure for buckling the frames of a two-sectioned, centrally articulated truck chassis has a pair of links swingably mounted on the front frame and pivotally connected to a piston and cylinder power assembly carried by the rear frame. Additionally, a control member in overlying, vertical alignment with the piston and cylinder assembly swingably connects the links to the rear frame. As the piston is actuated, the force directly bears on the links, causing the latter to swing and simultaneously move the control member, causing the frames to move upwardly and spread while tilting about their articulation. The entire force presented by the rear mounted cylinder and piston assembly bears directly on the opposite, front frame such that a minimum amount of power is required to effect the tilting. Also, the vertical alignment of the piston and cylinder with the control member reduces bending and bowing stresses in the structure.
