A transport vehicle, e.g. a yoke-frame wagon(1), has a rearwardly-open U-shaped frame(2) formed of two side members(3) & a front cross member(4). Each side member has a rear swingable frame member(10) with a wheel(9) and the cross member has a swingable fore frame member(5) for connecting the frame to a traction & steering device. The fore & rear frame members are swingable by power actuators(17,27) for raising & lowering the frame. The rear frame members are provided with grippers for engaging a load adjacent these members in order to tip the load by swinging of the members.
