Abstract: The disclosure relates to a device in load-carrying vehicles with a so-called bogie lift, including a sprung (1) drive shaft which carries driving wheels and a running axle (2) on which running wheels are suspended. The running axle (2) is arranged, by means of a first lever (3) operating between the running axle (2) and one end of the spring assembly (1) of each respective driving wheel and rotatably disposed by means of an operating device (8) in relation to the frame (4) of the vehicle, to be raised and lowered, by means of a second lever (5) in relation to the frame (4) of the vehicle in order thereby to move the running wheels of the running axle (2) away from and into contact with that surface on which the vehicle rolls, in response to the axle pressure which is intended to be exerted on the surface. The movable, free end of the second lever (5) is arranged to actuate the first lever (3) a distance from the fulcrum of the second lever (5). At its movable end, the second lever (5) is designed with a plurality of surfaces (5a-5j; 6, 7) which are located at different distances from the fulcrum (10) of the second lever (5). The surfaces (5a-5j; 6, 7) are arranged to be turned, by the operating device (8), about the fulcrum (10) for load-transferring contact with different parts of the first lever (3).
