The device (10) has a frame (16) receiving a load (12) with a front wheel pair (18) and a rear wheel pair (20) provided in a driving direction. The front wheel pair is firmly connected with the frame. The rear wheel pair is movably arranged in direction of the frame such that the frame or a section of the frame is brought into contact with a wheel of the rear wheel pair or parts of the rear wheel pair for releasing a braking action, when the frame is lowered in a direction of an axle (54) of the rear wheel pair.
