The disclosure relates to a semi-trailer (1) for transporting containers which is connected to a tractor unit, comprising a gooseneck chassis and a container lifting device with at least one crane part (3) displaceable along the chassis (2). The chassis comprises frame portions which are vertically displaced relative to each other, where the available vertical space for driving the displaceable crane part (3) is limited particularly in the transition between said frame portions. The displacement of the crane part (3) on one frame portion of the chassis (2) takes place by means of a linearly operating, longitudinally variable elongate actuator, which both in the retracted and in the extended state is positioned substantially within the height limits of the chassis and has a substantially constant angle to the chassis (2). A vertically articulated link arm is at one end connected to a driving part of the actuator and at the other end articulated to said displaceable crane part (3).
