ABSTRACT:
An inside loader, embodied as a semi-trailer for a tractor truck for over-the-road transport of transport frames for transporting flat sheets in a carrying frame having parallel longitudinal members, on the outside of which axle rockers, supported on air suspension bellows, are articulated to support a plurality of rear wheels. On the inside of each of which a profiled supporting section is secured, wherein, in order to load a transport frame, the semi-trailer is backed up, with its air springs deflated and with its longitudinal members enclosing the transport frame, in such a way that the profiled supporting sections of the longitudinal members of the frame coincide vertically with longitudinal members of the transport frame, which, at the end of the reverse movement, is raised into the transport position through inflation of the air spring bellows. The trailer coupling is disposed on a rocker supported by an air spring and the axle rocker of the rear wheels has a stop for emergency operation of the trailer in case of deflated air springs. The stop can be disengaged for the purpose of loading and unloading, wherein the section heights of the support sections and the longitudinal frame sections of the transport frame overlap in such a way that the semi-trailer, with the stops disengaged and axle and coupling rocker springs deflated, can be moved with sufficient ground clearance. The transport sections vertically overlap the sections of the longitudinal frame members of the transport frame, which rests with its frame directly on the base while still providing clearance.
