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.

In an inside loader for the over-the-road transport of transport frames, especially for the transport of flat glass in a chassis with parallel longitudinal frame members, in the form of a semi-trailer with a tractor, wherein are articulated axle rockers, supported on their outsides by air suspension bellows, for the support of a plurality of rear wheels, on the inside of which profiled support sections are secured, and wherein the semi-trailer, in order to load a transport frame, is backed up, with air springs deflated and with the longitudinal frame members enclosing the transport frame, in such a way that the support sections of the longitudinal frame members vertically overlap the longitudinal frame members of the transport frame which, after the backing-up is completed, is raised into the transport position by means of inflation of the air spring bellows, the improvement comprising: a rocker (15) secured to the trailer, a trailer coupling (16) carried by said rocker, an air spring (22) supporting said trailer coupling on said rocker, axle rockers (23) pivotally associated with the rear wheels (5,6,7), air springs (29) associated with each said axle rocker for maintaining said rockers in transport condition, stop means (34) carried by the trailer for normally limiting movement of said axle rockers in one direction upon deflation of said air springs to permit emergency operation of the trailer, said stop means being disengagable to permit unlimited movement of said axle rockers in said one direction for loading and unloading upon deflation of said air springs, the section heights of the transport sections (51,52) and the longitudinal frame members (38,39) of the transport frame (37) being such that the semi-trailer (1) can be moved with sufficient ground clearance when said stop means are engaged and the air springs (22,24) are deflated, and the transport sections (51,52) vertically overlap the portions of the longitudinal frame members (38,39) of the transport frame (37) which directly rest on the base (36) of the trailer while providing free play.
