What are the special features of semi-trailer trucks with short coupling systems?

You answered everything correctly. Semi-trailer trucks with short coupling systems have several specific characteristics. First, their cornering behavior differs from conventional articulated trucks, mostly because the distance between the tractor and trailer is shorter, affecting how the vehicle moves through curves. Second, the coupling device experiences more wear since the movements and forces on the connection point are higher due to the reduced space and sharper angles during maneuvers. Third, the shorter coupling system allows for a larger usable loading area compared to conventional couplings, optimizing space for cargo. Knowing these features helps you understand the handling, maintenance, and loading advantages and challenges of these truck configurations in practice.
