Bench and road tests of platform trucks and semi-trailers of the new PIMR transport system have confirmed the possibility of building a universal version of a ball coupling for semi-trailers with a GVW of 12t. Five new sets of ball couplings and hitches with a ball diameter of 60 mm were built; three couplings were installed in PIMR research semi-trailers, and two sets were made for the needs of homologation tests, which are planned for 2011. Since 2008, PIMR has been conducting work related to the development of a new transport system [1], the basic option of which is a set of road vehicles consisting of a platform truck and a gooseneck semi-trailer. The vehicles are equipped with a new type of ball couplings and hitches with a diameter of 60 mm and a wire-controlled (Brake By Wire) braking system PIMR-EBS (PEBS)[2]. In 2010, the PEBS braking system
installed in the PIMR-P1 trailer (GVW 3400kg) and in the PIMR-N semi-trailer (GVW 4300kg) obtained European type-approval certificates [3,4]. (…)
