The user-friendly, semi-pneumatic lifting fifth-wheel coupling is installed in twin-axle Ultra semitrailer tractors as an option. The two coupling heights enable both large and standard semitrailers to be combined with Ultra semitrailer tractors without problem, despite their low frame height. This is made possible thanks to the scissor-type design of the coupling substructure, in conjunction with a pneumatic lifting element. In both positions of the coupling, a mechanical lock ensures 100 % operational reliability. It doesn't matter whether the driver needs to pick up a large semitrailer with a parking height of 1000 mm or a standard semitrailer with a parking height of 1200 mm from the yard -- the robust, height-adjustable fifth-wheel coupling allows complete flexibility.
