FIELD: transport engineering.
SUBSTANCE: invention relates to transport engineering, in particular to suspension trolley carriers. A tractor frame trailer contains a bottom frame with a rear beam. A vertically oriented sheet element with mounting holes for fixing the towbar hitch of the tractor is installed in the rear beam of the lower frame of the trailer. Fastening elements for rigid mutual fixation of the trailer frame in the counter fastening elements designed on the upper part of the tractor frame are installed in the lower part of the lower trailer frame.
EFFECT: invention provides for mobility, acceleration and convenience of towbar hitch coupling and a simultaneous reduction of longitudinal dimensions.
