FIELD: transport engineering.
SUBSTANCE: proposed boxcar for carrying cars has side walls 1 with ports end face walls 2 with loading doors, two-tier floor 3 and roof with lifting mechanism provided with lifting posts arranged symmetrically relative to longitudinal axis of roof, synchronizing device and drive. Roof lifting mechanism has longitudinal support beams 5 arranged between side walls and roof for resting on walls and displacing with roof. Support beams 5 are resiliently installed on body by means of compensating supports and secured at ends and movably coupled with body by means of guides secured at the same places. Lifting posts are hinge connected by upper end to middle part of support beams and are connected from below by transformation mechanisms with synchronizing device made in form of cross drive shaft secured on body.
EFFECT: simplified design, improved reliability.
