FIELD: transport.

SUBSTANCE: invention relates to transport. The vehicle for loading, transporting and unloading rolls of hay contains a chassis, a platform and a trailer pivotally connected to it by means of a turntable, a tailgate controlled by a hydraulic cylinder, a roll clamp and an additional platform located above the platform. The platform is tilted and equipped with barriers and rollers located across the loader. The additional platform rests on stops fixed on the racks connected by a beam and moves up to the limit switch mounted on the rack at a height of H = (1.1-1.2)Droll using a lifting mechanism. The mechanism consists of a hydraulic motor that rotates the shaft, cables and a braking mechanism. The shaft with drums is located under the platform floor, perpendicular to its longitudinal axis. The cables are passed through the rollers, fixed in pairs on the racks, and connect the corners of the additional platform with the drums. For barriers with height h = (1.6-2.0)Droll, a support wall is fixed above the tailgate. On the posts, at the height of the platform's upper location, there are latches controlled by electromagnets, above which a limit shield is installed on the front posts.

EFFECT: ability to load rolls in two levels.
