The new generation tractor semi-trailer PST-24 is a unified high-capacity semi-trailer on wide-profile tires for "BELARUS" tractors of 2-5 drawbar category class.

The main all-metal body with a back board opening with the help of hydraulic cylinders has a capacity for the transportation of medium density materials (ground, garbage, manure, finished silage, mineral fertilizers), taking into account the natural bulk cone (cap). In accordance to the order, for transportation of seeds of various crops, root crops, compound feeds, semi-trailers can be equipped with low extension boards and for lightweight loads with high extension boards.

The PST-24 three-axle semi-trailer has a front sprung axle with a drawbar, on which a MAZ wheel coupling device is mounted for coupling with the frame of the semi-trailer. The trolley loads the tractor trailer drawbar (about 2 t.) due to the displacement of the drawbar forward relative to the axis of the wheels.
