FIELD: transportation.
SUBSTANCE: sand spreading device is made in the form of the trailer bogie and contains a frame, a handrail, the wheels and a container for sand. The trailer bogie has the possibility of the planar movement along the required trajectory. In the lower part of the container there is the gap, adjustable in width by the bafflers, with the hollow or stepped shaft located inside its plane. The elastic flexible tape plates or brushes are fixed on the outer generatrix of the shaft surface parallel to its axis. In this case, the shaft by means of the bearings has the mechanical locking by the check stopper connection to the vehicle wheels, which are rigidly connected to each other by the shaft, passing inside the hollow shaft.
EFFECT: sand spreading intensification.
