Abstract: A spreading device for confined application of grain type materials along a well-defined path on a road from a conveyor of a storing tank mounted on a moving vehicle includes a chute member mounted thereon that receives the materials from the conveyor and substantially drops them generally vertically under gravity on the road along the path in proximity and in front of a roller. The latter stops the materials relative to the road and confines, or packs, them on the road. The spreading device is adapted to be mounted on either side of the vehicle, in line with its wheels.
Abstract: A grit spreader for motor vehicles consists of a container (1) for the gritting material, a dispersion channel leading to a vehicle wheel and an endless conveyor (5). The conveyor (5) is disposed in a first horizontal section (2) of the dispersion channel and is divided into individual chambers (9) by transverse webs (8). The discharge end of the conveyor (5) lies above a second section (3) of the dispersion channel comprising the outlet (4) and which leads to the vehicle wheel and is closable by means of a flap (16). The drive unit (10) of the conveyor (5) is provided with a follow-up control which only stops the drive unit (10) following actuation of a cutout switch when a transverse web (8) of the conveyor (5) enters the upper return section (A) of the conveyor pulley (7) disposed at the discharge end.
