Device for applying and spreading hot asphalt over roads has supply hopper underneath a thermo container outlet and provided with height adjustable skids to adjust incline to reach road edges

摘要

The device has a built-in slide carriage with supply hopper (1) mounted underneath a thermo-container outlet (16). The trapezoidal hopper has close to the ground on the right and left two inner and outer skids (2) arranged at the sides and a third vertically adjustable skid which is located inside the hopper. The slide carriage is connected by longitudinal guide rods (10) to a trailer rail (4) with inner rollers (8) and by a hydraulic cylinder (6)to the traction vehicle (15). The transversal displacement forces on the longitudinal guide rods are stabilised by two diagonal struts. An inclined draw bar (3) at the back in the work direction lies inclined to the drive direction. The height adjustment of the outer skids is through a spindle screw (9) to adapt to the relevant particle size of the asphalt mixture.
