Abstract
Vehicle including, mounted on a chassis, a device for receiving material to be spread, a device for transferring the material towards a spreading component, a tank for binding product, a distribution bar, and a motorization assembly. The chassis includes at a rear portion, after the component for spreading the material, and mounted on rollers or balls that are rotatable independent of rolling elements mounted on a front portion, at least one of the motorization assembly, the tank and a control and transmission mechanism providing weight to the rear portion to permit the rear portion to act as a compactor.
Claims22
A road vehicle for spreading of materials for repair of a highway, comprising:
- a carrier chassis mounted on rolling elements having associated therewith;
- a device for receiving material;
- a device for transferring the material towards a component for spreading the material over the highway;
- a component for spreading the material over the highway;
- a tank for product for binding the material onto the highway;
- a binding-product distribution bar positioned in front of the spreading component;
- a motorization assembly;
- a unit for driving the vehicle;
- a front portion of said chassis being mounted on rolling elements;
- hydraulic control and transmission means connecting said motorization assembly to said rolling elements and to said unit for driving the vehicle;
- and
- a rear portion of said chassis being positioned in back of said component for spreading the material, said rear portion of said chassis being mounted on rollers or balls that are rotatable independently of said rolling elements connected to said motorization assembly and mounted on said front portion of the chassis, and said rear portion of said chassis having positioned thereon at least one of said motorization assembly, said tank, and said hydraulic control and transmission means, whereby weight of said at least one of said motorization assembly, said tank and said hydraulic control and transmission means is exerted on said rear portion of said chassis to form a compactor of materials spread over the highway.
