Abstract:
The invention concerns a method for actuating binder diffusers of a sparge pipe (1) and/or front closure plates dispensing chippings of a diffuser-spreader (2) borne by a vehicle (3). The method is characterised in that it essentially consists in: actuating, in phase shift, the binder diffusers and/or the front closure plates dispensing chippings using means (4) for projecting on the road surface (5), a target image (6) which moves simultaneously with the vehicle; actuating the sequential opening and closure of the binder diffusers using a single control lever such as a joystick.
Abstract:
A spraying surface treatment vehicle comprising a binder spray unit and an aggregate spray unit which are arranged in the mentioned order in the front-to-rear direction of the vehicle at the portion of the vehicle which is ahead of front wheels thereof, or at the portion of the vehicle which is between front and rear wheels thereof, or at the portion of the vehicle which is at the back of the rear wheels thereof, whereby a spraying surface treatment method comprising carrying out a total surface treatment consisting of at least the spraying of the binder and that of the aggregate with the vehicle driven forward continuously is attained, the method enabling a uniform and highly durable surface treatment layer to be formed efficiently in a short period of time.
Abstract:
A truck (10) includes a dump body (12), a truck frame (24) with a rear axle (26), a lift system (30), and a conveying system (22). The dump body (12) is defined by a unitary floor (18), a pair of sidewalls (14, 16) which extend up from opposite sides of the floor (18), and a front wall (13) and a back wall (20) located on opposite sides of the floor (18) and extending between the sidewalls (14, 16). The dump body (12) is pivotally connected to the truck frame (24) adjacent to the back wall (20). The lift system (30) is mounted to the truck frame (24) and the dump body (12) for lifting an end of the dump body (12) proximate the front wall (13) between a lowered resting position on the truck frame (24) and an upper raised position. The conveying system (22) is positioned on the floor (18) behind the rear axle (26) and extends between the pair of sidewalls (14, 16). The dump body (12) has at least one opening (68) in alignement with the conveying system (22).
Abstract:
A container (1) for transporting bulk material, such as gravel or asphalt with fractions of varying particle sizes, has at least in a discharge portion a symmetrical bottom wall and inwardly inclined side walls. The discharge is meant to take place by raising the main portion of the container relatively the discharge portion. According to the invention the trough-shaped bottom wall is provided with a discharge outlet (10) having its greatest extension at the centre of the discharge outlet and narrowing therefrom towards the sides, so that the flow of material will be less at the sides than at the centre of the discharge outlet, the discharge outlet facing essentially downwards when the main portion of the container has been raised into its discharge position.
Abstract:
A material spreading system including a spreader (50) and a tote (10), and related methods, are disclosed. The spreader may include a frame attachable to a loading machine such as a skid loader, an inlet for receiving a material, one or more connector members, and a discharge mechanism configured to selectively discharge the material onto the ground. The tote (10) may include a container for storing the material and one or more connector members. The connector members of the tote may be configured to matingly engage the connector members of the spreader such that an opening in the container aligns with the inlet of the spreader. Accordingly, the material in the container may be transferred from the container to the spreader (50). Furthermore, the material spreading system may be used in various application including those involving the spread of granular and/or liquid de-icing material over the ground.
Abstract:
A spreader assembly for the controlled delivery to a surface of granular materials such as aggregates from a hopper in communication with a source of the materials external to said assembly; wherein the assembly comprises; an opening to said hopper which receives said materials from said materials source, a discharge opening from the hopper; a gate or gates adjacent said discharge opening; control means for adjusting the rate and or quantity (weight or volume) of said materials delivered from said hopper; wherein the control means includes means to receive at least one input parameter and means to convert said at least one input parameter into an output parameter for performing at least one mechanical activity in the assembly; wherein the rate or quantity at which said material is delivered is dependent upon the at least one input parameter and said mechanical activity.

Revêtement des chaussées.
Abstract:
An apparatus for unloading bulk material, particularly asphalt and the like, from the deck (3) of a load-carrying vehicle, and spreading the material (49) over ground (37) contiguous to the vehicle, includes a spreader unit connectable for support to the rear end of the deck (3). The unit comprises a part (5) arranged for connection to the end of the deck for receiving material from the deck, and with the aid of a transverse conveyor (7) to give this material a suitably agitated or comminuted state and convey it further, and a cantilever arm-like conveyor (9), adapted at its first end to receive the material conveyed according to the above and at its second free end to discharge received material, the conveyor (9) being controllably swivelably suspended (at 11) at said first end, so that it can be caused to sweep over ground (37) contiguous to the vehicle, thereby to spread the discharged material (49) over said ground.
