Aluminum belt-discharge bodies configured for installation on frames of straight truck or trailer chassis used in construction materials hauling. The use of aluminum provides substantial weight savings, which allows for an increase in the payload that can be hauled by the truck to the paving machine. The belt bodies also feature a wider unloading belt as compared to conventional steel live-bottom trucks, which increases efficiency, reduces unloading time and generates faster cycle times. The wider bottom lowers the center of gravity of the vehicle, resulting in more stability and safety. Furthermore, a wider body with sloped side walls reduces and/or eliminates the effects of transportation segregation of the asphalt or aggregate being hauled. Belt-discharge bodies according to the invention effectively remix the material being hauled as it is unloaded.

A spreader assembly may include a hopper configured for receiving a spreadable material, a removable cartridge configured for sliding engagement with the hopper and having a material transportation mechanism configured for receiving the spreadable material from the hopper, and a spreader configured for receiving the spreadable material from the material transportation mechanism and spreading the spreadable material onto a target surface. One of the hopper and the cartridge may include a roller having a roller surface, and the other of the hopper and the cartridge may include a bearing surface configured for rolling engagement with the roller surface.

The disclosure relates to a road paver that comprises a tractor with a material hopper and a machine frame. The machine frame is pivotably connected to the paving screed by pulling arms and a material spreading auger is disposed in a gap between the tractor and the paving screed. A longitudinal conveyor device extends through a tunnel between the material hopper and the gap. The road paver according to the disclosure is characterized by a spraying device that is configured for injecting a liquid into the gap between the tractor and the paving screed or into the tunnel or into the material hopper.

An asphalt finisher is provided that includes a tractor; a hopper mounted on a front side of the tractor; a conveyor that conveys a paving material in the hopper to a rear side of the tractor; a screw that spreads the paving material, which is scattered on a road surface by the conveyor, in a vehicle width direction; a screed device that lays and levels the paving material, which is spread by the screw, at a rear side of the screw; an actuator that drives at least one selected from the group consisting of the tractor, the conveyor, the screw, and the screed device using electric power; a power storage unit; and a power supply unit that is connectable to an external device and can receive electric power supplied from the external device.

An aggregate spreading system includes a dump truck that has a cab and a bed. The bed may contain an aggregate. A transport unit is coupled to the dump truck. The transport unit is positioned on the bed to urge the aggregate forwardly in the bed. A distribution unit is coupled to the dump truck. The distribution unit is positioned on the bed to receive the aggregate from the transport unit. Thus, the distribution unit distributes the aggregate onto a support surface. The distribution unit levels the aggregate on the support surface when the aggregate has been released onto the support surface.

Systems and methods for applying roadway surface treatments. The system has an aggregate application assembly and a resin application assembly that are mounted or otherwise secured to a truck or other vehicle. The resin application assembly is spaced from the aggregate application assembly in the direction of travel of the vehicle. As the vehicle moves along a roadway surface, the resin and aggregate can be continuously applied such that the aggregate is provided to portions of the roadway surface that have been covered with resin.

A conveyor system adapted for use on an asphalt paver comprising a conveyor system frame, a first pulley that is rotatably mounted to the frame, a second pulley that is rotatably mounted to the frame and spaced apart from the first pulley, and a belt having a pulley-contacting surface and an asphalt-contacting surface and being disposed around the first pulley and the second pulley. The preferred conveyor system also comprises a wiper that is adapted to remove asphaltic material from the asphalt-contacting surface of the belt and a means for rotating the first pulley that is adapted to rotate the first pulley. The preferred conveyor system is adapted to convey asphaltic material between a first area adjacent to the second pulley and a second area adjacent to the first pulley. A method for conveying asphaltic material in a paver comprising providing a conveyor system and conveying asphaltic material.

A spreader assembly for spreading sand or salt comprised of a molded, double-walled hopper having a bin portion and leg portions. The hopper has an inner wall and an outer wall, wherein the inner wall has a front end section and opposing side sections. The end sections and the side sections define a media-holding chamber within the bin portion of the hopper. The chamber has a generally rectangular upper portion, a funnel-shaped lower portion and a bottom having an opening extending through the bin portion. The funnel-shaped lower portion of the chamber slopes toward the opening. The outer wall of the hopper defines the leg portions, and the leg portions are dimensioned to extend below the opening in the bin portion.

The disclosure shows an exemplary system for unloading and distributing bulk materials. In one embodiment, a powered conveyor system including a conveyor belt is coupled with the bed of a truck. There may be one or more wings attached to the truck bed for directing the flow of a bulk material from the truck with the conveyor system. Various other embodiments implement different types of vehicles for transporting bulk material.

A conveyor system adapted for use on an asphalt paver comprising a conveyor system frame, a first pulley that is rotatably mounted to the frame, a second pulley that is rotatably mounted to the frame and spaced apart from the first pulley, and a belt having a pulley-contacting surface and an asphalt-contacting surface and being disposed around the first pulley and the second pulley. The preferred conveyor system also comprises a wiper that is adapted to remove asphaltic material from the asphalt-contacting surface of the belt and a means for rotating the first pulley that is adapted to rotate the first pulley. The preferred conveyor system is adapted to convey asphaltic material between a first area adjacent to the second pulley and a second area adjacent to the first pulley. A method for conveying asphaltic material in a paver comprising providing a conveyor system and conveying asphaltic material.
