Abstract: A material transfer vehicle has a frame, a front end including an asphalt paving material receiving device, and rear end including a discharge conveyor which is adapted to convey asphalt paving material to the receiving hopper of an asphalt paving machine. An operator's station includes an operator's platform on which is mounted an operator's seat. The operator's platform is moveable between a travel position that is entirely within the outer periphery of the material transfer vehicle and an operating position that locates the operator's seat at least partially outside the outer periphery of the material transfer vehicle.

Abstract: A milling machine for milling a surface of a roadway includes a frame and a milling assembly having a cutter drum that is mounted for rotation with respect to the frame. The cutter drum has a drive shaft on which a sheave is mounted. A primary drum drive assembly is adapted to rotate the cutter drum with respect to the frame. The primary drum drive assembly includes a drive belt that cooperates with the sheave on an input drive shaft for the cutter drum to rotate the cutter drum. A belt lift assembly may be operated to selectively disengage the drive belt from the sheave of the input drive shaft for the cutter drum, so that an auxiliary drum drive assembly comprising an auxiliary drive motor may be operated to rotate the cutter drum independently of the primary drum drive assembly.

Abstract: A CIR train includes a milling machine, an asphalt cement supply tank, a mechanism for dispensing asphalt cement onto paving material that has been removed from the roadway by the milling machine, an asphalt cement pump for pumping asphalt cement from the asphalt cement supply tank into and through an asphalt cement flow circuit to the asphalt cement dispensing mechanism. A heating assembly is interposed in the asphalt cement flow circuit between the asphalt cement supply tank and the dispensing mechanism. The heating assembly includes a heater and a heat modifying component. The heater includes an asphalt cement coil that is in the asphalt cement flow circuit, and a burner that is adapted to direct hot gases of combustion across the asphalt cement coil. The heat modifying component is adapted to modulate the amount of heat transfer from the hot gases of combustion to the asphalt cement in the coil.

Abstract: A vehicular sweeping machine includes a frame and a broom assembly that is mounted to the frame. The broom assembly includes a broom enclosure, a left hub that is mounted on a left hub mount arm, and a right hub that is mounted on a right hub mount arm. A broom is mounted between the left hub and the right hub. An outer tube is attached to the rear of the broom enclosure and to one of the left and right hub mount arms. An inner tube has a fixed end that is attached to the left or right hub mount arm to which the outer tube is not attached. The inner tube also has a free end that is adapted to slide within the outer tube. A linear actuator is attached between the broom enclosure and the left or right hub mount arm to which the fixed end of the inner tube is attached. The linear actuator is adapted to move the hub mount arm to which it is attached between an inner position in which the broom is engaged with the left hub and the right hub and an outer position in which the broom is disengaged from one or both of the left hub and the right hub.

Abstract: A chip sealing train for use in carrying out a chip sealing operation on a roadway using foamed asphalt cement includes a chip supply dump truck, an asphalt cement supply truck and a chip spreader. The chip spreader includes a receiving hopper for receiving stone chips from the raised dump bed of the chip supply dump truck and a spreader assembly which is adapted to dispense the stone chips onto the roadway. The chip sealing train includes a water tank and a foam dispersal assembly. The foam dispersal assembly includes a foaming chamber, an asphalt cement supply line that is in fluid communication with the asphalt cement supply truck and the foaming chamber, and an asphalt cement pump for pumping asphalt cement from the asphalt cement supply tank into the foaming chamber. The foam dispersal assembly also includes a water supply line that is in fluid communication with the water tank and the foaming chamber, and a water pump for pumping water from the water tank into the foaming chamber. A spray bar is adapted to dispense foamed asphalt cement from the foaming chamber onto the surface of the roadway in front of the spreader assembly.
