A conveyor assembly is for use with a vehicle having a wheel pivotable about an axis and an actuator configured to pivot the wheel. The conveyor assembly includes a carriage connectable with the vehicle and having a wheel pivotable about an axis, a swing axis and a first bearing surface about the swing axis. A carriage steering actuator pivots the carriage wheel about its axis in one direction when the vehicle actuator pivots the vehicle wheel about its axis in an opposing direction. A conveyor connected with the carriage has a second bearing surface engaged about the first bearing surface. Further, a swing actuator rotates the conveyor about the swing axis such that the second bearing surface linearly displaces along a first arcuate path as an actuator end displaces along a second arcuate path, configured such that the bearing surface displacement is greater than the actuator end displacement.

A swing conveyor assembly for use with a base vehicle including a first material conveyor having a discharge location. The swing conveyor assembly comprises a platform supported by a wheel assembly, a linkage assembly adapted to be interconnected between the platform and the base vehicle and a second material conveyor. The linkage assembly is configured to permit free vertical movement over a given range of the platform and wheel assembly relative to the base vehicle. The second material conveyor has a receiving location and is rotatably connected to the platform about a vertical rotation axis. The rotation axis extends through the receiving location and the discharge location when the platform is connected to the base vehicle such that receiving location remains aligned with the discharge location as the second material conveyor is rotated relative to the first material conveyor.

A pneumatic fumes collection system for an auger-type distributing device that spreads hot asphalt behind a mobile paver includes a rotatable auger shaft extending horizontally above a surface being paved and laterally to a longitudinal centerline axis of the paver. The shaft includes a plurality of auger flights spaced therealong, and can be raised and lowered to a plurality of elevations above the surface being paved. A fumes intake inlet is positioned above, and in a fixed spacial relation to, the auger shaft, whereby the fumes inlet raises and lowers simultaneously with the auger shaft, resulting in an a more uniform fumes collection over a plurality of auger flight elevations. A fumes exhaust fan and exhaust stack are positioned on the paver.
