ABSTRACT:
An improved pavement patching vehicle includes a movable distribution hopper and a supply hopper having an opening for discharging patching material into an underlying distribution hopper. The supply hopper, heated by catalytic radiant panels, includes a bottom, sidewalls and a pivotal hood. The supply hopper is mounted to the vehicle by a pair of lift arms and a pair of support arms. The lift arms are secured to a common lift shaft mounted to the vehicle parallel to the vehicle axis. The lift shaft is driven by a single piston and cylinder combination mounted generally parallel to the vehicle axis through a gear drive. This drive is compact due to positioning of the piston and cylinder combination.
