ABSTRACT:
A pavement patcher has a frame supported on the back of a truck. An operator's platform is movable horizontally and transversely on the frame across the back of the truck, and longitudinally for a short distance. The platform carries a hydraulic control console and a blacktop hopper with a hydraulic rotor and an auger. The platform also carries a steel roller mounted on hydraulic rams. The truck driver stops with the frame over a hole. The operator riding on the platform positions the side delivery opening at the bottom of the hopper next to the hole and operates the auger to dispense the required amount of blacktop. The operator then extends the rams to lower the roller and moves the platform to roll the roller across the patch. Significant force is developed on the roller from the hopper's platform, carriage, frame and truck to seal the patch. A hydraulic package is mounted at a side of the frame with a motor, pump and reservoir.
