Abstract
A riding sweeper is provided with a high dump mechanism for a dirt and debris receiving hopper of the sweeper. The dumping mechanism includes tracks located at forward side portions of the sweeper body. A carrier extends between the tracks and has rollers guided therein so that the carrier can move in an upright manner, preferably with the tracks slanting somewhat forwardly. A hopper is mounted on the back of the carrier and moves up and down therewith. A first fluid-operated ram is located between the sweeper body and the carrier for raising and lowering the carrier and the hopper. A second fluid-operated ram is located between the carrier and the hopper for tilting or rotating the hopper in an arcuate path to a dumping position after the carrier has been raised to an upper position. The hopper dumping mechanism includes a hydraulic system with a valve arrangement for stopping broom and vacuum blower motors when the hopper is raised.
