ABSTRACT:
The specification discloses a mechanical sweeper having a roller brush which throws rubbish forward in the direction of travel into a collecting hopper. The hopper is mounted in a fork carried by a lifting arm and the arrangement is such that actuation of the lifting arm does not cause tipping of the hopper. Separate means are provided for tipping the hopper at any desired moment during lifting.
