ABSTRACT:
A street sweeping vehicle has a motor and drive system for propelling it forward. It also has several auxiliary devices including a main broom, a gutter broom, and a debris elevating system, each of which is powered by a separate hydraulic motor. Each hydraulic motor receives its energy from a pump that is in turn driven by a main motor of the vehicle. In each auxiliary device, the separate hydraulic motor which powers that device is so positioned as to operate effectively while permitting necessary position adjustments of the driven mechanism to take place and also minimizing wear and tear on the mechanism.
