Abstract (en)

[origin: WO9708984A1] A brush pressure control system for a cleaning, sweeping or scrubbing machine comprising a machine frame supporting a brush head (8), an actuator (10) for raising and lowering the brush head, mounted between the frame and the brush head, an elongate balance beam (32) pivotally connected to the frame (30) and connected at one end to the actuator for movement therewith, and at the other end having a counterbalance mass (35) mounted thereon. The pressure control system (24) is particularly useful for a pedestrian operated machine but may be applied to a ride-on machine too. The improvement allows the system to operate more effectively particularly over low ranges of pressure such as that corresponding to the weight of the brush head itself and it allows for a floating head system over a wide range or pressures. The counterbalance mass (35) is advantageously equivalent to the mass of the brush head (8) and a parallelogram linkage (38) may be provided between the frame and the brush head to keep the brush head generally horizontally positioned. A potentiometer may register the movement of the balance beam as the brush head is raised or lowered so as to provide an indication of brush wear.
