Pavement/surface sweeper having a simplified hydraulic system

摘要

A sweeper unit well-suited for use for sweeping paved areas includes a debris-retaining hopper with an associated fan assembly that includes an air outlet duct for connection to one side of a pick-up head and an inlet duct for connection between the other side of the pickup head and the debris-retaining hopper. A fan drive arrangement includes at least a first and a second hydraulic displacement device to drive the fan and, when required, provide a flow of hydraulic fluid for auxiliary devices including the gutter broom motor(s).
