GUTTER BROOM
FUNCTION
As a complement to the REGENERATIVE AIR SYSTEM, the gutter broom is designed to dig
material loose from the gutter or similar areas and move it in front of the pick-up head where
it can be easily picked up by the air sweeping action of the pick-up head. The gutter broom
is designed to hydraulically relieve and fl ex up and over or in-and-out around stationary
obstacles. When not in use, the gutter broom is retracted under the cab, off the pavement,
and hydraulically locked in position. The remote tilt option provides the operator with the
capability of adjusting the gutter broom to the pitch of the surface being swept without the use
of hand tools or the need to exit the cab.
