Sweep System, Side Broom
Functional Description
Overview
The side broom sweep system is available with either with a single left-hand side broom (with right side
scrub brush), or with dual side brooms. Both configurations use DustGuard
™
nozzles to spray solution in
front of the broom(s) to minimize dust.
The side broom hydraulic motors are powered by the oil from the discharge side of the two main scrub brush
motors. The side sweep/scrub solenoid valve S8 controls the oil flow to the side broom hydraulic motor(s).
The side broom(s) use an electric lift actuator to raise and lower the broom(s).
