Side Brush

The side brush is a critical component of mechanical road sweepers, consisting of a cylindrical brush assembly mounted on a rotating arm or fixed bracket at the vehicle's side. It operates perpendicular to the main sweeper broom, extending the cleaning width and effectively removing debris from curbs, gutters, and hard-to-reach areas. The brush rotates at controlled speeds (typically 50-150 RPM) to sweep particulate matter, leaves, sand, and litter toward the central suction or collection system. Its design includes adjustable height and angle mechanisms to accommodate varying road surfaces and debris types while minimizing wear and optimizing cleaning efficiency.

The side brush operates on rotational kinetic energy transferred from a hydraulic or electric motor through a gearbox or direct drive system. As the brush rotates, its bristles make contact with the ground surface at a calculated angle (usually 15-30 degrees from vertical), creating a sweeping motion that lifts and propels debris inward toward the main collection area. The brush's rotational direction (typically clockwise on right-side mounts, counterclockwise on left-side mounts) creates a vortex effect that enhances debris capture. Pressure sensors and automatic retraction systems prevent damage from obstacles while maintaining consistent ground contact.
