S

Metal rail holding the rubber skirt around the suction head. Simplifies replacement and ensures an airtight seal along the edges.

Stencil for stop lines at junctions.

Chart correlating nozzle size pressure and travel speed. Used by operators to calculate correct binder application rate per m².

Strap keeping nozzle skirt taut for better sealing.

Acoustic silencer reducing overall sweeper noise levels.

Sensor detecting surface dampness before line marking or binder spraying. Prevents wasted material on non-adhesive wet substrates.

Gauge showing skirt wear limits.

Small roller at the front of the suction head that follows surface contours. Prevents the head from digging into uneven tarmac.

Field test using graded sand to determine macro-texture depth. Required on UK trunk-road surface-dressing sites to verify skid resistance.

Individually controlled valves for neat start/stop of spray lanes.
