SAJA - Tufted Steel Wire Cassette for Runway Sweepers

SHARE
The Tufted Steel Wire Cassette by SAJA is designed to enhance the performance of runway sweepers by efficiently managing debris across diverse surfaces, including ice, snow, and foreign object debris. Crafted from bundles of high-quality galvanized steel wire, it ensures optimal functionality and longevity. The cassettes are tailored to fit the brush cores of various manufacturers, providing a full sweeping width and easy assembly. Made with thermoplastic elastomer bushings and polyethylene core, the cassettes withstand harsh conditions, maintaining flexibility even at low temperatures like -35°C. This feature is validated through rigorous testing in extreme Finnish weather conditions. Moreover, SAJA cassettes feature a secured locking wire and are compatible with a broad range of sweeper brands such as AEBI SCHMIDT, BOSCHUNG, FRESIA, and others. Certified under the ISO9001:2015 Quality Management System, these cassettes guarantee high-quality manufacturing and are available in various set configurations for quick and reliable assembly.

The profile on SAJA® tufted brush cassette is filled with bundles of galvanized steel wire. Sturdy construction ensures peak performance in the maintenance of runways, taxiways and other paved areas – no matter if there is ice, snow, rubber, or FOD on the surface. Tufted steel wire cassette is available in various profiles and lengths to fit the brush core of the sweeper.

The length of SAJA® brush cassettes is optimized for the brush core of each runway sweeper and sweeper-blower manufacturer. With just the right fit, you achieve the full sweeping width for your machine.

We use steel wires only from the most recognized suppliers, to ensure the highest standards and steady quality. Steel wire is galvanized to withstand chemicals used for the runways and taxiways. Single wires have 3-dimension corrugation to prevent the wires to break in rpm’s up to 1250.

Material used in the bushings is ”thermoplastic elastomer”, in order to ensure the highest durability in most demanding weather conditions and physical stress. The bushing retains its flexibility even in very low temperatures. The material has been tested in Finland’s rough winter conditions for example in Ivalo, Enontekiö and Kittilä Airports, where the temperature can easily reach -35 degrees Celcius.

The core of the cassette is made of Polyethylene for many reasons. As the bushings, also the profile endures low temperatures down to -35 degrees, which is mandatory in Scandinavian winter conditions. Polyethylene (HDPE) provides high stiffness in combination with outstanding impact strength even at very low temperatures. Plastic core is also lighter compared with metal ones to minimize the load of the broom shaft and its bearings.

Steel Wire

  • Highest quality of microstructure and physical properties
  • High-carbon steel wire with 2-axis crimping

Zinc-coating

  • Diameter either 0,45 mm or 0,60 mm as per request
  • Wires per tuft 200, 240, 280, 290 pcs or anything between, as per request

Bushings

  • Thermoplastic elastomer
  • Flexible even in low temperatures

Profile

  • Frost resistant Polyethylene (HDPE)
  • Customised shape according to the brush core
  • Customised length according to the brush core

Custom Fit Length
No more cutting oversized cassettes, no more extra pieces for filling the row. The lenght of SAJA® cassette is chosen according to the length of your brush core for your convenience. 

Secured Locking Wire
No more flanges, screws, twists, glue or other tricks to fix the locking wire to the profile to keep the wires at place. Our 4 mm locking wire is inserted permanently. Feel free to try removing it. 

Weather Proof Bushings
Bushings made out of common plastic staying intact after sweeping at 1250 RPM in -35­ °C (-31 °F)? We don`t think so either. We use Thermoplastic elastomer to keep the flexibility at all weathers.

Wires with High Durability
Leaving pieces of wire behind instead of cleaning the runway? Therefore we use only galvanized wires of highest quality from the most recognized suppliers with tensile strenght range more than 2350 N/mm² for best performance.
