Schmidt | Sweeper |TJS – Towed Jet Sweeper
Clearing process
Back to blacktop in a single work step. Three process steps combined in a single operation:
1.The snow plough clears the majority of the snow to the side.
2.The brush clears away the remaining snow and slush.
3.The blower unit generates a powerful air flow across the entire sweeping width, removing any remaining moisture. And, with that, the runway is ready for flight operations.
Sweeping unit
The hydraulically-driven brush is mounted to a supporting frame and suspended via a parallelogram lifting system, so that it rests on the surface regardless of vehicle movement and uneven ground. The brush’s automatic and stepless sweeping pattern adjustment is carried out hydraulically and determined by the height adjustment of twin castors. During operation, the brush speed is adjusted automatically to suit the driving speed and shown on the control panel’s display. A long brush service life is possible – thanks to the wear-dependent brush speed adjustment.
Optimum brush life
Otimum brush life is achieved with a 21-piece cassette brush set with the longest bristle length. This type of brush is the most economical based on the number of cassettes to brush cost ratio – a recommendation we are happy to share with you.
Another plus
Depending on your requirements, you can choose between plastic (polyurethane) bristle materials, steel or mixed (polyurethane/steel).
Blower unit
The blower unit of the TJS is located directly behind the sweeping unit. There is next-to-no performance loss, since the air flow is dispersed directly above the ground. The blower removes any remaining water and slush from the clearing area, ensuring optimum friction values and better braking action on runways. The blower is driven hydraulically by the auxiliary engine via a variable displacement pump, and blower speed can be regulated in two stages, making optimum use of performance. The aerodynamic air flow also offers optimum blower performance over the entire clearing area. A constant air speed across the entire working width ensures uniform clearing of the snow-covered area.
Control system
State-of-the-art control technology is an important step in the safe and efficient clearing of airport operation areas. Logical and intuitive menu navigation and automatically controlled processes help to support drivers by ensuring that concentration remains focused on the clearing operation.
