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.
The twin castors offer very quiet, vibration-free and smooth sweeping performance, while level snow ejection and the cleanest fine clearing ensure maximum safety. This is achieved thanks to aerodynamic spoiler guidance, automatic spoiler adjustment and wear-dependent brush speed adjustment. This permits the jet sweeper to deliver a specific fine clearing result, while the robust design offers both optimum operational capability and maximum safety.
Another plus:
Depending on your requirements, you can choose between plastic (polyurethane) bristle materials [1], mixed (polyurethane/steel) [3] or steel [2].

Blower unit
The blower unit of the TJS/TJS-C 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.

Difference between TJS and TJS-C

The TJS – where you choose the towing vehicle.
The TJS includes an all-wheel-drive towing vehicle with front-mounted snow plough and a jet sweeper with integrated coupling system – either as a semi-trailer or as a trailer. The auxiliary engine, which drives both the sweeping unit and the blower unit hydraulically, is located in the rear engine compartment.
The TJS-C – the perfect choice if you need a complete solution.
The compact TJS-C has a powerful tractor unit, including a snow plough, plus the same options for the brush roller and blower unit as the TJS. The compact attachment to the tractor unit makes the TJS-C a compact and particularly manoeuvrable machine.
The TJS-C’s environmentally-friendly drive technology.
Airports are facing growing challenges due to environmental and climate protection, which is why we focus on innovations that avoid pollutants and CO₂ emissions in the development of our machines. The use of environmentally-friendly engines for the TJS series is an excellent example of this approach. To match the required performance with low fuel consumption, we use Volvo’s dual fuel,CO₂-neutral engines, powered by a mixture of biogas and biodiesel. The dual fuel system means the engines make an important contribution to an airport’s positive environmental assessment. With biogas, 60%-80% of the biodiesel can be substituted depending on the load, while HVO (hydrated vegetable oil) can be used as an alternative fuel.

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.
Both impulse and synchronous control are possible for the snow plough, sweeping unit and blower, so all components can be controlled individually or synchronously. On the one hand, this allows particularly efficient clearing processes (synchronous control). On the other, it also allows response to specific situations, such as adjustment of the snow plough, by means of manual control (impulse).
The display indicates the operating hours when the machine is at standstill; information about the engine speed, brush revolution speed and blower performance can be called up when the engine is running. The display also provides a comprehensive overview of fault or error messages.
