Schmidt ｜Jet sweeper｜CJS-DI
- The robust and compact design is ideally matched to the MAN series chassis.
- The aerodynamic air flow ensures maximum blowing performance and reliable snow removal even at high speeds.
- The plough, sweeper unit and spreader or sprayer can be operated independently of each other. The choice of attachments can be largely customised to the specific requirements of the airport.
- The CJS-DI can be easily integrated into intelligent, digital support systems that ensure optimally efficient clearing and de-icing operations.
- The CJS-DI can be used with a variety of broom systems and automatic settings, as well as combined with ploughs individually adapted to the application scenario.
- With the CJS-DI, you can always react flexibly to changing requirements without having to compromise on performance.
- The training effort is significantly reduced with just one all-round vehicle.
- Drivers benefit from the comfort of the hydro-pneumatic three-axle chassis.
- Thanks to the extremely small turning circle, the CJS-DI also clears and de-ices in places where additional equipment would otherwise be required.
- The modern, intuitive operating concept allows many presets customised to your airport and operation with just one joystick.
- Proven in use: Both jet sweeper and attachments were first used over thirty years ago and have been continuously developed since then.
Clearing process
Back to blacktop in a single work step
Four process steps combined in a single operation and the runway is ready for flight operations again.
- The snow plough clears the majority of the snow to the side
- The brush roller clears away the remaining snow and slush
- The blower unit generates a powerful jet of air that sweeps across the entire sweeping width, removing any remaining moisture
- The build-up spreader/sprayer ensures de-icing or prevents against building
Snow plough
Clean and aggressive clearance is achieved with the Schmidt MS Tarron airport snow ploughs, such as the MS 56.2 N. These are designed for fast snow clearance at airports and offer outstanding performance with optional fine clearing bar, ejection stop or low blade shape.
Roller brush
The sweeping unit is mounted between the vehicle axles, while the sweeping roller drive is hydrostatic. The roller brush is optimally adapted to the sweeping surface and achieves a very good clearing result. The sweeping mirror of the roller brush is adjusted automatically and continuously via twin trailing wheels.
Brush designs
The CJS-DI has a 16-piece cartridge system with plastic [1], steel [2] or mixed bristles [3] and is also available as an 18 or 21-piece system. The 21-piece design produces less air turbulence with the denser bristle material, which ensures better clearing performance and a longer brush life at the same speed and with more brush strips.
Blower unit
The high-performance blower is driven hydraulically by the auxiliary engine via a variable displacement pump. The blower can be switched on and off by swivelling the pump. The blower unit is optimally designed to spread the large air capacity. The air speed is virtually constant across the entire working width. The blowing nozzle can be raised and lowered hydraulically.
Mounted spreader/sprayer
With the spreader/sprayer, de-icing can be delivered both preventively and curatively. The entire vehicle width is covered by a spray bar, while further working widths can be achieved with additional jet nozzles. The drive for the spreader/sprayer is provided by the carrier vehicle's hydraulics.
Carrier vehicles
As standard, the CJS-DI seamlessly mounts onto the MAN TGS 18.320 chassis type carrier vehicle. This carrier vehicle features a turning circle diameter of 18 meters and offers the option for additional rear axle steering for enhanced agility. The basic equipment and the exhaust emissions of the carrier vehicle must be selected specifically to meet the standards of the customer and the relevant country.
Drive
The drive motor drives the hydraulic pumps for operating and controlling the sweeping unit and blowing unit. The snow ploughand the mounted sprayer/spreader are controlled by a hydraulic system driven by the carrier vehicle's engine. The CJS-DI's hydropneumatic chassis offers the operator additional comfort in the field.
Motion control
Both impulse and synchronous control are possible for the snow plough, sweeping unit, blowerand rear mounted spreader/sprayer. On the one hand, this allows particularly efficient clearing processes via synchronous control. On the other, it also allows response to specific situations such as adjustment of the snow plough by means of individual, impulse control.
Display
State-of-the-art control technology is an important step in the safe and efficient clearing of airport tarmac. Logical and intuitive menu navigation and automatically controlled processes help to support drivers by ensuring that concentration remains focused on the clearing operation. The display indicates the operating hours data when the machine is at a standstill; information about the engine speed, brush speed and blower output can be called up when the engine is running. The display also provides a comprehensive overview of fault or error messages.
Smart Service Concept
The Smart Service Concept equals easier maintenance. It allows free access to all important components and low service time due to the ease of access to the components. In addition, the CJS-DI has a practical mounting bracket for the control panel on the control cabinet for service and workshop use. The optimised wiring harness layout ensures high quality standards and reduced service requirements. At the same time, the air intake underneath the bonnet ensures less air filter contamination.
