Combustion engine casing
- Hydraulic lifting via control panel
- access to the engine and hydraulics
- Emergency lifting with a manual hydraulic pump
Roller brush
- The brush is supported by two rocker arms - during operation it moves on four wheels, independent from the cleaning machine frame, providing perfect adjustment to the surface.
- Brush lifting hydraulics is set in the floating position.
- Hydraulic brush drive
- Brush cartridge design enables fast replacement and easy maintenance. Cartridge replacement does not require shaft balancing.
- Brush path correction is manual in standard version, electric or hydraulic adjustment is optional.
Blowing fan
- Heavy duty fan – 8 m3/s – blowing the surface behind the brush roller
- Hydraulic drive
- Hydraulic lowering to the working position
- Directional diffuser with hydraulic control
- Left / right direction change coupled with brush direction change
Chassis
- Trailing axle of the rear suspension on pneumatic springs with adjustable stiffness for high cleaning and transport speeds.
- SAF axle is maintenance - free (inspection every 150,000 km).
Magnetic plate
- Removing ferromagnetic impurities from the surface
- Hydraulic lowering
- Easy plate cleaning
Additional information
- The cleaner is compatible with trucks, road tractors and tractors.
- Switching from operation to transport mode in several seconds with a single operator.
- Control of cleaner movement and emergency stop from the tractor cab.
- Hydraulic control of the gauge wheel for easy machine positioning at standstill.
- Pneumatic rear axle suspension for increased durability of all machine components.
- Easy machine operation and maintenance.
