    • Fully integrated into the machine management system
    • Many newly added complementary and automated features
    • Milling depth measurement via displacement sensors in the hydraulic cylinders of the side plates
    • Ultrasonic sensor integrated in the telescoping levelling arm, left

    Additional Information

  2. Dynamic and quick manoeuvring

    • Travel speed of up to 12 km / h
    • Swift steering using the steering wheel
    • Highly precise steering via the fingertip steering feature integrated in the multifunctional armrest
    • Reversing with the milling drum switched on
  3. Best-in-class productivity

    • Tremendous engine power at maximum torque
    • State-of-the-art engine control to minimize diesel consumption
    • Three different milling drum speed options
    • Hydraulically engaging power belt tensioner
  4. High traction ensured by optimum weight distribution

    • Variable supplementary weights of up to 1,000 kg
    • Extremely low centre of gravity
    • Centrally arranged water and diesel tanks in neutral position
    • High machine stability in both three-wheel and four-wheel design
  5. High loading capacity for maximum performance

    • Extra-large belt width of 350 mm and cleat height of 25 mm for high conveying capacity
    • Wide conveyor slewing angles
    • Hydraulic folding conveyor for quick folding during operation on site
    • Quick-release coupling for easy mounting and removal of the discharge conveyor

    Additional Information

  6. Superior cutting technology boosts performance

    • Wear-resistant HT08 toolholder system
    • Minimum distance between machine edge and milling edge to minimize non-milled strips
    • Hydraulically lifting side plates with proactive floating feature causing the side plates to be lifted automatically in loose ground
    • Automatic raising of scraper by means of an overload sensor
    • Scraper disconnected from loading conveyor to allow partial loading even at the maximum milling depth
    • Broom to clean the milled surface

    Additional Information

  7. Efficient multifunctional armrest

    • Ergonomically designed multifunctional armrest with colour control screen
    • Additional machine height adjustment feature included in the multifunctional armrest
    • Display of job data on the control screen
    • User-programmable “Favourites” keys

    Additional Information

  8. Perfection in visibility, comfort and ergonomic design

    • Perfect view of the side plates, left and right
    • High-quality camera system to provide a direct view of important work processes
    • Ergonomically designed comfort driver’s seat including seat heating
  9. Effective steering features

    • Wide offset front wheels
    • Extremely large locking angle of the front wheels
    • Automatic self-steering feature for the right-hand rear wheel
  10. Quick pivoting of the right hand rear wheel

    • Quick, automatic pivoting of the right-hand rear wheel without lowering the milling drum to the ground
    • Safe and firm locking in end position
    • Heavy-duty friction bearing

Small milling machines are equipped with wheel units and a milling drum arranged at the rear of the machine. A slewing conveyor is also arranged at the rear of the machine, accepting the asphalt material granulated by the rotating milling drum and discharging it directly onto waiting trucks. This is why small milling machines are also called rear loaders. The compact rear loaders have been designed for one-man operation. In addition, they are usually extremely manoeuvrable machines, and their right-hand rear wheel can be pivoted in front of the milling drum. Engine performance in this machine class ranges from approx. 40 kW / 55 PS to appr ox. 160 kW / 220 PS.
