Lots of know-how in the milling and mixing rotor

Geared for tough operations

The milling and mixing rotor – core element of the tractor-towed stabilizer – can optionally be equipped with the tried-and-tested quickchange toolholder system HT22 for tough everyday operation on the construction site. With this system, WIRTGEN builds on its experience of many years in cutting technology. A precisely defined arrangement of the cutting tools on the rotor ensures smooth machine behaviour and perfect milling and mixing results.

The quickchange toolholder system significantly reduces operating costs of the machine.

Ample storage space for tools or wearing parts.

Ample storage space for tools or wearing parts.

Additional marks in favour of this system are optimum tool rotation, extremely low wear and tear, easy tool replacement, and easy monitoring of the degree of wear of the upper toolholder parts. The intelligently arranged toolholders allow sufficient space for the material to be stabilized. The mode of operation minimizes material stress, which extends the useful life and improves the profitability of the entire machine. The pneumatic tool extractor and easily accessible rotor enable cutting tools to be replaced quickly and conveniently.

Efficient mechanical belt drive

Translating power into productivity

The success of our tractor-towed stabilizers is guaranteed by their ability to thoroughly mix even the heaviest soils. This is ensured by the powerful, mechanically driven milling and mixing rotor, which homogenizes the material effectively across the full working width and evenly mixes in the pre-spread binding agents, such as lime or cement.

Powerful belt drive for full power at working depths of up to 500 mm.

Belt drives are arranged on both sides of the milling and mixing rotor. This dual drive concept is very efficient in translating engine power into milling performance. In addition, the eccentric rotor gearbox causes the pulley housing to always remain above the ground. The stabilizer’s intelligent drive concept has the positive side effect of reducing the tractor’s fuel consumption. The spring-loaded belt tensioner ensures optimum transmission of power at all times.

Market-leading and cutting-edge products for the Road and Mineral Technologies business sectors are constructed at the WIRTGEN brand headquarters in Windhagen, Rhineland-Palatinate. With its innovative, high-performance and cost-efficient products and technologies for cold milling, soil stabilization, hot and cold recycling, concrete paving and surface mining, WIRTGEN leads the world market in road construction and repair, as well as in mining natural rock and pay minerals.
