Three generations of stabilisers

IMG 2894 MediumIn East and West Africa numerous BOMAG stabilisers (and recyclers) are currently working on jobsites of all ranges and applications, fully serviced by the exclusive BOMAG dealers in the respective countries

From car parks, roads, landfill sites and dam construction to industrial areas, major highways, railway tracks and airports – BOMAG soil stabilisers and recyclers are used on a wide variety of applications. The unique, global product range is designed for varied fields of application such as crushing asphalt, soil stabilisation, or cold recycling. 

One large project was successfully implemented with BOMAG machines in North Bavaria, Germany, where one of the largest industrial park expansions in Germany is currently under construction. The contract for the earthworks for the automotive supplier and technology park in Hof-Gattendorf was awarded to ARGE AMAND Bau Sachsen GmbH & Co. KG together with AMAND Bau NRW GmbH & Co. KG. From the end of July to mid-November, approx. 150,000 m³ of topsoil and around 680,000 m³ of soil is being moved, paved and stabilised over a total area of 50 hectares. Only the best subgrade achieves optimum load bearing capacity for infrastructure and buildings. Consequently, soil stabilisers are being deployed to improve a large part of the 680,000 m³ with binding agents.

To achieve the required daily performance targets at the Hof-Gattendorf project, up to 580 t of binding agents need to be spread daily and milled into 13,000 m³ of soil. MEIER Bodenstabilisierung opted for three large BOMAG planers from their own fleet in order to meet the deadlines and required quality. In addition to the machines’ performance, Jan Meier, managing director of MEIER Bodenstabilisierung, sees other reasons to tackle such a major project with BOMAG equipment. He said, “We have been a customer of BOMAG for more than 25 years and looked after by the Chemnitz branch throughout this period. That builds trust.”

For this reason, three machine generations were used simultaneously in the project on the A93 motorway: an MPH 125, an MPH 600 and an RS 650. One thing all the machines have in common is, for example, the permanent 4x4 allwheel drive for best traction on very soft ground, as is the case with the Hof-Gattendorf project. When the specified daily output is as demanding as here, it is important to work fast.

In addition to time pressure, the weather is an unpredictable factor. The more it rains, the more slippery and soft the ground becomes, which increases the demands on the stabilisers. The combinable articulated and rear-wheel steering on each machine generation ensures flexibility and maximum manoeuvrability for any ground condition. The height-adjustable cab has also been retained, ensuring the driver’s comfort and clear overview. The swivel and sliding seat provides the operator with an individual sitting position and thus optimum all-round visibility. Visibility is improved even further by four fixed cameras.

The visual differences between the MPH 125, MPH 600 and RS 650 first become apparent in the exhaust systems. Due to the new engines, the RS 650 with its 8- cylinder Deutz engine has a power output of 650 hp, while the two predecessors each mix the soil with 600 hp.

The continuous improvements in engine technology also led to the introduction of stricter exhaust emission standards, which include significantly reduced limits for nitric oxides and particles. The latest generation of engines meets these environmental requirements. With the aid of a double SCR exhaust system, nitric oxides are converted into nitrogen and water by adding urea solution (AdBlue) and thus rendered harmless.

All three machines are equipped with BOMAG’s FLEXMIX system. This makes it possible to optimally adjust the milling performance and mixing level of the different soils on site. Thanks to continuous improvements in the tool exchange holders and their arrangement on the rotors, the working speed and service life have also further increased. 

Hydraulic reversible fans keep the radiators clean for longer. Compressed air connections for tools and hydraulic turning devices for the rotor save time and greatly facilitate the daily inspection and replacement of cutting tools. The latest machine generation also provides the best possible lighting conditions thanks to 8 LED headlights.
