optimally designed for flexible use in soil stabilisation and road and path construction.

With working widths of 2.5m and a milling depth of up to 40cm and 50cm respectively, the tractor-towed stabilisers are “power-packed machines” driven by the rear PTO shaft of a powerful tractor with 200-300hp or 300-450hp, said Bomag.

The global road equipment major added that the tractor-towed stabilisers are new additions to its product range and their design is based on “numerous tried-and-tested technologies and many years of experience in the field”.

According to Bomag, modern tractors are versatile pulling and driving machines, and, in combination with optimally matched attachments, they are constantly opening up new areas of application and can even be used for heavy earthmoving work. The new Bomag RS 250 and RS 300 tractor-towed stabilisers can now fill a void in the fleets of construction companies and service providers looking for a flexible and economical tractor solution for milling, stabilising and mixing soils, said the manufacturer.

Bomag added that the light and manoeuvrable systems are the perfect complements, especially on smaller construction sites, but not just there. They ensure even better utilisation of tractors, which have become indispensable on modern construction sites due to their versatility and flexibility. One core application scenario is soil stabilisation: the tractor can now be used universally and flexibly to pull a binder spreader, water tank or tractor-towed stabiliser.

Sebastian Ibald, product manager at Bomag, explained: “When stabilising, there is no need to replace non-load-bearing soils. Stabilising is therefore usually the better choice, both economically and ecologically, compared to removing reusable soils. By mixing in binders such as lime, this method removes moisture from the soil on site, thus improving its compaction properties and load-bearing capacity. Through the precisely dosed addition of cement and water as a hydration shell, even non-load-bearing soils can easily be made permanently load-bearing, firm and frost-resistant.

“With our new tractor-towed stabilisers, the highly efficient Bomag technology for milling, mixing and stabilising can now be used even more easily and flexibly on smaller construction sites. Optimised power transmission and high-performance cutting technology meet sophisticated and maintenance-friendly holder systems. They guarantee maximum milling performance, uniformly smooth surfaces after milling and comparatively low fuel consumption."

Available in two power classes, the RS 300 (for tractors with 300-450hp) is suitable for larger applications in stabilisation, soil improvement and road construction. The lighter and even more compact RS 250 for tractors from 200-300hp is a good choice in road construction, for building embankments or slopes, and for backfilling, Bomag said.

Unlike Bomag’s familiar large, self-propelled stabilisers/planers, the new tractor-towed stabilisers rely on the tractor as the prime mover and are driven by the rear PTO shaft at an input speed of 1,000min-1. Coupling is via the three-point hitch (category 3 or 4). On the RS 250, the milling depth of up to 40cm can be easily and variably adjusted using the hydraulic lower link.
