MILLING TOOLS FOR SOIL STABILISATION
Soil stabilisation, a process widely used throughout the world, is the ideal solution for producing compactable soil with good paving properties from a sub-base with insufficient bearing capacity. In this context, companies need to be able to process a wide variety of soil types, from "highly cohesive" to "interspersed with coarse rock" to"abrasive". Wirtgen develops milling tools specifically for these applications. The company's range of picks for soil stabilisation now also includes Wirtgen Compact Carbide (WCC) milling tools.

For soil interspersed with stones
Due to their shape and materials, Wirtgen's newly developed WCC milling tools are perfect for mixing of cohesive soils interspersed with large pieces of rock. They have a highly wear-resistant carbide cutting edge that is nearly unbreakable and therefore impact-resistant due to the enormous strength of the material.

Depending on their application, WCC milling tools is a useful addition to the existing range of point-attack cutting tools with Generation Z being the all-rounder for cold recycling and soil stabilisation. Even the hardest base courses and soils can be economically processed with these point-attack cutting tools.

TORQUE SAFELY UNDER CONTROL
The B&R ACOPOS P3 servo drive is now also available with safety function, Safely Limited Torque (SLT). This makes B&R one of the first manufacturers to offer this certified safety function. SLT safely monitors torque up to SIL 2 / PL d.

The torque is limited to the configured maximum value with the aid of current measurement integrated directly in the drive system. Since the safety function runs decentrally in the drive, an extremely short maximum fault detection time of 8 ms is guaranteed. Particularly when combined with other safety functions such as Safely Limited Speed or Safe Direction, the SLT function facilitates safe collaboration between human operators and their machines.

The risk of operators being injured due to pinching or crushing while working on a machine is minimised.

Safe prevention of mechanical overload
SLT can also be used to safely limit the load on mechanical systems. In this way, the safety function acts like a torque wrench that prevents over-tightening of screws. SLT can therefore be used as a protective measure against overloading drive axes and brakes. As a result, it is possible to use less expensive mechanical components since there is no need to account for torque spikes.
