Wirtgen integrated "S-Pack" Spreader Module in Recycling Machinery

WINDHAGEN/GERMANY, October 2, 2014 - In its recycling and soil stabilization product division, Wirtgen provides an unrivaled range of mobile machines and systems for a whole variety of applications. The "S-Pack" (spreader pack) allows binding agent to be spread without generating clouds of dust; this addition to the construction machinery manufacturer's product range creates new opportunities for optimizing the range of applications and cost-efficiency.  

Used on motorways, in residential areas, on industrial estates and on difficult terrain – recyclers and soil stabilizers are confronted with an extremely varied range of situations. In many cases, contractors face additional challenges due to strict emission standards, for instance in nature conservation areas. A solution is now available for these applications too, namely the "S-Pack" for the WR 240/WR 240i/WR 250 models from Wirtgen.

Cost-efficient spreading without dust: Lower emission levels, enhanced safety

Using the integrated spreader module, a WR with "S-Pack" spreads the binding agent directly in front of the milling and mixing rotor which immediately mixes it into the soil. The closed drum housing and an additional double curtain of rubber matting prevents the formation of dust clouds and ensures that the material is exclusively spread inside the milled cut. Thanks to the integrated spreader module, binding agent can now be spread regardless of wind and weather and without drifting or displacement due to vehicles driving ahead or passing by. Materials such as cement or lime must be spread safely and precisely and processed without emissions. This is particularly true in sensitive areas such as industrial estates that are subject to restrictions on account of food production facilities or areas near airports. This applies especially to motorways, where drifting must be avoided in order to avoid endangering the flow of traffic.

quick refilling of the Wirtgen WR

The binding agent tank is located directly above the milling and mixing rotor of the Wirtgen WR; the diesel tank is over the rear wheels. A few minutes is all it take to refill with binding agent. A conventional silo vehicle containing around 27 t can easily be emptied by the "S-Pack" within the space of just two hours. | photo: Wirtgen GmbH

Making light work of difficult terrain

Wirtgen's most powerful WR models, the WR 240/WR 240i and WR 250, are predominantly used on rough ground and soils with insufficient bearing capacity. Wherever other machines come up against their limits, the two recyclers and soil stabilizers bring their tremendous off-road mobility into play, and they now can also be used in combination with the integrated spreader module. As a result, jobs can be completed rapidly, utilizing a minimum of machinery and personnel and hence minimizing transport costs, too.

With the Wirtgen "S-Pack", the spreading quantity is adjusted via just a few buttons on the clearly structured control display. In this way, the driver always has a perfect overview of the work process and remains in full control at all times. | photo: Wirtgen GmbH

Clear operation and process control

Operation of the integrated spreading system and diagnosis of the work process are extremely simple intuitive actions effected via the control display in the driver's cabin. The machine operator is in control of the mixing process at all times and can adapt the metered quantity to the current situation.
