FLEXIBILITY FOR EVERY<br />
OCCASION:<br />
Surface mining, the established<br />
mechanical process<br />
for extracting material,<br />
manages without<br />
drilling, blasting and primary<br />
crushing. Instead,<br />
Surface Miners have a<br />
special cutting drum for<br />
cutting and crushing the<br />
rock, which is then loaded<br />
onto dumpers via stable<br />
conveyor systems in a<br />
single operation. Alternatively,<br />
the rock can also<br />
be dropped alongside the<br />
machine. It is also possible<br />
to deposit the material<br />
in a windrow between the<br />
crawler tracks. Wirtgen is<br />
the only manufacturer to<br />
offer all options.<br />
CUTTING TECHNOLOGIES<br />
EQUIPPED FOR AN EFFICIENT FUTURE<br />
The new technologies from Wirtgen make for maximum cutting tool utilization.<br />
HT15 QUICK-CHANGE TOOLHOLDER SYSTEM: Wirtgen, the<br />
leading innovator, has developed the new HT15 quick-change<br />
toolholder system. Unique the world over, this system simplifies<br />
toolholder changing and cuts the time required for the job from<br />
between 60 and 90 minutes to just 10 to 15 minutes. The system<br />
was specifically developed for Surface Miners and increases<br />
both the productivity and the availability of the machines.<br />
WIRTGEN PICK INSPECTION (WPI): The WPI measuring system<br />
for Surface Miners detects the wear on the cutting tools.<br />
Sensors in the cutting drum housing measure the degree of wear<br />
of the picks in next to no time. The worn picks are highlighted<br />
in colour on a separate, mobile terminal. WPI enables mining<br />
companies to optimally plan service intervals, avoid downtimes<br />
and thus save costs.
