Sandvik Construction is introducing more advanced tunnelling drillrig instrumentation which, coupled with existing drill/blast design and control systems, brings higher levels of accuracy to standard jumbos. The TCAD+ system can be specified as an option for all Sandvik DT (tunnelling) and DD series (mining) drill-rigs, and even retrofitted to many other models, providing the boom joints have sufficient space for sensors. It succeeds the TCAD system with additional features. Read the press release and visit www.sandvik-construction.com. 20/15.
