Sandvik's MT series roadheaders, equipped with geometrically optimised transverse cutterheads, can be used for excavation in a variety of underground civil construction applications.
Sandvik MT721 and Sandvik MT521 have now been future-proofed with new digitalisation and automation features.
One of the major upgrades is the new machine control system, which has more power and is designed for future applications. The software code has been simplified and harmonised for stable and reliable operation. Sandvik says the new SafePLC improves machine safety and is extendable for additional developments.
The new machine control system will fully integrate all future digital services, including tele-remote operation as well as Racoon for machine telemetry data collection and digital customer services platform SmartMate.
Sandvik says the MT721 is the only roadheader on the market that uses ICUTROC technology for seamless cutting in challenging hard rock conditions. Another key feature in both roadheader models is the CUTRONIC automated cutting technology for reliable and fast rock excavation with high profile accuracy. It is now also suitable for geometrically complex tunneling applications.
The new Sandvik boom control includes new optimised machine control software and upgraded machine hydraulics for fast tunnel excavation and accurate tunnel profiling.
“We are extremely proud of these new tunneling roadheaders, which will set the standard for reliable, productive and sustainable mechanical rock excavation, and continue our journey towards being able to deliver our customers fully autonomous mechanical rock excavation machines,” said Uwe Restner, product manager roadheaders and digitalisation, Mechanical Cutting Division, Sandvik Mining and Rock Solutions.
