Sandvik Upgrades Roadheaders

Sandvik has upgraded its MT721 and MT521 tunneling roadheaders with several new features, aimed to further boost their excavation performance and customer profitability

Equipped with geometrically optimized transverse cutter heads the MT series, renowned for their cutting performance in a wide range of rock formations are flexible, robust and heavy duty machines that can be used for reliable excavation in a variety of underground civil construction applications.

The MT721 and the MT521 have now been future-proofed with new digitalization 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 harmonized for stable and reliable operation. 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.

“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 Digitalization, Mechanical Cutting Division, Sandvik Mining and Rock Solutions.
