Sandvik introduces the DS512i rock bolter

rock bolter

Sandvik Mining and Rock Technology has introduced its new DS512i rock bolter, which combines safety with performance. 

The Sandvik DS512i rock bolter offers improved safety and efficiency, and is equipped with a completely new carrier, high frequency rock drill, control system and ergonomic cabin.

The DS512i is also equipped with a new FOPS/ROPS cabin as standard, providing a safe, comfortable working environment for the operator, which reduces noise, vibration and dust levels, while improving visibility while drilling and tramming. 

Furthermore, the operating environment has an interactive graphic user interface enabling all bolting operations to be performed by a single operator.

The rock bolter’s intelligent control systems assist during drilling, grouting and bolt tightening, delivering high levels of automation. Machine efficiency is further maximized through easy to access service points from ground level, providing rapid maintenance and trouble shooting. 


The new rock bolter comes ready for the AutoMine fleet and information management system and has multiple levels of automation, enabling the correct choice of rig for the specific application.

The use of the Sandvik RD314 high frequency rock drill and the drilling control system optimizes drilling penetration rates. The one bolt automation function of the DS512i provides improved drilling productivity and extends operating lifetime of the drilling tools.

The new DS512i provides the ultimate peace of mind in rock support. With up to 55 per cent increased operator visibility and 35 per cent higher penetration rates for productivity and performance seamlessly combined.

More Sandvik news:

An upgraded bolting head comes with different bolt lengths providing an extensive bolt selection, while the eight-rock bolt carousel ensures that the DS512i is capable of installing different types of rock bolts ranging from 1.6 metres to 6 metres in length. 

As well, an automatic resin shooting and cement mixing system further guarantees a high-quality rock reinforcement process.

The rock bolter is able to carry a 1,200 kg cement silo, delivering increased meshing as well as hole angle measurement and an advanced boom manipulator. Bolting head movement is also optimized with new assistive and automatic features.

Mines or tunnels

Designed specifically for tunnelling and mining, the DS512i has been developed based on a modularized concept leading to high levels of parts commonality with the Sandvik DT922i, enabling lower levels of total cost of ownership. The bolter has been designed for the integration of subsequent actions involved in the drill and blast process.

The machine possesses several types of bolt length and varieties within the same machine and an automatic cement mixer in parallel with automatic resin injection. Ideal for small and large headings, it enables high bolting and meshing coverage, with efficient operations being ensured through sharing high commonality of parts with other members of the 400i carrier series.

Automation options

At the heart of the new DS512i are high levels of automation. These have been developed to suit the specific needs of the customers and come in two packages: Silver and Gold.

The Silver package comprises of ‘one bolt’ automation (collaring, drilling, grouting, bolt handling, tensioning) and hole angle measurement. The boom is fully instrumented with indicators for hole angles, tilt and rotation, as well as an advanced boom manipulator, automatic cement mixing and basic remote monitoring, amongst other features.

The Gold package has full instrumentation and fan bolt locations to show one or more bolt fans to the specific mine or tunnel coordinates. iSURE comes as standard along with MWD, Total Station Navigation, Tele-Remote bolting, ‘planned versus actual’ bolting (which can be transferred to the control system) and full remote monitoring.
