Sandvik DS512i Rock Bolter

The rock bolter DS512i for 5m x 5m size headings from Sandvik Mining and Rock Technology is equipped with a completely new carrier, high frequency rock drill, control system and ergonomic cabin, the Sandvik DS512i offers high levels of safety and efficiency for all rock reinforcement operations.

The DS512i is equipped with the new FOPS / ROPS cabin as standard. This reduces noise, vibration and dust levels and improves visibility while drilling and tramming. An interactive graphic user interface enables all bolting operations to be performed by a single operator in safety.

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. High levels of drilling performance are ensured, thanks to the use of the Sandvik RD314 high frequency rock drill and the drilling control system which optimizes drilling penetration rates.

The eight-rock bolt carousel ensures that the DS512i is capable of installing different types of rock bolts ranging from 1.6m (5’) to 6m (20’) in length. An automatic resin shooting and cement mixing system further guarantees a high quality rock reinforcement process. Able to carry a 1200 kg cement silo, the DS512i delivers increased meshing as well as hole angle measurement and an advanced boom manipulator. Designed specifically for tunneling 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.

Automation Features

The automation features come in two packages. 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 (Measurement-While-Drilling), Total Station Navigation, Tele-Remote bolting, “planned versus actual” bolting (which can be transferred to the control system) and full remote monitoring.
