Sandvik’s new DS512i 5m x 5m rock bolter

Swedish mining and rock technology manufacturer Sandvik has unveiled the DS512i rock bolter, designed for 5m by 5m headings.

The company says the rig was designed specifically for tunneling and mining and was developed based on a modularised concept, leading to high levels of parts commonality with the Sandvik DT922i, reducing the cost of ownership.

The machine is equipped with a new carrier, high frequency rock drill, control system and an enhanced cabin, giving it, says Sandvik, improved levels of safety and efficiency.

Sandvik says the new rig offers 35% higher penetration rates than its predecessor, and features an upgraded bolting head, with different bolt lengths, plus an eight-rock bolt carousel, allowing for the installation of bolts from 1.6cm to 6m in length.

An automatic resin-shooting and cement-mixing system further enhances the rock reinforcement process. The bolting head movement also has standard assistive and automatic features.

The DS512i is able to carry a 1,200kg cement silo and delivers increased meshing as well as hole angle measurement and a boom manipulator.

The new FOPS/ROPS cabin reduces noise, vibration and dust levels and promises up to 55% greater visibility than the previous model.

Sandvik says the rig has high levels of automation, which come in two packages: Silver and Gold.
