Sandvik Mining and Rock Technology has launched the Sandvik DT1132i jumbo, an underground drill rig for tunnelling excavation.
When paired with the Sandvik RD535m a high-frequency rock drill, and rock tools designed for high-speed drilling, users have a heavy-duty solution for their underground drilling needs.
The three-boom, electro-hydraulic jumbo has a modular design making it flexible and versatile. It is suited for fast face drilling or mechanised long-hole drilling and bolting.
The computer-controlled rig uses both operator-controlled boom positioning and full-face automatic drilling functions.
It is capable of using automated drilling solutions, including the iSURE tunnel management software and SICA intelligent control system.
The drill is capable of delivering 20 per cent higher penetration rate, 25 per cent more side coverage, with 40 per cent less exhaust particles. This maximises power transfer capabilities leading to high drilling speed without compromised hole quality.
The rig includes an ergonomic vibration-dampened cabin designed for all-round visibility, low noise levels and minimised dust levels. It also includes diagnostic information that is integrated into one display to increase efficiency of the rig and the operator.
