DT923i

Sandvik DT923i is an automated tunneling i-series jumbo with two electro-hydraulic booms, equipped for fully-automated face drilling. It achieves high-performance and precise drilling through different automation levels.

Features

SB110i instrumented boom

SB110i instrumented boom provides up to 62% more side coverage. Harness fully proportional boom control for swift manual boom handling, securing operational savings while tunneling.
Rod handling system

Sandvik SRH is an automatic rod-handling system designed for safe longhole drilling while tunneling. It uses GT38 MF extension rods with an optimal hole size of 64 mm. Applications include the drilling of injection and probe hole fans heading from the tunnel face forward.
Boom collision prevention

The collision avoidance system enhances automatic boom movement reliability by detecting potential collisions with other booms or carriers. It prevents collisions while ensuring consistent production rates, due to dynamic route recalculations.
