Sandvik Tunneling jumbos, DTi series

The computer-controlled Sandvik DTi series tunneling jumbos are designed to be fast, accurate, and user-friendly. They produce excavation results of the highest quality, with the lowest costs.

The series is available in five models for excavation of 12 - 232 sq.m (129 - 2497 sq. ft.) cross sections, including face drilling, bolt-hole drilling, and mechanized long-hole drilling.

The DTi jumbos are equipped with an advanced control system, powerful high-frequency RD525 rock drills, robust booms, and advanced drill string guides. They are meant for automatic use but allow the operator to finetune the process if the rock conditions so require. They also feature FOPS-certified, spacious 3i cabins that offer ultimate usability and excellent working conditions.
