Tunneling jumbos

Sandvik tunneling jumbos are designed to drill out the face quickly, accurately and efficiently. Built on tough diesel-driven carriers, they are electro-hydraulically powered and equipped with 2-3 booms, long feeds, extremely fast hydraulic rock drills and advanced drilling control systems. With face coverage areas from 12 - 211 sq. m (129 - 2271 sq. ft), all booms and feeds have automatic parallel holding with quick look-out auxiliaries for accurate hole placement, optimal profiling and minimal overbreak.

News Sandvik iSURE® is a new, revolutionary tunneling project management and information analysis tool for optimizing the drilling and blasting patterns. It gives specific guidance for different stages of drilling and blasting, keeping project costs low, and guaranteeing smooth proceeding of the tunneling work. Read more about iSURE Tunneling jumbos Sandvik DTi series tunneling jumbos are designed to be fast, accurate and user-friendly. They produce excavation result of the highest quality, with the lowest costs. The series is available in four models for excavation of 12 - 211 sq.m (129 - 2271 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 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.
