AT Pipe Umbrella Kit

AT - Pipe Umbrella Kit

AT Pipe Umbrella System, developed by Sandvik company DSI Underground, is an optional kit for selected underground drills, including DT923i, DT1132i and DT1232i. Pipe umbrella systems are a pre-support measure used in weak ground conditions that install pipes into the ground to construct an umbrella or canopy, creating immediate reliable support and reducing the risk of hazards.

Efficient self-drilling installation

The casing provides immediate support compared to other systems that require additional working steps.

Robust system

A solid system and high-strength pipe connection contribute to a fast and reliable installation. The hydraulically-driven squeezing unit is mounted on a console installed on the jumbo’s drill feed, allowing the umbrella pipes to be connected quickly and securely.  

Advanced technology

The groundbreaking squeezed connection technology is the result of cutting-edge design, leading to a safer, faster remote-controlled pipe connection process, improved load-bearing capacity and optimized quality and utilization rate.
