Tunnelling For efficient and profitable projects

Incredible access and capability

There is something special about Brokk and tunnels. The perfect combination of power, operability and accessibility makes this little giant the preferred choice for road, rail and subway tunnel projects across the world. In utility tunnels – such as cable and water tunnels – where space limitations make it impossible or impractical to use a larger machine. For tunnel enlargements and in other areas where Brokk machine’s remote-controlled operation, small size and extraordinary flexibility and reach provide incredible access and capability. Without sacrificing power.

And talking about power. The Brokk’s ability to use heavy duty attachments that normally need much heavier excavators makes the Brokk perfect for really demanding tunnelling work. For example, a Brokk 400 (weighing just 5 tons) with a half-ton breaker gives you an unparalleled size-to-power ratio, outperforming excavators up to five times as big. And if that still isn’t enough, there is always the Brokk 800 with its 1,2 tons breaker to do the job. Brokk machines are also the preferred tool for cross passages, substations, safety niches, lining renovation etc.

With a wide range of attachments, the Brokk machine easily handles a full range of tasks such as drilling, rock breaking, excavating, scaling, rock splitting, removal of debris, and even shotcreting. The Brokk robot is really one machine for all tasks, which will save on both machine investment costs and set up times at the work site. Whether the job is below the sea, on the ground or at thousands of feet in altitude, a Brokk delivers where other machines cannot.
