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, for example, small size and extraordinary flexibility and reach provide incredible access and capability, without sacrificing power.
In terms of power, the Brokk’s ability to use heavy duty attachments that normally need much heavier excavators makes it perfect for demanding tunneling work. For example, a 5-ton Brokk 400 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-ton breaker to do the job. Brokk machines are also the preferred tool for cross passages, substations, safety niches and lining renovations.
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 jobsite. Whether the job is below the sea, on the ground or at thousands of feet in altitude, a Brokk delivers where other machines cannot.
