Brokk’s C20 rock splitter

Brokk, a manufacturer of remote-controlled demolition machines, recently introduced its C20 rock splitter to the market.

The attachment, made by Brokk’s German sister company, Darda, offers contractors a safe, quiet alternative to explosives and hydraulic breakers, according to Brokk. The tool increases productivity in industries such as mining, quarrying, tunneling, construction and demolition.

“We never stop looking for ways to improve safety with our machines,” says Lars Lindgren, Brokk president. “Paired with a Brokk 280 demolition robot and counter weight, the C20 rock splitter allows our customers to split rock with all the speed and effectiveness of breakers and chippers, but without the noise, vibration and danger common with that type of equipment.”

The C20 rock splitter comes in four models – two vertical options ranging from 64 to 72 in. long, as well as two horizontal options from 70 to 83 in. long.

The C20 rock splitter quickly breaks large boulders and solid rock in mining and shaft-sinking applications, as well as cross-passage work in tunneling. Contractors drill a 3-in.-diameter hole into the rock with a separate attachment before inserting the splitter. According to Brokk, the attachment expands with as much as 1,800 tons of force, splitting the rock.
