Redesigned Brokk 400 Remote-Controlled Demolition Machine

Brokk has upgraded its electric Brokk 400 remote-controlled demolition machine to include a larger undercarriage for heavy-tracking applications, such as tunneling and mining, and for enhanced stability when operating with heavier attachments including metal shears and scabblers.

Brokk 400An improved hydraulic system provides more efficient fluid flow when the machine is operating a drill attachment, delivering more consistent power. The new 400 features a bigger drive axis, rollers and sidetracks. It has a larger undercarriage with tracks that are 10 percent longer than its predecessor. This improves wear life in applications that require a lot of tracking and provides up to 60 percent greater stability when operating with heavier attachments. The machine’s outriggers provide a wide base to evenly distribute weight for additional stability. Its high chassis setup and heavy-duty rubber tracks make it easy to maneuver over rubble piles and obstacles.

The 400 can handle attachments up to 1,420 pounds, uses a hydraulic quick-hitch system so operators can change attachments easily. Paired with Atlas Copco’s SB 552 hammer, it has a hitting power of 773 foot-pounds at the tip of the tool. The 11,240pound machine is 63 inches wide, nearly 81 inches tall and is powered by a 30 kW electric motor. The three-part boom can operate at angles of up to 30 degrees and reach 22 feet horizontally and 24 feet vertically. The remote-controlled boom allows operators standing a safe distance away to reach into areas that traditional machines or users with handheld equipment cannot. The boom features a box-weld design to help protect cylinders and hoses.
