The new 400 model machine features a bigger drive axis, rollers and sidetracks. It also has a larger undercarriage with new tracks that are 10% longer than its predecessor. This improves wear life for machines used in applications that require a lot of tracking and provides up to 60% greater stability when operating with heavier attachments. In addition, the machine’s outriggers provide a wide base that evenly distributes weight and provides even more stability. Its high chassis setup and heavy-duty rubber tracks make it easy to maneuver over rubble piles and obstacles.
The new Brokk 400 can handle attachments up to 1,420 lbs., and its hydraulic quick-hitch system eliminates the need for hard pinning, so operators can change attachments more quickly and easily and with less hassle.
When paired with Atlas Copco’s SB 552 hammer, the Brokk 400 has a hitting power of 773 ft.-lbs. at the tip of the tool, which makes it ideal for rock excavation in small tunnels, scaling or secondary breaking.
The new Brokk 400 weighs 11,240 lbs. and is 63 in. wide and nearly 81 in. tall. While it’s slightly larger than its predecessor it’s still compact enough for work in small spaces. It also is powered by a 30 kW electric motor for emissions-free operation in confined areas.
The machine features a robust, three-part boom that can operate at angles of up to 30 degrees and reach 22 ft. horizontally and 24 ft. 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 also features a box-weld design that provides additional protection for cylinders and hoses.
