Brokk has revised its 400 model to boost performance

The upgraded electric Brokk 400 demolition tool now benefits from a larger undercarriage for heavy-tracking applications. This remote-controlled demolition machine also has a new hydraulic system, with more efficient fluid flow when the machine is operating a drill attachment.

The new 400 model machine features a bigger drive axis, rollers and sidetracks. The new tracks are 10% longer than before, improving 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 are said to provide a wide base that evenly distributes weight and provides even more stability. The new 7571 Brokk 400 can handle attachments up to 645kg, while the hydraulic quick-hitch allows operators to change attachments quickly.

When fitted with 161 Atlas Copco’s SB552 hammer, the Brokk 400 can be used for rock excavation in small tunnels, scaling or secondary breaking. The Brokk 400 weighs 5.2tonnes and is 1.6m wide and nearly 3.2m tall, with power from a 30kW engine.

The machine features a three-part boom that can operate at angles of up to 30° and reach 6.7m horizontally and 7.3m vertically. The remote-controlled boom allows operators to stand a safe distance away. The company also builds custom machines with special equipment such as cameras, extended arms, side-angling devices and cable drums.
