Brokk has introduced the Brokk 520D. Meeting both Tier 4 Final and Europe's Stage IV emission standards, Brokk says that the new machine is the most eco-friendly diesel demolition robot on the market. The 520D replaces the Brokk 400D, one of the first diesel models released, and comes equipped with Brokk's signature SmartConcept technology, boasting 40 percent more hitting power.
"Demand for diesel-powered machines has grown in recent years, especially from construction and demolition contractors who often need the extra power diesel-fueled machines can provide." said Martin Krupicka, Brokk Group CEO. "With a power increase and design enhancements, the Brokk 520D provides a power-packed solution that retains a relatively small footprint for its hitting force."
The Brokk 520D is the only diesel model out of the company's four new next generation remote-controlled demolition machines. Like the other next generation models, the 520D features Brokk's new SmartConcept system, including the SmartDesign and SmartRemote.
SmartDesign extends machine life and provides unprecedented ease of maintenance due to 70 percent fewer cables as well as hardened components, LED headlights and easily accessible grease points and hydraulic hoses. An ergonomic remote-control box, the SmartRemote, incorporates adjustable straps, intuitive controls and professional-grade radio technology with a 984-foot (300-metre) working range.
The 520D delivers 1,086 foot-pounds (1,472 joules) with each blow of its 1,510-pound (685-kilogram) BHB 705 hydraulic breaker. Its three-part arm extends to 23 feet (7 metres) vertically and 22 feet (6.7 metres) horizontally. It also rotates 360 degrees, giving operators optimal flexibility to reach nearly anywhere in one movement.
A heavy-duty boom system and increased hydraulics allow the diesel-powered machine to handle the same range of heavier, more powerful attachments including those available for the electric Brokk 500, released last year. This includes beam grapples, drum cutters, shotcrete nozzles, drills, planers, sorting grapples, demolition and scoop buckets, metal shears, clamshell buckets, concrete crushers and rock splitters.
