New From Brokk: 4 Machines, 8 Breakers

Published: 19/3, 2019

Brokk chose World of Concrete 2019 to make its largest-ever North American product debut, introducing four new remote-controlled demolition machines complemented by an eight-model line of customized breakers.

All modelsÑthe 1.6-ton Brokk 170, the 2-ton Model 200, the 3-ton Model 300, and the 5-ton Model 520 diesel all feature BrokkÕs three-part SmartConceptª system, which ensures improved performance and uptime. 

SmartPower senses when the power supply is poor or faulty, then compensates before damage to components occurs. This allows contractors to use the machine with generators or unreliable power sources. SmartDesign extends machine life and provides unprecedented ease of maintenance due to 70% fewer cables, hardened components, LED headlights and easily accessible grease points and hydraulic hoses. An ergonomic remote-control, the SmartRemote, incorporates adjustable straps, intuitive controls and professional-grade radio technology with a 984-ft (300-m) working range.

The Brokk 170, offers 15% more power than its predecessor, the Brokk 160, but retains the same compact dimensions. The three-part arm extends to 16 ft (4.8 m) vertically and 14 ft (4.4 m) horizontally. The machine also features 360 degrees of continuous rotation for optimal versatility on the jobsite. 

The a 36.8-hp (27.5-kW) Brokk 200 packs the power of a 3-ton Brokk machine into a 2-ton package, plus 15% longer vertical and horizontal reach in a compact footprint similar to the Brokk 170. The extra chassis length and machine weight ensures proper balance, even when wielding heavy attachments such as breakers, drum cutters, grapple, and concrete crushers. The Brokk 200 is ideal for heavy duty, difficult-to-access projects and applications and represents the new standard in compact remote-controlled power.

The Brokk 300 features 40% more demolition power than its predecessor, the Brokk 280. Like its predecessor, the mid-sized Brokk 300 is just 47.2 in (1.2 m) wide but can handle larger attachments weighing as much as 1,102 lb (500 kg).  The three-part arm extends to 21 ft (6.5 m) vertically and 20 ft (6 m) horizontally. The arm also rotates 360 degrees for optimal flexibility. 

Topping the offerings is the Brook 520 Diesel, successor to the Brokk 400D. Meeting both Tier 4 Final and European's Stage IV emission standards, the new machine is the most eco-friendly diesel demolition robot on the market. 

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.Ó says 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 520D has a reach of 23 ft (7 m) vertically and 22 ft (6.7 m) horizontally. 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. 

Every Brokk model, new and existing, is ready to be matched with the company's new BHB hydraulic breaker series. 

ÒAs an industry leader in compact demolition, it makes sense for us to introduce our own lineup of powerful hydraulic breakers to match the high strength and performance of Brokk demolition machines, Krupicka says. Our customers benefit from the greater productivity, efficiency and quality that comes with the pairing of Brokk breakers and machines.

The BHB series includes eight breaker models, starting with the 110-lb (50-kg) BHB 55 breaker for the compact Brokk 60 remote-controlled demolition machine. The range goes all the way up to the 1,543-lb (700-kg) BHB 705 for the recently introduced Brokk 500 and Brokk 520D.

In essence, each of the new robot models is designed from the attachment backward, providing the exact amount of flow, pressure, backpressure, and downward force that the hammer requires, which offers the best possible demolition performance to Brokk customers.

For example, pairing a new Brokk 200 with a 650-lb (295-kg) BHB 305 breaker increases the unitÕs hitting power by 40%, with 450 lbf (610J) with each blow. Similarly, the Brokk 520D delivers 1,086 lbf (1,472 J) with each blow of its 1,510-lb (685-kg) BHB 705 hydraulic breaker.

Like Brokk remote-controlled demolition machines, the BHB series features a high power-to-weight ratio. The attachments are lightweight and compact, yet feature power similar to larger, heavier breakers from other manufacturers. The hammer bodies are machined from a solid casting, eliminating side and through bolts, along with the side plates found on many other hammer designs. An integrated, side-mounted accumulator holds a nitrogen gas charge for as long as a year.
