Multinational remote-controlled demolition machines manufacturer Brokk has launched its own line of hydraulic breakers.
The new Brokk Hydraulic Breaker (BHB) series is matched with the company’s full range of remote-controlled demolition robots.
Each robot is essentially designed from the attachment backward, providing the exact amount of flow, pressure, back pressure and downward force that the hammer requires. This offers the best possible demolition performance to Brokk customers.
Brokk highlighted the new series at World of Concrete 2019, in Las Vegas, the US, and bauma 2019, in Munich, Germany.
“As an industry leader in compact demolition, it makes sense for us to introduce our own line-up of powerful hydraulic breakers to match the high strength and performance of Brokk demolition machines. Our customers benefit from the greater productivity, efficiency and quality that comes with the pairing of Brokk breakers and machines” says Brokk Group president and CEO Martin Krupicka.
The BHB series includes eight breaker models, which starts with the 50 kg BHB 55 breaker for the compact Brokk 60 remote-controlled demolition machine. The range goes all the way up to the 700 kg BHB 705 for the Brokk 500, introduced in 2017, and Brokk 520D, released in April last year.
Like the 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.
Brokk demolition robots and breakers are designed to work at maximum performance together, resulting in more total demolition power. Brokk engineers its demolition machines starting at the tip of the breaker for maximum compatibility.
This includes reducing back pressure and optimising machine oil flow, oil pressure and down pressure to allow for more hydraulic power while using less energy.
The result is that Brokk demolition robots provide some of the highest power-to-weight ratios in the industry, allowing contractors to substitute robots for larger excavators, and achieve the same concrete removal rates.
