The Brokk Pedestal Boom pairs Brokk’s three part arm system with 360o slewing for versatility in underground applications. The unit can be operated with either a tethered remote or from a control room. Depending on network configuration, the machine can be manoeuvred from over 2,000m away using video monitoring and operation to increase safety and efficiency. At the same time it features a rugged design and compact footprint continuing Brokk’s tradition of powerful solutions for confined spaces. The new development, along with other solutions, was displayed at MINExpo, 13 – 15 September, in Las Vegas, at Brokk’s booth 1155 in the North Hall.

“Brokk saw an opportunity to give our customers a better solution for breaking oversize rock in crushing and grizzly applications. We’ve developed technology that is powerful, compact, flexible and easy to install,” said Martin Krupicka, president and CEO of Brokk Group. “The new Brokk Pedestal Boom provides a plug and play solution that is perfect for underground spaces with low headroom or other space constraints. We are leveraging our 45 years of experience and proven technology platforms to create a smart, safe and user friendly solution.”

The Pedestal Boom is based on the proven arm system and power pack of Brokk’s demolition robots. The machine body is then mounted on a pedestal, rather than tracks. This allows the machine to be installed in a stationary position next to a crusher or any area where primary breaking is needed. Unlike existing breaker boom options, Brokk says its Pedestal Boom system integrates the power source and arm for a compact breaking solution with just a single power cable. No external power pack or hydraulic hose connection is needed. Model sizes for the range include the 200, 300, 500 and the 900 Pedestal Boom, with the latter capable of producing 3,050J/Nm at a rate of 330-680b/min with the ‘BHB 1500’ breaker. 

In addition to a streamlined design for easy setup, the Pedestal Boom offers flexibility in underground and confined space applications. Its three part arm design allows users to reach closer to crushers and manoeuvre in as little as 180cm of height clearance. This, paired with the unit’s slewing capabilities, means operators can maintain the best angle against the material for efficient breaking. The compact and flexible three arm system also makes maintenance and switching attachments easier, especially in areas with space constraints.

All systems are remotely operated and feature Brokk’s ‘SmartRemote’ technology. The ‘Standard Remote Operation’ solution features ergonomic remote control, intuitive controls and professional grade radio technology with a 300m working range. Additionally, ‘Networked Remote Operation’ allow operators to control the robot while sitting in an office, which depending on network configuration, can be located over 2,000m away. The machine is connected and operated over Ethernet or Wi-Fi. The standard video option includes two cameras on the machine and an ergonomic operator’s desk with integrated controls and video screen. Upgrades are available including additional cameras for better visuals and optical zoom cameras. One control system can be paired with up to six Brokk Pedestal Boom systems.

The Pedestal Boom comes standard with a corresponding BHB hydraulic breaker for optimal efficiency and breaking capacity. Brokk says its design enables operators to use 100% of the breaker’s potential with minimal wear and tear on the carrier with the same applying to the new Pedestal Boom product range. In addition to the breaker, the Brokk Pedestal Boom works with grapples, drilling attachments, and more.

“Worker safety is a major focus for many companies and Brokk actively searches for ways to make every aspect of our customers’ processes safer,” Krupicka said. “Over the years, our demolition robots have helped mechanise a number of high risk, heavy labour tasks such as scaling, drilling and secondary breaking. The new Brokk Pedestal Boom range addresses one more challenge, enabling customers to efficiently complete work without any health and safety risks.”
