In confined spaces, size limitations can make it hard to maximize a demolition machine’s power and productivity. Brokk’s new line of remote-controlled demolition machines offer significantly improved power-to-weight ratios, while maintaining similar dimensions. The new models increase hitting power by 40 per cent, thanks to a new system that boosts the power coming from the motor by regulating the output, pushing out more energy in short bursts. “We’re not taking constant power from the motor, we’re taking intermittent power,” said Peter Bigwood, Brokk’s vice-president of sales. “So we’ve developed software to take more when we need it.” The smaller models use an electric powertrain, while the largest uses a diesel engine with improved fuel efficiency. Although they are designed for construction, the company said they are ideal for any confined space. Various attachments to the robotic arms can be used for crushing, drilling or digging rock, allowing it to be used for both tunnelling and processing. The machines are typically controlled from a distance of 25 metres by radio, although they have a 300-metre control range. The electric models are powered by cord from the mine power grid.
