Atlas Copco says its new MB 750 medium-duty hydraulic breaker has the highest output-to-weight ratio in its weight class. The breaker is powered by a combination of oil and gas, allowing it to recover energy by maximizing the recoil effect. The company says this boosts its output power, which results in less fuel consumption during operation. A double retainer bar system and DustProtector II help extend the breaker’s service life.
