Excavators are the most common carrier for hydraulic rock breakers and excavator hammer attachments across construction, mining, and demolition sites in Australia. Selecting the right excavator for your rock breaker setup depends on carrier weight class, hydraulic flow rate, operating pressure, and the application, whether you're breaking reinforced concrete on a residential site or primary rock in a quarry. DOZCO supplies hydraulic breakers for excavators across the full weight spectrum, from 0.5-ton mini excavators through to 60-ton mining machines. Every excavator rock breaker in the DOZCO range is engineered to match the hydraulic output and structural capacity of its target excavator class, ensuring maximum impact energy without overloading the carrier or causing premature wear.
Whether you operate a Caterpillar excavator on a Melbourne demolition site, a Komatsu machine in a Western Australian quarry, or a Hitachi excavator on civil infrastructure in Sydney, DOZCO has a hydraulic excavator breaker built to fit your fleet and perform reliably under Australian conditions.
