Backhoe loaders are versatile construction machines widely used across Australian civil, utility, and construction sites for trenching, excavation, material handling, and concrete breaking. When fitted with a hydraulic rock breaker or excavator hammer attachment, backhoe loaders become highly effective tools for asphalt removal, pipe bedding preparation, utility trenching, and light to medium demolition work. DOZCO supplies hydraulic breakers for backhoe loaders across Australia, with models specifically designed to match the hydraulic capacity of backhoe loader circuits. Our Light Plus Range (100A, 200A, 300A) and Light Range (370A, 430A, D75, 450A) hydraulic hammers are compatible with the majority of standard backhoe loaders operating in Melbourne, Sydney, Perth, Brisbane, and regional Australian job sites.
Whether you operate a Caterpillar backhoe, JCB 4CX, Case backhoe loader, or Komatsu backhoe for roadworks, utility projects, or light construction, DOZCO has a hydraulic excavator breaker built to fit your machine and perform reliably under Australian conditions
