HEPI Enhanced offerings are built on the decades-long legacy of Birrana engineering—renowned for advancing the performance, reliability, and longevity of heavy equipment. Today, that heritage of innovation continues through proprietary processes and purpose-designed components that extend service life and maximize machine availability. From advanced planetary and brake redesigns to underground drive axles, gearing, and suspension systems, every HEPI enhancement reflects a commitment to smarter design and lasting value. Purpose-engineered tools such as HEPI oil sample plugs, brake wear gauges, and collated pins further demonstrate how innovation, grounded in proven engineering, keeps operations running longer, safer, and more efficiently.
Born from a legacy of Birrana engineering enhancements in South Australia, Our HEPI Enhanced Final Drives integrate advanced features like Contamination Guards, Carbon Friction Discs, Flexible Spacers, and more—engineered to maximize reliability, extend component life, and reduce total cost of ownership.
