HEPI Enhancements

Solutions

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.
