Developed in close collaboration with Australian underground mining operations, HBT’s mobile bolters are engineered to reduce operator fatigue and deliver exceptional performance. From the streamlined platform layout to the intuitive control interface, our engineers have designed an ergonomic machine that performs efficiently in confined spaces and under the harshest conditions.
The HBT Warabolter is purpose-built for demanding local environments and features fast, dependable Waratah bolting modules. Capable of installing up to six bolts simultaneously, the Warabolter is available in two chassis sizes and offers a range of configurable options. With its operator-focused design and robust construction, it ensures consistent productivity across even the toughest Australian mine sites.
Designed and manufactured in Australia, the Warabolter meets the highest industry standards. Its ergonomic layout, operator safety features, and customizable components make it a reliable solution for continuous operations in challenging underground mining conditions.
The Warabolter incorporates field-proven Waratah roof and rib bolters, equipped with automated control for drilling and positioning, including auto water on/off and mast extend/retract functions during the drilling cycle. Multiple bolter sizes are available to support single-pass bolting. Waratah Engineering can further tailor configurations to meet the unique requirements of specific mining domains.
Designed with extensive input from the Australian underground mining workforce, the Warabolter focuses on minimizing fatigue and maximizing ease-of-use. The well-organized cabin and intuitive controls allow operators to safely and efficiently maneuver the machine in confined headings, making it a favorite at the coal face.
The Warabolter’s chassis is built from high-strength Bisalloy steel, offering a yield strength three times higher than standard carbon steel. Robust engineering choices include reinforced and widened platforms with rib protection, durable crawler frames, and upgraded planetary traction drives—ensuring reliability in even the harshest mining environments.
Designed for uninterrupted operation, the Warabolter features a spacious, easily accessible storage pod for bolting consumables. This minimizes downtime and supports continuous productivity. The Bolting Pod is customizable to suit specific operational needs.
The built-in Mesh Handler allows for quick, precise, and safe positioning of wire mesh panels. This streamlines the ground support process while reducing physical strain and operator fatigue. Like other features, the mesh handler can be tailored to individual site requirements.
Power delivery is managed via a high-performance hydraulic-driven cable reel system with constant tension control and an integrated cable minder. This setup ensures smooth operation, improved cable lifespan, and reduced risk of cable damage.
