The Benefits of the HZR400
Balanced Power for Mid-Scale Projects
The HZR400 offers the ideal balance between torque, feed force, and compact design—fitting a wide range of applications. It’s engineered for jobs where the diameter requirements go beyond smaller rigs but don’t yet call for the size of the HZR610 or 1200. Its modular frame allows jobsite adaptation, making it both versatile and transport-friendly.
Dependable Performance in Mixed Ground
From fill materials to boulder fields and fractured rock, the HZR400 maintains steady progress with minimal operator intervention. Its rotation and feed systems are optimized for stability, and casing advancement remains smooth even in inconsistent layers. Contractors across Europe and North America rely on it for consistent project outcomes.
Power Pack Options for HZR400
The HZR400 is paired with the Geonex PP100 power pack, a compact yet powerful hydraulic unit designed specifically for this rig. It includes an integrated air compressor and supports radio control, enabling safe and efficient operation from a distance. The PP100 delivers the necessary torque and feed pressure for challenging bores, while its streamlined design simplifies transport and setup—ideal for contractors who value reliability and flexibility in mid-size trenchless projects.
Wide range of drilling equipment
Geonex offers a complete selection of drilling tools to match the full range of casing diameters supported by the HZR220. From pilot bits and ring bits to augers and DTH hammers, every component is designed to integrate seamlessly with the rig and power pack. Tooling can be easily adapted on-site to meet project-specific requirements, helping crews respond quickly to varying conditions. All equipment is built for durability, fast handling, and precise operation—giving contractors the flexibility to take on a wide variety of bore profiles with confidence.
