ZR77

High-impact productivity with precision control

Designed for consistent performance in tough conditions, the ZR77 is equipped with a robust boxer-style mast and a high-force rack-and-pinion pulldown system. These features combine to maximize torque delivery and bit load, enabling faster cycle times and increased drilling efficiency.

• High-force rack-and-pinion pulldown: Enables faster cycle times and increased penetration in hard rock; boosts drilling time by up to 12%.
• Automated bit carousel: Minimizes downtime with quick, hands-free bit change-outs; helps maintain efficient fragmentation and hole quality.
• Boxer-style mast design: Enhances structural durability for improved availability and reduced maintenance overhead.
• Optional remote operation: Helps limit operator exposure and aligns with zero harm initiatives.
