ZT-400 Maxi Rig HDD Machine

The ZT-400 maxi rig hdd machine is a professional heavy-duty horizontal directional drilling solution engineered for complex underground construction projects. Its power source and core hydraulic components adopt foreign advanced technologies, ensuring exceptional reliability and robust power output.

The machine supports single-unit engine startup for guiding and other precision construction processes, enhancing operational flexibility and energy efficiency. Equipped with an 11-inch imported AI touch LCD screen, it achieves energy conservation and emission reduction, simplifies operation, and enables intelligent data storage. The independent cab design further guarantees a comfortable working environment for operators, improving work efficiency during long-hour construction.

Core Product Features

• Rotary Feed Double Closed System: Adopts a rotary feed double closed-loop control system, which ensures stable operation and high drilling efficiency. This system minimizes operational fluctuations, enhances drilling precision, and is suitable for high-standard construction scenarios requiring consistent performance.
• Integrated Gripper Movement Design: The gripper features overall movement functionality, facilitating quick and convenient shackle operations. The upper gripper design optimizes the overall movement stroke, reducing the number of operational steps and improving construction efficiency while lowering operator labor intensity.
• Imported High-Quality Quick Connector: Equipped with foreign imported brand quick connectors, boasting reliable sealing performance. This design effectively prevents hydraulic oil leakage, ensures the stable operation of the hydraulic system, and reduces maintenance costs and downtime.
