Product Description
Key Features
Measuring the underground with technology, safeguarding the future with craftsmanship.
This HDD machine is equipped with a National Stage III-compliant 390kW Weichai turbocharged common rail diesel engine, delivering 530 horsepower. It maintains stable performance in extreme conditions ranging from -40°C to 50°C. The hydraulic system employs a closed + open dual-circuit intelligent load distribution system, ensuring optimal performance for propulsion, retraction, and rotation in complex conditions.
All-in-One Intelligence. Redefining HDD Efficiency.
THD-280 HDD Rig integrates a onboard crane, a dual-person smart operating cabin with real-time monitoring of over ten data points. The "holographic monitoring" system provides intelligent protection, while the dual-control (wireline +manual) emergency walking system, combined with an expansive operational field of view, , safety and operational efficiency are prioritized.
Massive Torque, Single-Pass Efficiency.
Thrust and Pullback system features a 280-ton 6- stage gear -rack drive with a 3 step-less adjustable transmission ,effortlessly navigating complex terrains. Its tracked chassis conquers 30° slopes with ease.. The rotation system delivers 60,000 Nm ultra-high torque and a 25,000 Nm rapid retraction mode, enabling "single-pass drilling" efficiency ,which reduces construction duration by over 30%.
