280T Smart Operating Cabin With Real-time Monitoring Horizontal Directional

Product Specification

280T Smart Operating Cabin With Real-time Monitoring Horizontal Directional Drilling Rig

Product Overview:

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. 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%. Auto-centering clamping rotary gripper with 70,000 Nm make-up torque and 140,000 Nm breakout torque ,accelerating rod changes by 40 seconds . Onboard crane,  smart operating cabin with real-time monitoring of over ten data points.      while the dual-control (wireline +manual) emergency walking system, combined with an expansive operational field of view, , safety and operational efficiency are prioritized.
