Advantages
Core Mechanical Advantages
Powerful Engine: Equipped with Cummins Diesel Engine QSL8.9-C360-30 (264kw/2200rpm) and a growth speed transfer case, which enhances oil pump input speed, improves output flow and transmission power, while optimizing fuel economy.
Top-Tier Hydraulic System: 4 Sauer-Danfoss oil pumps (for rotation, thrusting/pulling, and mud pump control) + Danfoss/BONDIOLI hydraulic motors + French Poclain motors (external drill rod rotation) + US Eaton motors (internal drill rod rotation), ensuring reliable performance and high efficiency.
Exceptional Drilling Capability: External drill rod (OD102mm×4m) with 35000Nm torque & 0-170 r.p.m spindle speed; internal drill rod (OD60mm×4m) with 4700Nm torque & 0-180 r.p.m spindle speed. Max thrust/pullback force reaches 1500KN, handling tough drilling demands with ease.
Advanced Technical Features
Closed-Loop Hydraulic & Load Sensing Control: The horizontal directional drilling equipment adopts a closed-loop hydraulic system for the rotary system and load sensing control, improving overall efficiency by 15% compared to conventional systems.
Three-Speed Design for External Drill Rod: Avoids the dilemma of high torque with low speed and high speed with low torque, significantly boosting construction efficiency, especially in rock drilling scenarios.
Semi-Automatic Operation: Equipped with a semi-automatic rod loader system, hydraulic clamp for drill rod makeup/breakout, and threads grease feeding system, reducing manual intervention and operational fatigue.
User-Centric Design & Reliability
Ergonomic Cabin: Electric rotating seat with AC, modern control panel, and DSE screen monitor, providing a comfortable and intuitive operating experience.
Robust Structure: Two-point four-bar linkage frame (entry angle: 14-23°), 800L ceramic-cylinder mud pump (800L/min@9Mpa), 3.2T crane, and washing gun, adapting to diverse construction environments.
Long Service Life: Conservative design with 10%-20% power reserve for key components, paired with imported parts (Sempe/Eaton hydraulic oil pipes, Shell hydraulic oil, Danfoss control valves) for extended durability.
Top-Tier Components: All hydraulic parts are international leading brands, ensuring reliable performance and low maintenance costs.
High Efficiency: Closed-loop hydraulic system + three-speed design + semi-automatic operation, improving construction efficiency by 15%+.
Strong Adaptability: 14-23° entry angle, 24T weight, and compact dimensions, suitable for urban, rural, and complex geological trenchless projects.
Intelligent Operation: Fixed speed cruise for rotary, internal drill pipe automatic remote swing, and electric rotating seat, reducing operator fatigue.
