Commins engine: 264/2200kW/rpm
The ZT-60/120AT Horizontal Directional Drilling (HDD) Rig represents a robust and reliable solution for modern trenchless technology applications. Designed with a conservative engineering philosophy, this rig prioritizes exceptional service life and operational stability. Critical components and the entire machine are built with a 10%-20% power reserve, ensuring reliable performance under peak loads and contributing to significantly reduced long-term operational costs.
Superior Drilling Power: Delivers a massive 30000 N.m of outer drill pipe torque and 4700 N.m of inner drill pipe torque, providing ample power for challenging ground conditions and large-diameter bores.
High Pullback and Thrust Capacity: A maximum pullback and thrust force of 1200 kN enables the handling of extensive product pipelines and complex, lengthy drills.
Powerful & Reliable Engine: Driven by a 264 kW / 2200 rpm Cummins diesel engine, ensuring consistent and dependable power output worldwide.
Optimized Drilling Functions: Features include rotary speed cruise control and an automatic swing function for inner drill pipes, enhancing operational ease and precision.
Flexible Drilling Range: With an entry angle adjustable from 8° to 20°, and compatibility with reamers from Φ300mm to Φ1000mm, the rig is versatile for various project specifications.
Integrated Support Systems: Equipped with a high-capacity mud pump (760 L/min at 10 MPa) for efficient spoil removal and bore stabilization, and an onboard 2-ton crane for handling drill pipes.
The ZT-60/120AT is built with a selection of internationally renowned components, guaranteeing high performance, durability, and minimal downtime.
Hydraulic System: Features a closed-loop hydraulic system for the rotation circuit. The main pumps for rotation, pullback, and thrust are Danfoss (Sauer-Danfoss) units (USA).
Hydraulic Motors: The rotation system is powered by 2 original Poclain motors (France), while the pullback and thrust system utilizes 2 Bombé hydraulic motors.
Fluid Conveyance & Control: The hydraulic system is fitted with high-pressure hoses from Semperit and Eaton (USA). Precision control is managed by Danfoss (USA) control valves.
High-Quality Hydraulic Fluid: Uses Shell hydraulic oil to ensure optimal lubrication, cooling, and system cleanliness.
