ZT-100/150A Heavy-Duty Horizontal Directional Drill (HDD Rig) | Drillto

The ZT-100/150A Heavy-Duty Horizontal Directional Drill (HDD Rig) is a heavy-duty horizontal directional drilling machine engineered for large-scale underground construction (e.g., pipeline installation, utility trenching). With industry-leading torque, pull force, and intelligent controls, it delivers reliable performance for complex drilling projects while minimizing operational costs.

Core Features & Advantages

1. Powerful & Efficient Engine

   Equipped with a 264kw Dongfeng Cummins electric injection diesel engine, the ZT-100/150A Heavy-Duty Horizontal Directional Drill offers strong power, low noise, and reduced fuel consumption – critical for long-duration drilling projects.
2. Industry-Leading Performance Metrics

   With 45000 N.m max torque, 1500KN pull/thrust force, and 50m/min pulling speed, it handles tough formations (e.g., rock, compacted soil) with fast, precise operation.
3. Top-Tier Hydraulic & Rotary Systems
   • Hydraulic parts from international premium brands ensure reliability and efficiency.
   • Closed rotary system + load-sensitive push-pull system (volume speed regulation) = high transmission efficiency, low heat generation, and energy savings.
   • Low-speed, high-torque rotary motor (dual-motor three-speed design, patent-protected dynamic switching) enables on-the-fly gear adjustment to boost construction efficiency.
4. Advanced Safety & Control Systems
   • Anti-rebound system for push/pull operations (prevents hydraulic component damage).
   • Constant torque control (patented) for scientific reaming via preset torque values.
   • Swing drilling function expands adaptability to formations with direction-change challenges.
   • Shock-overload protection + active oil replenishment system reduce failure rates.
5. User-Friendly & Intelligent Operation
   • German Jesman multi-function handle: One-hand control of grippers/feed/rotation; one-key shackle.
   • Cruise control (restores last settings with one key) for streamlined operation.
   • Danfoss CAN bus control system (7-inch display): Fast response, comprehensive host parameters, and a user-friendly interface.
6. Practical Design Enhancements
• Rotatable cabin (excellent visibility) + 3.2-ton crane (easy drill pipe loading/unloading).
• Patented drill rod thread protection system (self-floating box mechanism) reduces thread wear and extends component lifespan.
