1. Long thrust cylinder stroke; only 3 round trips required per drill rod
2. High jacking force, retraction force, and clamping force
3. Fast jacking and retraction speeds for high construction efficiency
4. Dual engines; the number of engines in use can be determined based on pipe pulling conditions, saving fuel and improving economy
5. Intelligent control with constant jacking/retraction force, constant jacking/retraction speed, automatic engine idle, automatic fault detection and alarm, and other safety and high-speed construction functions
