The entire machine excels in all parameters: high rotation speed, large torque, fast push-pull speed, excellent controllability, energy-saving and efficient performance, as well as intelligent and user-friendly operation. The rig’s rotation and push-pull hydraulic systems adopt closed-loop design, delivering high energy efficiency. The electronic control system uses imported Danfoss controllers and Murphy displays for simple and comfortable human-machine interaction. It employs CAN bus technology for high control precision and fast response. The rig features torque limiting function for making up connections, and automatic adaptation of rotation and push-pull to working conditions, reducing construction difficulty while achieving scientific and efficient performance.

Key Features:

Equipped with three Cummins electronically injected engines, delivering strong and powerful performance. Any single engine can be used independently, saving energy consumption and adapting to different working conditions.

Closed-loop system for rotation and push-pull, with high system efficiency. The piping is equipped with high-pressure filters to block contaminants between the pump and motor, effectively protecting the pump and motor.

Separate cab from the main machine, with convenient connection, comfortable operation, and equipped with Murphy 11-inch large-screen display, offering a friendly human-machine interface and high level of intelligence.

Danfoss crawler walking system adopts wireless remote control, with high reliability and excellent performance. Under constant torque conditions, during reaming in rock formations, when rotation pressure is constant, pull-back and rotation operate simultaneously. When rotation pressure increases, pull-back automatically stops to prevent stuck drill rods.

Speed-increasing transfer case increases the input speed of the oil pump, improving output flow and output power.

Preset pressure system for rotation and push-pull, allowing pre-setting of system parameters according to drill tool requirements, enhancing construction safety.
