- Main features of the drilling rig:
The HF series fully hydraulic core drilling rig is a new type of drilling rig developed by our company based on the advanced technologies of similar rigs both domestically and abroad. It is primarily designed for drilling in solid ore deposits, but can also be used for engineering geology exploration, shallow-depth oil and gas exploration, groundwater exploration, as well as for various engineering applications such as tunnel ventilation, drainage, and dam grouting. The drilling rig features full-hydraulic drive; its power head rotation is driven by an axial piston pump and a swashplate piston motor, with mechanical two-speed transmission and stepless speed regulation, boasting an advanced structural design. The power head employs a hydraulic cylinder-chain gear reduction mechanism for feed advancement, ensuring smooth and reliable operation. It is equipped with a lateral shifting mechanism for the power head, and the mast can be raised and lowered hydraulically, allowing it to slide entirely for overall movement. This enables drilling within a range of 45° to 90°. The hydraulic system adopts load-sensing control, delivering high efficiency and substantial torque. The rig is fitted with a hydraulic chuck for holding wooden logs, hydraulically adjustable leveling legs, and a telescopic mast, facilitating rapid positioning of the rig. It is also equipped with a wireless remote-controlled crawler track, making it suitable for a wide variety of terrains. Within a safe operating distance, the crawler track can be remotely controlled, effectively preventing sudden hazards.
