Product Description

Key Features:

1. The rig has an extensive speed range with 8 speed gears.
2. Low speed and high torque capabilities, suitable for both high-speed drilling and low-speed large diameter drilling.
3. Two reverse speed gears for easy and safe hole accident handling.
4. High installed power, with options for diesel engines or electric motors.
5. Advanced structure, reasonable layout, flexible operation, and easy maintenance.
6. Compact size, lightweight, and easy disassembly.
7. The feed stroke of the rig's spindle is up to 600mm, enhancing drilling efficiency and reducing drilling accidents.
8. Smooth movement, simple and reliable fixation, stable high-speed drilling, and a large distance from the hole.
9. The pressure gauge uses an oil-filled shockproof structure, with simple and accurate pressure value indication and a long service life.
10. The rig's chuck uses a hydraulic pin-style clamping system, ensuring a secure grip without damaging the active drill rod.
