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