- Compact structure, small volume and light weight with quick disassembly capability for easy handling in mountainous and hilly terrain
- Dual-cylinder hydraulic feed system provides fast drilling speed and high working efficiency compared to similar products
- Operation panel with pressure gauge for real-time monitoring of downhole conditions, allowing adjustments based on terrain variations
- 4-speed shifting system enables operators to freely adjust rotation speed according to geological conditions, with slow reverse gear for easy drill rod disassembly
This small sampling drilling equipment is ideal for plains, mountainous areas, and locations with limited transportation and energy access. With its compact structure, small footprint, light weight, and easy mobility, it is perfectly suited for geological sampling surveys, geological core collection, small grouting holes, and blasting holes in railway, water conservancy, and other construction projects across various outdoor environments.
