Product Applications
The JRC500 Crawler hydraulic RC core drilling machine is a versatile and high-efficiency equipment designed for soil testing and geological investigations. It utilizes advanced foreign gas lift reverse circulation drilling technology, which allows efficient collection of rock dust through a dust collector, reducing environmental pollution. This system is ideal for geological prospecting departments that require sampling and analysis. The rig is suitable for various applications such as geological exploration, well drilling, monitoring wells, and ground source heat pump systems. It can also be used for compressed air reverse circulation drilling on the surface, significantly improving construction efficiency and quality by integrating multiple hydraulic systems.
Product Description
1. Equipped with a diesel engine-driven hydraulic system, all operations including walking, rotation, feeding, lifting, leg adjustment, compensation, and rod change are hydraulically controlled.
2. Combines reverse circulation with DTH (Down-The-Hole) technology, utilizing an air compressor for impact and dust collection.
3. During operation, a reverse circulation hammer and double-tube system are used, where compressed air enters between the tubes and dust exits through the inner tube.
4. Also supports positive circulation drilling using standard drilling tools.
5. The working system includes feed system, guide (mast), rotary head, compensation system, centralizer, rod exchange system, and winch.
6. Adjustable pressure, feed speed, and rotational speed for optimal performance.
7. Self-walking system with four hydraulic legs, allowing easy transport without the need for lifting when loading onto a truck.
8. Four hydraulic legs ensure stability during drilling operations.
9. The sub-winch can lift up to 1 ton of drilling tools and assist in rod changes.
10. The guide (mast) operates within a range of 45° to 90°, featuring an extension system to maintain balance during drilling.
