DTH Hammer Crawler Water Well Drilling Rig 500m 4.5MPa High Pressure Borehole JKS500C

The JKS500C DTH hammer crawler water well drilling rig is a high-pressure machine designed for one purpose: fast penetration in hard rock. Working with a 1.05-4.5MPa air supply and 16-60m³/min air consumption, the DTH hammer strikes directly on the bit, so impact energy is not lost through long drill rods. This delivers penetration rates several times faster than conventional rotary drilling in granite, basalt and limestone. The rig accepts drill pipe diameters of 89mm, 102mm and 114mm, and its 25T lifting force handles deep 500m strings with ease. The 9500N.m rotary head provides the smooth, controlled rotation DTH drilling demands.

• High-pressure DTH: 1.05-4.5MPa working pressure drives powerful down-the-hole hammers for hard rock drilling.
• 25T lifting capacity: pulls long drill strings and stuck tools with confidence in deep boreholes.
• Multiple pipe sizes: accepts 89mm, 102mm and 114mm drill pipes for flexible tool string design.
• Efficient air flushing: 16-60m³/min air flow cleans the hole continuously, reducing stuck-pipe risk.
• Balanced axial control: ±10T axial pressure keeps the hammer seated on the rock for maximum impact transfer.
• Heavy-duty tracks: reinforced crawler chassis and 13T weight provide a stable platform for high-frequency hammering.

The JKS500C is the rig of choice for deep community water wells in hard rock regions, livestock supply bores, mining camp water supplies and geothermal exploration. Its high-pressure DTH capability also suits gas drainage, blasthole drilling in quarries and trenchless crossing pilot holes where straight, fast holes in competent rock are the priority.

The JKS500C is exported with steel-frame crating, weatherproof wrapping and oiled protection on all machined surfaces. Before shipment the air circuit, hydraulic system and rotation head are tested under load. The package includes a one-year warranty, complete manuals, spare parts kit and remote technical support for rig assembly, commissioning and relocation.
