Description

This is the JK930 chassis set up for buyers who spend their days in rock: quarry benches, mine access roads, foundation holes in limestone, geothermal boreholes through granite. Bigger hammer, higher air pressure, wider hole range, and a dust package fitted as standard for sites near villages or roads.

What changes against the water well version

  • Air package sized to the hammer you name, 17-35 m3/min at up to 2.5 MPa. Undersized air is why hammers bog down halfway down a hole
  • 138-350mm hole range, so blast holes and 300mm foundation holes come off the same mast
  • Cyclone collector with filter cartridges, or water injection at the collar, both knock down the visible plume
  • 300m capacity on 3m rods, handled on a hydraulic rack
  • 25t pullback and 8,000-10,000 N.m torque to free a loaded string in fractured ground

Penetration we see on customer sites

Clay, sand, gravel1.0-1.8 m per minute, mud rotary with tricone
Limestone, sandstone0.5-1.0 m per minute, 4 or 5 inch hammer
Granite, basalt0.2-0.5 m per minute, 5 or 6 inch hammer
Broken, weathered rock0.4-0.8 m per minute, 5 inch hammer with casing shoe

Bit condition, air setting and operator habits move those numbers by about 30 percent either way. If the bit is in rock from the first metre, order this configuration. If your ground is soil most of the way down, the water well version is cheaper and drills faster.

Send hole size, depth and rock type, and we confirm hammer, bit and compressor rating before the order is placed.
