Rig selection
Which drilling rig should I use for foundation piling?
It depends on hole diameter and depth. In our current range, 29 rig models have a published hole range for this work; the largest-capacity three are KG550 (hole 115β254 mm), KT20S (hole 135β254 mm), KT30 (hole 195β254 mm). Send us hole diameter, depth and rock type and we will confirm the fit.

Do I need an integrated rig or a separate compressor?
If the rig moves between benches weekly, an integrated machine reduces setup time. If you run several rigs on the same site, a centralised diesel compressor fleet costs less per hole and lets you size air to the hammer.
Can one rig handle both slope holes and production holes?
Yes β an integrated crawler with a wide hole range covers both. Tell us the slope angle and access width and we will confirm the carrier and mast.
Truck-mounted or crawler for a contracting business?
If your wells are spread over several hundred kilometres, truck-mounted pays for itself in mobilisation time. If you stay on one site for weeks in soft ground, a crawler drills more metres per shift.
Can a drilling rig be used for piling?
Yes, in rock the DTH method is often the fastest way to form a pile. Send the pile diameter, depth and geology and we will confirm the hammer class and air volume required.
How many piles per day can be expected?
On rock, output depends far more on relocation time than on drilling speed. Send us the array layout, pile spacing and geology and we will estimate a realistic daily rate.
Do I need a special machine for high altitude?
Yes. Tell us the working altitude and we will confirm the engine derating and the compressor class that still delivers the air volume your hammers need.
What should I order with the machine?
At minimum: hammer and bit set, service kit for the first interval, and high-wear consumables. We can prepare a spares list matched to your programme length.
What is different from normal water-well drilling?
Higher down-hole temperature and harder rock. We select hammers and seals rated for temperature and set the compressor class from the well depth and casing programme.
Can one compressor serve several geothermal rigs?
Yes, when the rigs work the same pad and the air line is short. Send us the programme and we will size the manifold and the hose run.
Which machines suit a small section?
Compact single-boom hydraulic jumbos. Send us the tunnel section and the hole pattern and we will confirm boom reach, feed length and tramming dimensions.
