Customizable 100-200m Depth DTH Drilling Rig with 7-15km/h Walking Speed for Mining Projects

We've seen these rigs handle everything form iron ore test holes to small-scale quarry work, and the 30HP engine with 1800N.m torque is plenty for most medium hard rock (F=8-12) — just don't expect it to chew through granite all day. The walking speed of 7-15km/h on those crawlers means you can reposition between holes in a few minutes, which is pretty much essential on a big grid pattern. We usually have the 1.2t unit in stock with the diamond bit option, but confirm lead time if you need the AC motor variant.

Borehole depth runs 100-200m depending on your air supply, and at 6m³/min consumption you'll want a decent compressor on site — we don't include that, so factor it into your setup. The single pump hydraulic system at 20Mpa keeps things simple for maintenance, but it's not as fast as a dual-pump for simultaneous functions. Most buyers go with teh 50-300mm diameter range for exploration work, but we've had guys push it to 350mm with a custom bit (check with us first).

The 6.6m power head stroke means fewer rod changes than shorter-stroke rigs, and that 2.8m carriage travel gives you flexibility on uneven ground. It climbs 35° slopes without much drama — we've tested it on a muddy hillside in the wet season, and the four hydraulic legs kept it stable. One thing that catches some buyers: the hydraulic cooler works fine for continuous operation, but if you're drilling in 40°C ambient for hours, you might need an auxiliary fan kit (our company can quote that).

Qualiy-wise, every unit ships with a COA and the hydraulics are tested at 20Mpa before dispatch — we've had maybe 2% warranty claims over a year, mostly on the crawler gearbox seals. The 1-year parts but not labor, and we usually have spares in stock for the rotary head and pump. For ordering, MOQ is 1 unit, lead time is roughly 20 days or so for standdard config, but if you want the diamond bit included, add 5 working days.

Anyway, it's better than a lot of the Chinese rigs we've seen for this price range — the 30-150 rpm rotation speed gives you good control in variable rock, and the rotary/DTH method switch is straightforward. Not suited for deep geothermal or hard quartzite (F>14), but for mining projects with medium hard rock, it's a solid workhorse. We usually suggest buyers budget for spare hydraulic hoses and a set of seals, because those are the first things to go on site.
