JKS300B — 300 m crawler
The contractor workhorse. Combined mud and DTH capability in a compact crawler frame, sized for regional water well programmes.
There is no single price for a drilling rig, and any supplier who quotes one number before asking about your ground is guessing. Six variables move the figure — depth rating, hole diameter, mounting, engine, air package and certification. This guide explains how each one shifts the number, so you can read any quotation, ours or a competitor's, and see where the money actually goes.
Two rigs rated for the same depth can differ by a third of the price. The gap is rarely the steel — it is the power train, the pump package and the certification. A 300 m crawler with a Yuchai engine and a BW250 mud pump is a different machine from the same 300 m crawler with a Cummins engine, a BW320 pump and an air package for DTH hammer work. Both are honest 300 m rigs. They are built for different ground.
That is why every serious quotation starts with four questions: how deep, what diameter, what formation, and where will it work. Answer those and the band narrows fast. Skip them and you will be comparing three machines that were never the same class to begin with.
Ordered by how much they typically shift the final figure.
Four product lines cover most enquiries. Each has its own cost driver, so comparing a water well rig with an HDD rig on price alone tells you nothing useful.
| Rig type | Typical specification | What moves the price most | Where it is used |
|---|---|---|---|
| Water well drilling rigs | 100–600 m depth, 100–400 mm hole | Depth rating, then mounting | Domestic, irrigation and municipal wells |
| Horizontal directional drilling rigs | 20–500 t pullback | Pullback force and torque | Utility, road, river and rail crossings |
| Geological core rigs | 300–2,000 m capacity | Depth capacity and wireline capability | Mineral exploration, geotechnical survey |
| Workover rigs | 30–150 t | Tonnage and carrier type | Oilfield well service and completion |
Indicative positioning only — every model is configured to order, so the final figure follows your specification rather than the nameplate.
The contractor workhorse. Combined mud and DTH capability in a compact crawler frame, sized for regional water well programmes.
Deep-well class with a telescoping mast that cuts rod-trip time. Built for contractors running continuous deep holes.
Mid-range directional drilling unit for utility and road crossings, with the mud system sized to match the rod string.
Larger pullback for municipal gas, water and sewer work where bore length and soil pressure both climb.
Track-mounted underground deep-hole rig for development drifts, where frame size decides whether the machine fits at all.
Conventional land rig for shallow development and workover support, configured to the client's casing programme.
Water well, HDD, core and workover rigs cover most enquiries, but four more categories come up regularly — and they are priced on different logic. A solar pile driver carries a lighter mast and a different hammer, so it sits well below a water well rig of the same reach. An anchor drilling rig for slope and foundation work belongs in the small-machine band, where mobility matters more than depth. A geotechnical drilling rig is normally a compact, low-impact unit for site investigation, often trailer- or track-mounted. And an RC drilling rig costs more than a comparable core rig because the sample recovery system is the expensive part, not the mast.
Tooling is a separate line. Drill rods, bits, mud pumps and reamers are usually budgeted alongside the machine rather than inside it, and on HDD work the tooling package typically runs 15–25% of the rig budget. If you are weighing used against new, read the note on used drilling rig sale pricing below before you commit — the headline saving rarely survives the first repair.
Ask for the quotation split into four lines: rig, tooling, freight and certification. A single lump sum hides which line was cut to reach the number — and it is almost always the pump, the compressor or the certification, which are the three most expensive things to add later.
The four questions that come up in almost every price enquiry.
It depends on the class and the configuration, not on a catalogue. Depth rating moves the figure most — stepping from a 200 m class to a 400 m class typically adds 40–60%. Mounting, engine brand, air package and certification then swing the rest. Tell us your depth, hole diameter and formation, and we will confirm the band for your specification within 24 hours.
Because a fixed list would be wrong for almost everyone. The same 300 m chassis is sold with three engine options, two pump sizes and with or without an air package — those choices change the figure materially. A published number would either be the cheapest possible build (and mislead you) or the most expensive (and lose the order). We quote against your ground instead.
The headline price is lower; the five-year cost often is not. Used machines usually arrive without warranty, with unknown hours on the hydraulic system, and with a parts spec that may already be discontinued. If you are comparing, ask for the hour meter, the last hydraulic oil analysis and the availability of a pump seal kit — those three answers separate a bargain from a project.
Yes, all three. FOB from Qingdao or Tianjin is the default for buyers with their own freight forwarder. CIF suits first-time importers who want one number to their port. DAP is available where inland delivery is straightforward. Send your nearest port through the contact page and we will price all three for comparison.
Depth, hole diameter, formation and destination port — four lines of information is enough for our engineers to size the rig and return a price range within one working day.
