We design and build our trailer mounted water well drilling rig series for contractors who can't afford to choose between speed and drilling power. Every trailer-mounted water well drill we manufacture runs on a full-hydraulic system and switches between air, mud, and foam rotary drilling on the same machine — so you're never stuck with the wrong method halfway through a job. From our compact, single-operator portable trailer water well drilling rig models up through our deepest-rated platforms, we've engineered this series to get to site fast, set up in minutes, and keep drilling where wheel-less machines can't follow.

If you're comparing options, our full lineup of trailer mounted water well drilling rigs for sale covers depths from 110m to 400m — we'll help you match the right model to your project below.

Why We Build Every Rig on a Trailer Chassis

We chose the trailer configuration for a reason: it's the fastest way to get a full-power drilling rig into places a truck or crawler can't easily reach. A trailer mounted water well drilling rig tows behind a standard pickup, threads through narrow rural access roads, and sets up on hillside or village sites without requiring a dedicated heavy-vehicle driver. On rural water supply, irrigation, and geothermal projects — where site access, not raw horsepower, is usually the bottleneck — that mobility is what gets you drilling on schedule.

Every hydraulic trailer water well drilling rig in our lineup uses full-hydraulic control for the mast, leveling legs, rotary head, and feed system. That means faster setup, a shorter learning curve for new operators, and fewer mechanical failure points than mechanical or semi-hydraulic alternatives. We also build every model with dual-method drilling capability: run it as a trailer mounted DTH water well drilling rig for hard rock formations using air hammer drilling, then switch to mud or foam rotary the moment you hit soft sediment — without changing machines.

How to Choose the Right Model for Your Project

We get asked the same three questions from nearly every buyer, so here's how we'd walk you through it:

● What's your target depth and hole diameter? Our range runs from 110m (TWD100) to 400m (TWD400/TWD400B), with hole diameters from 90mm up to 450mm. We always recommend sizing to your deepest anticipated well, not your average one — undersized torque or mast stroke is the single most common mistake we see buyers make.

● What formations are you drilling through? If your sites mix hard rock with unconsolidated ground, we'd steer you toward a higher-torque model with strong DTH hammer compatibility. If you're mostly in soft ground, mud/foam rotary performance and pump capacity matter more to you than raw torque.

● What's your tow vehicle and site access like? Our lighter models (TWD100–TWD200) tow behind a standard pickup and fit tight rural roads; TWD300 and above need a properly rated tow von the same jobsite where our trailer rig can't fit, and where casing/foundation work calls for stationary drilling power.

● Truck-mounted rigs trade some of that mobility for higher horsepower and faster road transport between distant sites — a better fit if you're covering large territory with fewer, deeper wells.

● Trailer-mounted rigs, our specialty, sit in between: full drilling power, but light enough to reach the sites the other two configurations struggle with.

If you're not sure which configuration — or which model within our trailer series — fits your project, send us your target depth and formation data and we'll recommend a specific rig, free of charge.

Ready to Ship, Wherever You're Drilling

We export our trailer mounted water well drilling rigs to more than 40 countries, and we build our shipping process around that. Every rig can be shipped fully assembled or broken down and crated for standard container loading, depending on your port and inland transport constraints. Our regional service agents across Africa, Latin America, and Southeast Asia mean that when your rig arrives, technical support and spare parts aren't a transoceanic phone call away.

Frequently Asked Questions

What depth can a trailer mounted water well drilling rig reach?
Across our series, depth capacity ranges from 110m on the compact TWD100 up to 400m on the TWD400B, depending on formation type and hole diameter.

Can the same rig drill both soft soil and hard rock?
Yes — every model we build supports both mud/foam rotary drilling for soft formations and air DTH hammer drilling for hard rock, switchable on the same rig without changing machines.

What tow vehicle do I need?
Our lighter models (TWD100–TWD200) can be towed with a standard pickup truck; TWD300 and above need a heavier-duty tow vehicle rated for the trailer's loaded weight. Tell us your model of interest and we'll confirm the requirement.

Do you supply the air compressor for DTH hammer drilling?
Yes. As an authorized partner for major air compressor brands, we configure and supply a matched compressor sized to your drilling diameter and depth target.

Can you ship the rig disassembled for easier logistics?
Yes — every model in this series can be shipped fully assembled or broken down and palletized/crated, depending on your port and inland transport situation.
