Professional XW500 Crawler Drilling Rig with 30-150 RPM Speed for Geological Exploration

It's not a true dual-purpose rig for both water and steam drilling despite what some listings claim, so if you need that specific functionality you'll want to look elsewhere, but for straight geological exploration and water well work it handles the 500-600m depth range pretty well with the 138-325mm diameter bits.

The 118Kw Yuchai engine is actually a six-cylinder unit that's been reliable in other application we've seen, and the rotation torque sits between 13000-15000N.m depending on the gear setting — most buyers go with the higher end for harder formations, but you'll get better fuel economy at teh lower range if your ground is softer.

Power head travel at 6.6m means you're not constantly stopping to add pipe, which is the main bottleneck on these rigs, and the 30-150 RPM speed range gives you enough flexibility to match different rock types without swapping gearboxes, though the climbing ability is capped at 30° so steep hillsides can be tricky.

Air consumption runs 18-42m³/min at 1.7-3.5MPa working presure, so you'll need a decent compressor setup (usually 2-4 weeks lead time on that separately), and the drill pipe options are 76, 89, 102, or 114mm depending on your casing preference.

Lead time is roughly 45-60 days from order, and we usually have stock on hydraulic crawler units but confirm before ordering, bulk pricing kicks in around 3 units or so with about 8-12% off the single-unit price.

Weight is 10T with dimnesions of 4150×1900×2480mm, so transport isn't too bad, and the warranty is one year with online support — not ideal if you need onsite technicians, but for the price point it's better than most in this class.
