YDX-200 Crawler Hydraulic Core Drilling Rig

Product Overview

The YDX-200 crawler hydraulic core drilling rig is a compact, high-efficiency geological exploration rig engineered for wireline diamond coring, mineral prospecting, and geotechnical engineering surveys up to 200 meters deep. Powered by a 56 kW diesel engine and a high-torque rotary top-drive system delivering 900 N·m torque at up to 1,100 rpm, this crawler core drilling rig achieves high core recovery rates in complex rock formations using thin-walled diamond bits (BTW, NTW, HTW). Equipped with an integrated Auto SPT (Standard Penetration Test) hammer system and mast ground-touching hydraulic outriggers, the rig supports adjustable angle drilling from 45 ∘ 45 ∘ to 90 ∘ 90 ∘ with optimal stability. Its self-propelled rubber crawler undercarriage enables agile all-terrain mobility and rapid jobsite positioning.

Product Features

Integrated Automatic SPT System: Built-in automated Standard Penetration Test mechanism featuring a standard 63.5 kg drop hammer, 76 cm stroke, and a continuous drop frequency of 30–50 blows per minute for accurate in-situ geotechnical soil testing.
$4 5^{\circ} - 9 0^{\circ}$ Multi-Angle Drilling Capability: The heavy-duty drill mast swivels continuously between $4 5^{\circ}$ inclined and $9 0^{\circ}$ vertical positions, backed by ground-contact structural mast supports to eliminate vibration during high-speed diamond drilling.
High-Torque & High-Speed Hydraulic Top-Drive: Delivers continuous stepless speed regulation from low-speed high-torque casing operations up to 1,100 rpm for diamond wireline coring with 8-ton (80 kN) pullback capacity.
High-Mobility Rubber Crawler Undercarriage: Self-propelled rubber tracks deliver a travel speed of 2.5 km/h and climbing capability up to $3 5^{\circ}$ gradient, providing low ground-bearing pressure and zero damage to paved access roads.
Compact Footprint & Rigid Frame: Measures only $3, 500 \times 1, 500 \times 1, 800 mm$ in transport configuration, enabling rapid mobilization in narrow mountain trails, forested tracks, and confined urban geotechnical sites.

Applications

Mineral Prospecting & Diamond Core Drilling: Wireline core sampling of metallic and non-metallic mineral deposits up to 200 meters deep.
Geotechnical Site Investigation & Soil Testing: Conducting Standard Penetration Tests (Auto SPT), foundation bearing capacity testing, and borehole logging for civil engineering structures.
Hydrogeological & Environmental Exploration: Drilling shallow groundwater monitoring wells and conducting geo-environmental soil and water quality sampling.
Infrastructure & Dam Grouting: Vertical and inclined borehole drilling for tunnel anchor reinforcement, landslide stabilization, and dam curtain grouting.

FAQ

Q1: What drilling diameter standards are compatible with the YDX-200 rig?

A: The YDX-200 is engineered for standard wireline diamond core drilling systems, fully supporting BTW, NTW, and HTW rod and core barrel specifications. The high top-drive spindle speed (up to 1,100 rpm) pairs seamlessly with thin-wall impregnated diamond core bits to maximize daily core penetration rates.

Q2: How does the integrated Auto SPT mechanism work during geotechnical site surveys?

A: The integrated Auto SPT module features an automated trip-release mechanism that lifts and drops a standard 63.5 kg hammer from a precise 76 cm drop height at a rate of 30–50 impacts per minute. This eliminates human error associated with manual rope-and-cathead methods, ensuring standardized geotechnical N-value data compliance.

Q3: Can the YDX-200 drill angle holes on mountainous or uneven terrain?

A: Yes. The mast can be hydraulically inclined and locked securely at any angle between $45^{\circ}$ 45∘ and $90^{\circ}$ 90∘. Additionally, the mast features hydraulic ground-touching jack supports that plant directly against the soil, which works together with the hydraulic leveling outriggers to maintain stability on uneven ground.
