Drilling Equipment
Reliable rigs for mineral exploration, water wells & geotechnical drilling
YG Machinery offers a comprehensive Drilling Equipment portfolio that covers every stage of subsurface investigation — from deep mineral exploration to shallow water well drilling. Whether you require a high‑powered fully hydraulic core rig, a versatile vertical spindle drill for dual‑purpose projects, or a lightweight portable borehole machine for remote sites, our engineering focuses on efficiency, durability, and low total cost of ownership. Backed by global technical support and cross‑border after‑sales service, YG’s drilling solutions are trusted by exploration teams, water well contractors, and geotechnical engineers worldwide.
⚙️ Fully Hydraulic Core Drilling Rig – YGX Series
Designed for deep mineral exploration and complex formations, the YGX series fully hydraulic core drilling rigs represent the mainstream development direction in geological exploration. The lineup includes four models: YGX‑400, YGX‑600, YGX‑800, and YGX‑1000, covering drilling depths from 180 meters up to 1100 meters (NQ). Powered by reliable Yuchai or Cummins engines (78kW to 154kW), the rigs integrate a dual cooling system (air‑cooling + water‑cooling) that prevents overheating during high‑intensity cycles, significantly extending hydraulic component life.
Using closed‑loop hydraulic control, the YGX series achieves infinitely variable speed adjustment, multi‑angle drilling from 0° to 90°, and outstanding lifting forces (up to 30 tons on the YGX‑1000). Rated flow ranges from 168 to 300 L/min, ensuring stable rotary torque and fast penetration rates. The rigs support wireline coring, deliver high core recovery, and are built with a heavy‑duty steel structure for vibration absorption. Whether for solid mineral prospecting or deep geotechnical surveys, these full hydraulic core drills combine automation, low maintenance costs, and high efficiency. YG also provides cross‑border after‑sales support, including online/video guidance and on‑site technician dispatch.
🔩 Core Drill Rig For Sale – Vertical Spindle Series
For shallow to medium‑depth projects (200 meters) that require both mineral exploration and camp water well drilling, the vertical spindle core drill rig offers an exceptionally cost‑effective and flexible solution. YG’s 100‑meter series (YG‑130Y, YG‑180Y, YG‑200Y) delivers drilling depths of 130m, 180m, and 200m, with open hole diameters up to 325mm and end hole diameter of 75mm. The rigs support three practical coring methods: conventional core tube, SPT (standard penetration test) for soil bearing capacity, and wireline coring (NQ/HQ tools) – giving operators the versatility to adapt to different geological conditions.
Key features include a hydraulic auto‑feed system that significantly boosts efficiency while reducing manual labor, a ball chuck for safe and easy non‑stop rod handling, and a downhole pressure gauge for real‑time hole monitoring. The compact, lightweight design (as low as 600 kg without power unit) allows full disassembly for easy transport by pickup truck or small trailer. Spindle speeds range from 64 to 1045 r/min depending on model, and the winch pull force reaches up to 2500 kg. This dual‑purpose workhorse is ideal for geotechnical surveys, hydrogeological investigations, and water wells where core quality, portability, and rugged performance are paramount. YG also offers international packaging (wooden crates + plastic film) and overseas technical support.
💧 Small Borehole Drilling Machine – YG Blue Diamond Series
When portability and speed are critical, the YG Blue Diamond small borehole drilling machine redefines lightweight drilling. Weighing only 200 kg, the machine can be deployed from a standard pickup truck and ready to drill in under 30 minutes. Available with a 22HP or 30HP diesel engine (YG‑240‑22P / YG‑240‑30P), it reaches a maximum depth of 200 meters with borehole diameters from 100 mm to 280 mm. The rotary drilling process uses mud circulation to lift cuttings and stabilize the hole; the hydraulic feed system provides consistent downward pressure, while the one‑button start panel allows an ordinary operator to work independently after just 1‑2 hours of training.
The machine excels in multiple geological conditions including soil, sand, and weathered rock. It achieves 50% higher single‑hole efficiency than traditional small equipment, making it ideal for rural water supply, farm irrigation, geothermal loop installation, exploration boreholes, and monitoring wells. Drill rod diameter is 42mm or 51mm, rod change is via full automatic screw thread, and lifting force reaches 1000‑2000 kg. YG provides 24/7 online/video technical guidance and, if needed, can send professional technicians overseas for on‑site maintenance. Customization for overseas voltage standards is also available.
