The JTHC‑600 crawler‑mounted core drilling rig by Master Group is a multi‑purpose full‑hydraulic exploration unit built for wireline coring work. It retrieves rock cores through drill rod inner bore via dedicated winch, ideal for solid mineral prospecting, engineering geological surveys, shallow oil‑gas & groundwater drilling, as well as tunnel drainage and dam grouting projects.
Built for rough field sites, this wireline coring rig features load‑sensing hydraulics and heavy‑duty structures to ensure stable deep‑hole coring performance.
Wireless remote‑controlled crawler chassis: Safe remote travelling across uneven terrain.
Robust welded frame & slide frame: Hot‑rolled steel guides with throttle‑valve controlled smooth cylinder movement for enhanced rigidity.
Touchdown integrated drill tower: Ground‑contact base improves drilling stability; adjustable drilling angle 45°‑90°, 800 mm slip stroke, 6.1 m full height.
Power‑head rotary & feed system: Axial piston drive with 2‑gear mechanical shift + stepless speed regulation. Cylinder‑chain double‑speed feeding plus power‑head side‑shift for easy rod handling.
Hydraulic clamp & wire‑line coring winch: Hydraulic clamp secures drill rods; winch offers 800 m rope capacity for efficient core retrieval.
4‑point hydraulic outriggers: Quick rig levelling with hydraulic locks to prevent jack creep.
Centralized console & dual cooling: All‑in‑one control for simple operation. Air‑water combined cooling supports long‑hour heavy‑load work.
Yuchai 4‑cylinder diesel power: 92 kW reliable engine with accessible after‑sales support.
