We are pleased to share on-site photos from our customer in Zambia, where our CR-15 Full Hydraulic Surface Core Drilling Rig is running smoothly for mineral exploration work. This high-performance core drilling unit stands out with solid configuration, powerful output and strong terrain adaptability, perfectly matching local complex geological working conditions.
Core Configuration & Power
The rig is driven by a WP6G240E330 diesel engine with a rated power of 176 kW (240 HP) and a rated speed of 2200 rpm, delivering sufficient and stable power for long-hour field operation. All core hydraulic components are sourced from world-famous brands: rotation motors and main winch reducers from Rexroth, hydraulic pumps and main control valves from Danfoss, and secondary winch motors from Eaton. Premium imported parts greatly reduce failure rates and extend service life.
Outstanding Drilling Capacity
It supports a full range of standard drill rods. The maximum drilling depth reaches 2050m for BQ rods, 1650m for NQ rods, 1350m for HQ rods and 950m for PQ rods, fully meeting the demands of deep mineral exploration. The drill head adopts two-speed hydraulic motor with stepless speed regulation from 0 to 1250 RPM, and the maximum torque hits 6200 N·m. Equipped with a 243 kN hydraulic chuck, it provides firm clamping force for drilling rods.
Working Performance & Structure
This rig features a 25-ton pullback force and a 3.7 m feed stroke, and it supports 3m or 6m rod pulling. The main hoist has a single-line lifting force of 120 kN, while the wireline hoist offers 15 kN lifting force with a 2200m steel wire rope, covering deep-hole operation needs. The mast can be adjusted from 45° off horizontal to 90° vertical, realizing multi-angle drilling.
A professional mud pump is equipped, with a flow rate of 250 L/min and discharge pressure of 8.0 MPa, ensuring smooth mud circulation. The spring-close & hydraulic-open foot clamp works reliably for safe operation. The centralized control panel and independent cooling system make operation simpler and keep the machine stable during continuous work.
Mobility & Specification
Weighing 10.5 tons, the whole machine adopts a steel crawler chassis, which adapts well to rugged mine roads and realizes flexible movement. Its transport dimension is 5880×2240×2480 mm, convenient for transportation and site transition.
Certified with ISO quality management system and CE machinery safety standard, CR-15 is a reliable choice for global geological and mineral exploration. Thanks to the recognition from our Zambian customer. We will keep optimizing our drilling equipment to serve more overseas projects.
