The CSD2500L full hydraulic crawler surface core drill rig is a high-performance drilling machine developed by CORTECH for solid mineral exploration. Integrating hydraulic drive, intelligent control, and modular design, it is compatible with advanced technologies such as diamond wireline coring, significantly improving core recovery rates and operating efficiency in complex formations. Its high-speed, precise control, long feed stroke, and full hydraulic drive system meet the demands of a variety of demanding working conditions, making it an ideal choice for geological exploration and mineral development.
1. Efficient and Intelligent Operation
• Equipped with an intelligent control system and wireless remote control, it provides convenient and safe operation.
• The side-sliding chuck driven drill head design allows for quick hole clearance, significantly improving coring and drilling efficiency.
• The nitrogen spring clamping device ensures long-term stable chuck operation and reduces maintenance frequency.
2. Powerful Power and Environmental Compatibility
• Equipped with a Cummins QSB diesel engine (China III emission standard), it offers powerful power and low carbon footprint.
• Internationally mainstream hydraulic components (pumps, motors, and valve blocks) ensure long-term, high-load operational reliability.
3. Flexible Adaptability to Complex Working Conditions
• The hydraulically controlled, self-propelled crawler chassis allows for easy relocation and adaptability to rugged terrain.
• The sliding mast, main and wireline winches, and orifice-clamping device optimize the drilling process and reduce labor intensity.
4. Safe and Humanized Design
• The auxiliary operating console independently controls the mast lift and lowering for operations that are more efficient.
• Multiple functional safety features, including hydraulic overload protection and emergency braking, ensure the safety of personnel and equipment.
