High Torque Capacity: Max torque of SD2000 hydraulic crawler core drilling rig is 4263Nm, satisfying diverse project construction and drilling processes.
Optimized High-Speed Torque: Max speed is 1120 rpm with torque 680Nm. High torque at high speed makes it highly suitable for deep-hole drilling.
Piston Hydraulic Drive: The feeding and lifting system uses the piston hydraulic cylinder to drive the rotation head directly with a long travel and high lifting force.
Enhanced Efficiency: High lifting speed saves auxiliary time and simplifies hole washing during full driving operations, boosting overall productivity.
SD-2000 full hydraulic crawler driving core drilling rig is mainly used for diamond bit drilling with wire line. Because of the use of foreign advanced technology, especially the mature rotation head unit, clamp machine, winch and hydraulic systems, the drilling rig is widely used. It is not only applicable to the diamond and carbide drilling of solid bed, but also to seismic geophysical exploration, engineering geological investigation, micro-pile hole drilling, and construction of small/medium wells.
Imported Main Winch: Utilizes reliable lifting with NQ2000M single rope capacity. The wire line winch reaches max speeds of 205m/min at empty drum, minimizing auxiliary downtime.
Integrated Clamp & Unscrew Machine: Features quick clamp and unscrew mechanisms to facilitate easy disassembly of the drilling rod, successfully reducing physical labor intensity.
Back Pressure-Balancing: The advanced feeding system enables users to easily monitor drilling pressure at the bottom of the hole, extending drill bit working life.
Hydraulic Control: The mud pump and mud mixing machines are hydraulically controlled. Integrated operation ensures swift handling of incidents at the bottom of the hole.
Linear Controlled Crawler: Movement is safely controlled. The unit can climb onto flat trucks independently, reducing logistics and setup costs while offering high reliability.
