Key Features & Advantages
✓
High Torque Capacity: Max torque of SD2000 hydraulic crawler core drilling rig is 4263Nm, satisfying different project construction and drilling process demands.
✓
Optimized High-Speed Drilling: Max speed of the SD2000 hydraulic crawler core drilling rig is 1120 rpm with torque 680Nm. It features high torque at high speed, suitable for deep-hole drilling.
✓
Efficient Feeding & Lifting: The feeding and lifting system uses a piston hydraulic cylinder to drive the rotation head directly with a long travel and high lifting force, convenient for deep-hole core drilling work.
✓
Time-Saving Operation: High lifting speed saves significant auxiliary time. It is easy to wash the hole when performing the full driving operation, enhancing overall drilling efficiency.
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, this 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: The main winch is an imported product with NQ2000M single rope steady and reliable lifting ability. The wire line winch reaches a max speed of 205m/min at empty drum, saving auxiliary time.
✓
Clamp & Unscrew System: Equipped with a clamp and unscrew machine, making it easy to disassemble the drilling rod and reducing labor intensity.
✓
Pressure-Balancing Tech: The feeding system adopts back pressure-balancing technology. Users can conveniently adjust drilling pressure at the bottom of the hole, increasing drill bit life.
✓
Reliable Hydraulics: The hydraulic system is reliable, and both mud pump and mud mixing machine are hydraulically controlled. The integrated operation makes it easy to handle bottom-hole incidents.
✓
Self-Propelled Mobility: Crawler movement is linearly controlled, safe, and reliable. It can climb onto flat trucks independently, eliminating cable car costs, ensuring high reliability and low maintenance/repair costs.
Frequently Asked Questions (FAQ)
What are the drilling depth capacities of the SD2000?
The drilling rig supports depths of up to 2500m for BQ (Ф56mm), 2000m for NQ (Ф71mm), and 1400m for HQ (Ф89mm) diameter drilling.
What type of engine powers this drilling rig?
The SD2000 is powered by a reliable Cummins diesel engine, model 6CTA8.3-C260, delivering 194KW of power at 2200rpm.
What is the primary application of the SD-2000 rig?
It is primarily designed for diamond bit drilling with wire line. Additionally, it is widely used for seismic geophysical exploration, engineering geological investigation, micro-pile hole drilling, and small/medium water well construction.
How does the clamp and unscrew system benefit operators?
It simplifies the process of disassembling the drilling rod, which greatly reduces the physical labor intensity and increases operational safety.
Can the SD2000 crawler load itself for transportation?
Yes. The crawler features linear control with a maximum transit sloping angle of 30° and a maximum loading of 20t, allowing it to climb onto flat transportation trucks independently.
How does the back pressure-balancing technology improve drilling efficiency?
It allows operators to conveniently adjust and balance the drilling pressure at the bottom of the hole, which helps extend the operational lifespan of the drill bits.
