Frequently Asked Questions
Q: What formations can TRD-800 handle effectively? +
A: Based on working formation parameters, TRD-800 drills in loose soil and bedrock with hardness F6–20. The combination of mud drilling and DTH hammer ensures high penetration in gravel, clay, and hard rock layers without frequent bit changes.
Q: What is the maximum depth for mud drilling and pneumatic drilling? +
A: According to technical specs: mud drilling reaches 1000m, pneumatic drilling (DTH hammer) up to 800m, and NQ wireline coring extends to 1200m. The top-drive system offers consistent torque up to 16500N·m.
Q: How does the mechanical top-drive improve drilling efficiency? +
A: The mechanical transmission spindle improves efficiency by 100% compared to conventional hydraulic systems, reduces energy consumption, while the long-stroke speed multiplying mechanism reduces stuck and burned drill incidents.
Q: Can I adapt additional hydraulic functions on this rig? +
A: Yes, the hydraulic control system includes reserved ports for functional extensions based on specific user requirements, making TRD-800 customizable for auxiliary equipment.
Q: What is the crawler chassis climbing ability and travel speed? +
A: TRD-800 self-propelled crawler offers travel speed 0-2km/h and climbing ability 25°~30°, suitable for rough terrain and job site relocation.
Q: What are the air consumption requirements for DTH drilling? +
A: Matching air compressor must supply total air consumption 16~35 m³/min at working pressure 10.5~24.6 bar to achieve optimum pneumatic hammer performance.
