Frequently Asked Questions
🔹 What formations can the TRD-300 handle?
Based on technical parameters, the TRD-300 works efficiently in loose soil, gravel layers, and bedrock with hardness F6–20. Dual water/air method ensures optimal penetration in mixed conditions.
🔹 What is the maximum drilling depth with mud circulation?
The drill rig achieves mud drilling depth up to 530 meters. For pneumatic DTH hammer drilling, maximum depth is 300 meters. NQ wireline coring extends to 600 meters, making it suitable for exploration projects.
🔹 What air compressor is recommended for pneumatic drilling?
Matching air compressor should supply total air consumption of 16–35 m³/min with working air pressure between 10.5 and 24.6 bar. This ensures optimal performance of the DTH hammer.
🔹 Which drill rod sizes are compatible?
TRD-300 accepts rod diameters φ50, φ76, φ89, and φ102 mm, with standard rod length of 3000 mm. This range covers most exploration and water well drilling requirements.
🔹 What is the torque and rotary speed of the power head?
Power head delivers maximum torque of 5000 N·m and infinitely variable rotary speed from 50 to 1020 r/min, providing excellent control for both soft and hard formations.
🔹 Does the rig have good mobility on rough terrain?
Yes, equipped with a heavy-duty crawler chassis offering travel speed 0–2 km/h and climbing ability up to 20°, ensuring stable transportation on construction and mining sites.
🔹 What is the transport dimension and weight?
Transport dimensions: 5380×1575×2500 mm, machine weight 4380 kg. Compact enough for flatbed or container shipping, yet robust in operation.
