FAQ
1. What applications is the YDH602 suitable for?
The YDH602 is suitable for anchoring, water well and Ø146 mm casing drilling. Application suitability depends on ground conditions, tooling and drilling rig capacity.
2. What rotation speeds and torque outputs are available?
The two-speed system provides a maximum of 92 rpm with 5,750 Nm in the first setting, or 46 rpm with 11,500 Nm in the second. Switching the hydraulic circuit allows operators to select the setting required for the drilling task.
3. Does the YDH602 offer different percussion frequencies?
The YDH602 offers three percussion frequency options. The catalog lists a percussion frequency of 2,500 bpm (blows per minute). Contact YONDA to confirm the available options and their hydraulic requirements.
4. What should be checked before installing the YDH602 on a drilling rig?
Check the hydraulic supply, mounting dimensions, tooling connection and mast load capacity. The catalog specifies 180 bar and 70–90 L/min for percussion, and 205 bar and 170 L/min for rotation. The head weighs 550 kg. Provide your rig specifications and drilling requirements to YONDA for configuration assessment.
