Instructions
The YONDA YSD700A combines vibration and rotation for shallow environmental investigations, groundwater monitoring wells, light-duty geological sampling, small geothermal boreholes and small water wells.
It delivers a maximum vibration force of 38 kN and a maximum vibration frequency of 4,000 cycles per minute (approximately 66.7 Hz). The rotation unit features two gear ranges with stepless speed control: 0–48 rpm at 5,400 Nm and 0–96 rpm at 2,700 Nm. Operators can select the appropriate range to suit the drilling tools and operating requirements.
Hydraulic motor drives, an air damper and a maintenance-friendly structure make the YSD700A an option for drilling rig manufacturers and contractors evaluating vibration drilling head integration.
An integrated air/water inlet mechanism supports various drilling and flushing requirements, while the robust and maintenance-friendly structure is designed for reliable field operation.

FAQ
1. What applications is the YSD700A suitable for?
The YSD700A is intended for shallow environmental investigations, small groundwater monitoring wells, light-duty geological sampling, small geothermal boreholes and domestic water wells. Suitability depends on ground conditions, borehole diameter, drilling depth, tooling and rig configuration.
2. What are the vibration force and frequency of the YSD700A?
The maximum vibration force is 38 kN, and the maximum vibration frequency is 4,000 cycles per minute, equivalent to approximately 66.7 Hz. These are catalog maximum values; actual operation depends on the hydraulic supply and working conditions.
3. How does the two-range rotation system work?
The first gear range provides 0–48 rpm with a rotation torque of 5,400 Nm. The second provides 0–96 rpm with 2,700 Nm. Stepless speed control within each range allows operators to adjust rotational speed and select the range appropriate for the task.
4. Can the YSD700A be fitted to an existing drilling rig?
Retrofit suitability requires a review of the mounting interface, rig load capacity, feed and pullback capacity, hydraulic supply and control system. Please provide the rig model, mounting dimensions and hydraulic specifications for an integration assessment.
