Professional KR300ES: High-Quality Low Headroom Piling Rig
Hydraulic Rotary Drilling Rig
Product description
1. Advanced Rotary Angle Displacement Output Mechanism:
The KR300ES hydraulic rotary drilling rig is equipped with an
advanced rotary angle displacement output mechanism. This mechanism
ensures precise control and accurate drilling angles, enhancing the
overall performance and efficiency of the rig.
2. Innovative Drilling Bucket Depth Measurement System:
Our piling rig features an innovative drilling bucket depth
measurement system. This system provides real-time feedback on the
depth of the drilling bucket, allowing operators to monitor and
adjust the drilling process with precision and confidence.
3. Priority Control Function:
The KR300ES rig incorporates a priority control function,
optimizing the allocation of power and resources for enhanced
efficiency and productivity. This feature ensures smooth operation
and reduces downtime, maximizing the output of the drilling rig.
4. Reversible Head Design:
The drilling rig's head is designed for reversibility, offering
versatility and convenience during drilling operations. This design
allows for efficient drilling in both clockwise and
counterclockwise directions, adapting to specific project
requirements with ease.
5. Automatic Mast Vertical Adjustment for Enhanced Hole Accuracy:
The mast of the KR300ES drilling rig is equipped with an automatic
vertical adjustment system. This system enhances the accuracy of
hole drilling by automatically adjusting the mast to maintain
vertical alignment. This feature ensures precise and consistent
hole drilling, minimizing errors and optimizing productivity.
