Borehole Drilling Rig Building Construction Machine Rotary Spray Drill
ZXL50 rotary spray drill Building Construction Machine
This equipment is suitable for foundation treatment and reinforcement in various industries and civil constructions, including railways, highways, bridges, dam foundations, etc. In addition to performing general rotary spraying (swing spraying, fixed spraying) construction projects, it can also be used for shallow hole drilling and engineering exploration drilling.
Features:
1.High drilling capacity.
2. Equipped with a fully hydraulic power head transmission system, offering stepless speed control, high drilling efficiency, and low labor intensity.
3.Direct-drive load feedback fine-tuning variable hydraulic system, with power adjusting according to the load, ensuring high efficiency and low energy consumption.
4. For the first time among similar domestic drilling rigs, it incorporates imported special friction positioning valves that fully meet the requirements of rotary spraying technology.
5. Wide range of power head speed variations, catering to different geological formations and drilling techniques.
6.Equipped with crawler chassis for convenient and quick walking and positioning.
7. Equipped with a rotary bearing, allowing the hole position to be rotated to the side of the crawler for operation when needed.
8. Long power head stroke, reducing auxiliary time.
9.Compact structure, centralized operation, convenient and safe.
10. Equipped with displays for vertical tower, power head rotation, and lifting speed, facilitating monitoring and control.
