overview

Applicable to the railways, highways, Bridges, dam foundation, and various industrial and civil building foundation treatment and reinforcement of jet grouting construction;Anchoring engineering of foundation pit support;Equipped with air compressor and pneumatic hammer, it can be used for following pipe drilling, general rotary jet (swing jet, fixed jet) engineering construction, but also for shallow hole drilling and engineering survey drilling and other engineering construction.

Main Features

1. Full hydraulic control, easy and flexible operation, crawler chassis loading, easy and quick walking and moving to position, long travel of power head, reducing auxiliary time.

2. Direct-acting load feedback fine-tuning variable hydraulic system, with power varying with load, high efficiency and low energy consumption.

3. The rotary adopts a special valve with friction positioning, whose characteristics fully meet the requirements of rotary jet process.

4. The power head variable speed range is wide, can meet the requirements of various strata and different drilling technology.

5. Equipped with slewing support, the hole can be turned to the side of the track when needed.

6. Compact structure, centralized operation, convenient and safe.

7. Display device for vertical drilling tower, power head rotation and lifting speed.

Supporting Drilling Tools
