Excavator Rotary Drilling Rig

The Excavator Rotary Drilling Rig is a core accessory specially designed for pile foundation construction. It can be mounted on 1-50 ton excavators to achieve efficient hole formation for cast-in-place piles and supports full-scenario customization to suit various engineering needs such as building construction, bridges, and municipal projects.

The main structure of the Excavator Rotary Drilling Rig is welded from Q690 high-strength steel. The drill rod can be customized with a 3-15 meter sectional design to accommodate pile depths of 5-30 meters. The drill bit can be tailored as an auger drill (for soft soil), bucket drill (for hard rock), or sand grab drill (for silt). For complex geological conditions such as moderately weathered rock or pebble layers, alloy teeth or impact hammers can be added.

Equipped with an independent hydraulic drive system, the Excavator Rotary Drilling Rig achieves a hole formation speed of 1-3 meters per minute. Combined with a verticality monitoring device, the hole position deviation is controlled within ≤5 cm. The control system can be customized according to the excavator's hydraulic flow rate to adapt to different brand models. Key components are made of wear-resistant materials, extending service life by 40%.
Suitable for building pile foundations, high-speed railway bridge piers, and municipal pipeline network construction, the Excavator Rotary Drilling Rig offers customized solutions that can precisely match geological and schedule requirements, significantly reducing construction costs.
