Low maintain cost Diameter 3000mm Rotary Drilling Rigs Bore Hole For Deep Foundation

TR460D Rotary Drilling Rig Diameter 3000mm Bore Hole  For Deep Foundation

TR460D rotary drilling rig is large pile machine. Currently, the large tonnage rotary drilling rig is widely used by the customers in the complex geologyarea. What's more, the large and deep hole piles are required in the across sea and across river bridge. Thus, according to the above two reasons, we researched and developed TR460D rotary drilling rig which has the advantages of high stability, large and deep pile and easy for transportation.

TR460D Main Technical Specification:

Feature and advantages of TR460D rotary drilling rig:

1. Triangle support structure reduces turning radius and increases the stability of rotary drilling rig.
2. Rear-mounted main winch uses double motors, double reducers and single layer drum design which avoids rope winding.
3. Crowd winch system is adopted, stroke is 9m. Both crowd force & stroke are larger than those of cylinder system, which is easy to embed casing.
4. Optimized hydraulic and electrical control system improves system control accurancy and reaction speed.
5. Authorized utility model patent of depth measuring device improves the accuracy of depth measurement.
6. Unique design of one machine with double working conditions can meet the requirements of large piles and rock-entry.
