Product Description

TR460 Rotary Drilling Rig is a large pile machine. Currently, the large tonnage rotary drilling rig is widely used by customers in complex geology areas. What's more, large and deep hole piles are required in across-sea and across-river bridges. Thus, according to these crucial needs, we researched and developed the TR460 rotary drilling rig, which has the advantages of high stability, large and deep pile capabilities, and easy transportation.

Triangle support structure reduces turning radius and increases the stability of the rotary drilling rig.

Rear-mounted main winch uses double motors, double reducers, and single-layer drum design which avoids rope winding.

Crowd winch system with 9m stroke provides larger crowd force & stroke than cylinder systems, facilitating casing embedment. Optimized hydraulic and electrical systems improve response speed.

Authorized utility model patent of depth measuring device improves the accuracy of depth measurement.

Unique design of one machine with double working conditions can meet the requirements of large piles and rocketry.

Frequently Asked Questions

What are the main advantages of the TR460 Rotary Drilling Rig?

The TR460 offers high stability, large and deep pile capabilities, and is designed for easy transportation, making it ideal for complex geological conditions and large-scale bridge constructions.

What engine powers the TR460D and what is its output?

The TR460D is equipped with a high-performance CAT engine, delivering a rated power of 367 kW at a rated speed of 2200 r/min.

What is the maximum drilling depth and diameter of this rig?

The TR460D can achieve a maximum drilling diameter of 3000 mm and reaches a maximum drilling depth of 110 meters.

How does the main winch design prevent rope winding issues?

The rear-mounted main winch incorporates a single-layer drum design along with double motors and double reducers, which effectively prevents rope overlapping and winding.

What type of Kelly bars can be used with the TR460D?

It supports an interlocking Kelly bar sized at Φ580*4*20.3m, and also offers an optional friction Kelly bar sized at Φ580*6*20.3m to meet different working requirements.

How does the triangle support structure improve performance?

The triangle support structure reduces the overall turning radius of the machine, which substantially increases operational stability while working on site.
