TR138D rotary drilling rig is new designed self-erecting rig which mounted on original Caterpillar 323D base, adopts advanced hydraulic loading back technology, integrates advanced electronic control technology. The whole performance ofTR138D rotary drilling rig has reached advanced world standards.
TR138D rotary drilling rig has adopted CAT C6. 4 engine with ACERTTM Technology offers more engine power and runs at lower for better fuel efficiency and reduced wear. turbo suction, supply 147 hp power, Optimal machine performance, more power output, less emission.
Advanced Hydraulic & Stability Design
TR138D rotary drilling rig has new designing original hydraulic system. Hydraulic systems adopt Rexroth motor and valve, ensure power high efficiency when and where required. Wide crawler provides lower grounding pressure and improves the whole machine stability and adaptability. It is easy to work and transport by extendable crawler TR138D has separated auxiliary winch collocated on the mast from triangle parts, good view and maintenance more convenient, Compacted Parallelogram structure to reduce the length and height of the whole machine, reduce the machine, s request for the work space, easy for transportation.

Intelligent Control & Operations
Electric Control & Components: Electric systems are from Pal-fin auto-control, optimal design of electric control system improves the control accuracy and the feedback speed. All of key components adopted first class international brand, increase the interchangeability and running stability, more reasonable depth measuring device.
The newest designed winch drum structure which the service life of steel wire rope extend to 3000m.
TR138D has a large-space soundproofed cabin with high-power air condition and luxurious damping seat provides driver high-comfort and pleasured working environment. At two side, there are very convenient and humanization-designed operating joystick, Touch screen and monitor show the parameters of system includes warning device for abnormal situation. The pressure gage can also provide more intuitive working condition for the operating driver. It has the pre-automatic detection function before starting the whole machine.
Design Principles & Field Application
TR138D rotary drilling rig is new designed self-erecting rig which mounted on original Caterpillar 323D base, adopts advanced hydraulic loading back technology, integrates advanced electronic control technology. The whole performance of TR138D rotary drilling rig has reached advanced world standards.
Key Applications:

- Drilling cased bore piles (casing driven by rotary head or optionally by casing oscillator)
The corresponding improvement on both structure and control which makes the structure more simple and compact, the performance more reliable and the operation more humanized.
Frequently Asked Questions (FAQ)
What engine is utilized in the TR138D rotary drilling rig?
The TR138D features a CAT C6.4 engine with ACERT Technology delivering 147 hp, designed for optimal performance, reduced emissions, and high fuel efficiency. There is also a Cummins/CAT engine configuration option.
How does the extendable crawler assist in field operations?
The wide crawler design lowers grounding pressure, vastly improving stability and adaptability on challenging terrains. Because it is extendable, it can be retracted for easy transport.
What are the maximum drilling capabilities of the TR138D?
The drilling rig offers a maximum drilling diameter of 1500 mm and reaches a maximum drilling depth of 40/50 meters.
What components ensure the quality of the hydraulic and electrical systems?
The hydraulic system employs premium Rexroth motors and valves, while the electrical systems are powered by Pal-fin auto-control. All key parts are sourced from first-class international brands to guarantee stability and interchangeability.
What kind of operator comfort features does the cabin offer?
It includes a large, soundproofed cabin equipped with high-power air conditioning, a luxurious damping seat, user-friendly joysticks, and an advanced touch screen monitoring system with pre-automatic diagnostic functions.
Which drilling applications is the TR138D best suited for?
The machine is optimized for drilling with telescopic friction or interlocking kelly bars as standard, and for drilling cased bore piles (driven by either the rotary head or an optional casing oscillator).
