Key Features & Technical Advantages
High Pressure System: Each operating device adopts a high-pressure design with a maximum pressure of 35MPa, achieving high power and full load work.
Intelligent Electronic System: Utilizes Pal-fin auto-control. The optimized design improves control accuracy and feedback speed. Includes an advanced automatic/manual switch to guarantee verticality during operation.
Optimized Winch Design: TR230D features a separated auxiliary winch positioned on the mast from triangle parts for easier maintenance. The main winch includes touch-bottom protection, priority control, and fast line speed to minimize ineffective working time. The latest designed winch drum structure avoids wire rope tangling to extend its service life.
Compacted Parallelogram Structure: Reduces the overall length and height of the machine, minimizing workspace requirements and enabling easy transportation.
Professional Rotary Head: Equipped with BONFIGLIOLI or BREVINI reducer, and REXROTH or LINDE motor. Available in three drilling modes: standard, low speed with big torque, or high speed with small torque (spin-off is optional).
Heavy Damping System: Features a heavy damping spring base with multilevel shock absorption design to ensure greater operational safety.
Advanced Lubrication & Depth Measurement: The special lubricating system ensures the rig can work in extreme high or low temperatures, prolonging the rotary head's service life. Equipped with a highly accurate depth measuring device.
Luxurious Operator Cabin: Soundproofed cabin with high-power air conditioning, luxurious damping seat, humanized joysticks, touch screen monitor, warning systems, and pressure gauges. Features pre-automatic system checks before machine start.

Drilling cased bore piles driven by rotary head or optionally by casing oscillator.
CFA Piles
Constructing CFA Piles by means of continuous flight auger systems.
Displacement Piles
Supporting either crowd winch systems or hydraulic crowd cylinder systems for displacement piles and soil-mixing.
Frequently Asked Questions (FAQ)
What type of chassis and engine does the TR230D use?
The TR230D is built on an original retractable Caterpillar 336D chassis base and is equipped with a high-performance Scania or CAT turbocharged engine to ensure stability and efficiency across various construction environments.
What are the maximum drilling capabilities of the TR230D?
The TR230D rotary drilling rig supports a maximum drilling diameter of 2000 mm and can reach a maximum drilling depth of 54 to 68 meters depending on the configured setup.
How does the adjustable crawler width help in operation?
The crawler width can be adjusted from 3000 mm to 4300 mm. This adaptability allows the rig to maintain maximum stability during drilling operations and contract to a narrower footprint for easier transportation.
What kind of hydraulic components are integrated into the system?
The rig integrates a Caterpillar hydraulic system for its main and pilot circuits. It uses world-famous brands like Rexroth and Parker to guarantee high reliability, precision control, and efficient flow distribution.
What drilling modes are available for the rotary head?
The professional rotary head is available in three distinct drilling modes: standard mode, low speed with big torque, and high speed with small torque. Spin-off operation is also optionally available.
How is operator comfort and safety managed in the cabin?
The spacious, soundproofed cabin features high-power air conditioning, a luxurious damping seat, and ergonomic control joysticks. It also includes a touch screen monitor showing real-time system parameters, abnormal condition warnings, and an automatic pre-start system check.
