Key Features & Performance
High Pressure Design & Controls
Each operating device adopts a high-pressure design (max pressure 35MPa) to achieve high power and full load work. Electrical systems feature Pal-fin auto-control for optimized accuracy and response speed, with manual/automatic switches to maintain verticality during operations.
Winch & Mast Design
Features a separated auxiliary winch collocated on the mast from triangle parts for easier maintenance and visibility. The main winch highlights touch-bottom protection, priority control, and fast line speed, avoiding wire rope tangles and extending rope service life.
Compact Structure & Easy Transport
The compacted parallelogram structure reduces the overall length and height of the machine. This minimizes the working space requirement and ensures convenient transportation.
Professional Rotary Head
Equipped with a BONFIGLIOLI or BREVINI reducer and a 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.
Safety & Heavy Damping
Heavy damping spring design on the base provides multilevel shock absorption for greater operation safety. Special lubricating system enables performance in high or low temperature environments, prolonging the rotary head's service life.
Ergonomic Soundproof Cabin
A spacious soundproof cabin features high-power AC, luxurious damping seats, humanized joysticks, a touch screen monitor, and an abnormal situation warning device. Pressure gages and pre-automatic start-up detection ensure high control comfort.
Applications
The TR230D Rotary Drilling Rig is a self-erecting rig mounted on an original Caterpillar 336D base, designed to integrate advanced electronic controls and hydraulic loading back technology for worldwide application standards. It is specially designed to suit the following applications:
Drilling with telescopic friction or interlocking kelly bar (standard supply).
Drilling cased bore piles (casing driven by rotary head or optionally by casing oscillator).
CFA Piles by means of continuous flight auger.
Crowd winch system or hydraulic crowd cylinder system applications.
Displacement piles and soil-mixing operations.
Frequently Asked Questions (FAQ)
Q
Which engine model and base chassis are used for the TR230D?
The TR230D Rotary Drilling Rig is built on an original Caterpillar 336D base. It is powered by a high-performance SCANIA or CAT engine with a rated output of 232 kW at 2200 r/min.
Q
What are the maximum drilling capabilities of this machine?
The TR230D is capable of achieving a maximum drilling diameter of 2000 mm and a maximum drilling depth between 54 and 68 meters.
Q
How adjustable is the crawler track system?
To accommodate different stability demands and job site environments, the crawler width can be flexibly adjusted within a range of 3000 mm to 4300 mm.
Q
What safety mechanisms are built into the main and auxiliary winches?
The main winch includes advanced features such as touch-bottom protection, priority control, and fast line speed. Additionally, the updated drum design prevents wire rope tangling to increase its overall lifespan. The auxiliary winch is separated on the mast for superior visibility and maintenance.
Q
What are the primary applications of this rotary drilling rig?
The rig is engineered for drilling with telescopic friction or interlocking kelly bars, drilling cased bore piles (driven by rotary head or casing oscillator), CFA piles using a continuous auger, displacement piles, and soil-mixing operations.
Q
How does the hydraulic design ensure efficiency?
It incorporates a high-pressure design (max 35 MPa) for full-load capacity. Using Caterpillar main and pilot circuits along with high-quality components from Rexroth and Parker, the flow is dynamically distributed to matching systems based on current load needs.
