TR468H rotary drilling rig
The TR468H rotary drilling rig is a large-scale piling machine. It is particularly suitable for projects requiring large-diameter, deep-hole piles for cross-sea and cross-river bridges in areas with complex geological conditions. It boasts advantages such as high stability, large pile diameter, deep pile holes, and easy transportation.
Model : TR468
Max. Drilling Depth: 110m;
Drilling diameter: 3000mm;
Torque: 450KN.m;
Undercarriage: Original CAT base or Self undercarriage

Main Features:
- Employs a large triangular support structure to reduce the turning radius and enhance drilling stability.
- Utilizes a rear-mounted main winch with dual motors, dual reducers, and a single-layer large drum design, avoiding the “rope biting” phenomenon caused by double-layer rope winding.
- Employs a wire rope pressurization method with a 12-meter pressurization stroke, providing high pressure and long stroke, facilitating the installation of protective casing.
- Optimized hydraulic and electrical control system design improves system control accuracy and response speed.
- Employs a patented hole depth measuring device, enhancing depth measurement accuracy.
- Unique dual-mode design allows it to meet the requirements of extra-large piles and rock penetration.
