TR408H rotary drilling rig
The TR408H rotary drilling rig is a large-scale piling machine, It can be equipped with various drilling tools, such as short auger bits, rotary buckets, and core drill buckets, for hole-forming operations. Due to its high torque, high pressure, high construction efficiency, pollution-free operation, and multi-functionality, it is widely used in the foundation construction of roads, bridges, and high-rise buildings in my country.
Model : TR408
Max. Drilling Depth: 95/110m;
Drilling diameter: 2500mm;
Torque: 380KN.m;
Undercarriage: Original CAT base or Self undercarriage
Model : TR408
Max. Drilling Depth: 95/110m;
Drilling diameter: 2500mm;
Torque: 380KN.m;
Undercarriage: Original CAT base or Self undercarriage
Main Features:
- Adopts a large triangular support structure, reducing the turning radius and enhancing the drilling rig’s 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 wire rope pressurization, with a standard pressurization stroke of 9 meters and an optional stroke of 14 meters. High pressurization pressure and long pressurization stroke facilitate 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, improving depth measurement accuracy.
