TR120D Rotary Drilling Rig

TR120D rotary drilling is new designed self-erecting rig, which adopts advanced hydraulic loading back technology, integrates advanced electronic control technology. The whole performance of TR120D rotary drilling rig has reached advanced world standards.

The corresponding improvement on both structure and control, which makes the structure more simple and compact the performance more reliable and operation more humanized.  

It is suitable for the following application: 

Drilling with telescopic friction or interlocking Kelly bar – standard supply.

Drilling with CFA drilling system –optional supply

Features and advantages of TR120D:

1. The power head has the function of high-speed soil rejection; the maximum speed can reach to 70r/min. It completely solves the problem of soil rejection difficulty for small diameter pile hole construction.

2. The main and vice winch are all located in the mast which are easy to observe the direction of the rope. It improves the mast stability and construction safety.

3. Cummins QSB4.5-C60-30 engine is chosen to meet the state III emission requirements with economic, efficient, environmentally friendly and stable characteristics.

4. The hydraulic system adopts the international advanced concept, specially designed for the rotary drilling system. Main pump, power head motor, main valve, auxiliary valve, walking system, rotary system and the pilot handle are all import brand. The auxiliary system adopts the load-sensitive system to realize the on-demand distribution of the flow. Rexroth motor and balance valve are chosen for the main winch.

5. It is no need to disassemble the drill pipe before transporting which is transition convenient. The whole machine can be transported together.

6. All the key parts of the electric control system (such as display, controller, and the inclination sensor) adopt imported components of international famous brands EPEC from Finland, and use air connectors to make special products for domestic projects.
7. The width of chassis is 3.9m which can work stability. The superstructure is optimizing designed; engine is designed at the side of the structure where all components are located with rational layout. The space is large which is easy for maintenance. The design can avoid the narrow space defects which the machine is modified from an excavator.
