Features and advantages of TR280 CFA rotary drilling rig:


1. The power head of TR280W CFA rotary drilling rig 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 of TR280W CFA rotary drilling rig 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. CAT C-9 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 ondemand distribution of the flow. Rexroth motor and balance valve are chosen for the main winch.

5. 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.

6. TR280W CFA rotary drilling rig is no need to disassemble the drill pipe before transporting which is transition convenient. The whole machine can be transported together.

7. The width of chassis is 3m 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.
