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.
