Features and advantages of TR60:
- The rotary head has the function of spin off speed; the maximum rotation speed can reach to 80r/min. It completely solves the problem of soil off difficulty for small diameter pile hole construction.
- The main and auxiliary winch are all located on the back of mast which are easy to observe the direction of the rope. It improves the mast stability and construction safety.
- Cummins engine is chosen to meet the state III emission requirements with economic, efficient, environmentally friendly and stable characteristics.
- The hydraulic system adopts the international advanced concept, specially designed for the rotary drilling system. Main pump, rotary head motor, main valve, service valve, travelling system, rotary system and the joystick are all import brand. The auxiliary system adopts the load-sensitive technology to realize the on-demand distribution of the flow. Rexroth motor and balance valve are chosen for the main winch.
- It is no need to disassemble the drill pipe before transporting. The whole machine can be transported together.
- All the key parts of the electric control system (such as display, controller, and the inclination sensor) adopt international famous brands EPEC from Finland, and use aviation connectors to make special products for domestic projects.
