ZOOMLION ZR140 Rotary Drilling Rig

ZOOMLION ZR140 Rotary Drilling Rig.
The newly upgraded ZR140 is not only highly efficient in construction and retains its value, but is also transported with rods, has a small grounding ratio pressure, comes standard with 355*10 drill rods, has a hole diameter of 1300mm and a maximum drilling depth of 44m, making it a real helper for you to get rich.

ADVANTAGE INTRODUCTION
- The whole machine can be transported with Kelly bar to realize quick transfer between operation and transportation.
- Cummins engine with reliable performance and strong output power.
- High construction efficiency, thanks to adoption of large displacement main pump and optimizing power system.
- Less fuel consumption, thanks to adoption of a new generation of electronic control platform and proportional control hydraulic system.
- The auxiliary winch can lift Dia.0.8m steel cage (with a Kelly bar).
- Automatic multi-self-checking, safety and performance monitoring.
- Options: Spin-off, auto-lubrication.
