Adopt single rope main winch, effectively solving the wear problem of the steel wire rope and improving its service life.
- Install the infrared camera, which can observe the service condition of the main winch steel wirerope in the cab day and night.
- Many configurations can be installed according to the customers’ requirements (such as: landing leg cylinder, automatic slew).
- Adopt imported Cummins electronic control turbocharging engine, meeting the Europe III emission standard. It is energy-efficient and environmental friendly, and has strong power.
- The hydraulic system adopts limiting power control and positive flow control, which improves the efficiency of the hydraulic system and saves more energy.
- The patent parallelogram variable structure realizes the large-scope working area. The mast is designed to be the box-type structure, which has high intensity and rigidity, effectively ensuring the drilling preciseness.
- It can be attached with 5 drill rods. The maximum drilling depth can reach 67.5m.
