6. Electrical drive pump for hydraulic oil refill: Used for adding hydraulic oil
7. Walking wheel
Outstanding features:
Unmatched high drill head and spindle speed, which allows high drilling speed
Full hydraulic driven and control system, including:
Hydraulic rod feeding, pushing and pulling system;
Hydraulic rod rotation driving system;
Superior quality key components made of aircraft grade materials, fabricated with
Professional aircraft industry machinery;
Power supply can be made by electrical motor/generator assembly.
Drilling angle adjustable between 0° And 360°
Advanced winching system
Flexible rotation base frame. Can easily change the direction by rotating the base

Secondary hydraulic oil filter. To make the filtration for hydraulic oil more safe, we set
Up the secondary filter in the chuck which will shows as a red point.

Magnetic prevention for hydraulic oil. Even if we have the first stage filtration for
Hydraulic oil from the oil tank, but we also set up the strong magnetic on the tank to
Absorb any chips so as to avoid it goes to next step.

Oil temperature sensor. In order to keep the temperature of hydraulic oil at safe level,
We configures with the temperature sensor in the flow to monitor and feedback during
The work.
Electrical work recorder. We configure with this electrical recorder so that there will be
Clear record and report to check how much work has been done.
4 shifts design. High and low shift by stepless shift change For hydraulic shift mode
Two shifts for mechanical shifts mode.
More advanced, more humanized, more optimized design for whole working system.
