Main Body
The machine body is composed of the following parts:
1. Chuck and speed reducer assembly including:
Speed reducer: Ratio 2.2: 1
Chuck and guide sleeve
Hydraulic motor

Working pressure: 20Mpa
Maximum pressure: 25 Mpa
Theoretical drainage: 80ml/r, the minimum drainage 35ml/r

2. Holder assembly
3. Bed body
Oil cylinder in bed body adopt GG012-80/40x800x1060
Chain adopt 1# and 1 1/4# two kinds of bush roller chain.
Power handcart
Power handcart is composed of the following parts:
1. Y series three-phase squirrel-cage asynchronism motor
Voltage: 380 V
Frequency: 50 Hz
Rotational frequency: 1480 r/min
Power: 55Kw
2. High pressure axial plunger pump
Motor oil way plunger pump(main pump)
Rated pressure: 31.5 Mpa

Theoretical drainage: 800 ml. /r(90% of the oil pump drainage)
Max. Theoretical torque: 439.6 Nm
Feed oil cylinder oil way plunger pump(service pump)
Rated pressure: 31.5 Mpa
Theoretical drainage: 10.9 ml/r
Max. Theoretical torque: 54.8 Nm
3. Oil filter
Filtration accuracy: 10 μ M
4. Cooler
Oil pressure: 1.6 Mpa(max)
Water pressure: 1 Mpa(max)
5. Relief valve
Rated flow: 401/min
Adjustment pressure scope: 16-32 MPa
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
Design.

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.
