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 time meter. 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.

Main Components
Power unit
Machine body
Control panel
Rotation unit
Rod holder
Slurry Pump
Surface mast hydraulic type

More Features of GP90-3 hydraulic diamond drill rig:
Main Duplex hydraulic pump direct connection with power motor without gear box between which enhanced the drive power and efficiency significantly.

High quality drive chain with heavy duty configured.
 
High quality Jaw made by ourselves.

High quality oil seals.

High quality shape-unchangeable imported spring.


High quality oil resistant, high temperature resistant and high pressure resistant rubber seal O ring..

High quality anti-loose gasket

Considerate move and deliver tools.
