The XDQ-1200 full hydraulic core drilling rig has modular design,
single module is not more than 200 kg, easy to move. This core
drilling rig also has constant pressure drilling control system
(patented technology), automatically set constant pressure
drilling, improve drilling efficiency and ensure the quality of the
hole.It's powerful dynamic parameter display control system is our
patented technology.The main components of the hydraulic system
adopts imported brands. It is stable, reliable and has a long
service life.The power head adopts electro-hydraulic system, which
is equipped with a 4-speed gearbox and variable speed transmission
within a certain range. Adopting direct-acting and load feedback
fine-tuning variable hydraulic system, it is high efficiency, low
energy consumption that the power changes by the load, (this system
has been successfully applied on various series of drilling rigs in
our factory);Convenient control of drilling rig , The control
handles are reasonably arranged for flexible and convenient
operation. Powerful dynamic parameter display control system
(patented technology) can timely control the speed of engine, fuel
and water temperature, the pressure of hydraulic system, grouting
pump pressure, drilling depth, hole bottom pressure and various
parameters.
This drilling rig is specially designed for medium deep hole coring
drilling in mountainous and hilly areas, which is self-developed
according to the technological characteristics of rope coring after
compared advantages and disadvantages of the same equipment from
the different companies. It’s disassembled for easy movement. The
machine is mainly equipped with PDC and carbide drill bits. It can
be used in construction fields such as geology, survey, wells for
hydrology, shallow oil and gas, ect.
