Portable core drilling rig
mechanical equipment
The portable core drilling rig has a compact and simple structure,
and all components of the drilling rig, including the drill rod,
can be transported by one 5-ton truck.
Lightweight, flexible, safe, and reliable portable core drilling
machines can be transported manually or on pack horses through
small paths in areas with inconvenient transportation conditions,
saving customers a lot of investment in building temporary roads,
shortening exploration periods, saving labor, and reducing handling
risks and costs. The drilling rig is driven by hydraulic pressure,
modular, structurally safe and reliable, easy to operate, reduces
labor intensity, and is more user-friendly; The airport uses a 12V
DC power supply for safer electricity usage; When relocating the
machine, it is easy to disassemble and install, making it easy to
move the drilling rig. The maximum weight of a single component in
the drilling rig shall not exceed 180 kilograms, with a total
weight of 1160 kilograms.
No drilling tower design for structural safety
No need for tower operation, reducing the safety risks of tower
operation and increasing the safety factor of operation.
Compact drilling rig is beneficial for environmental protection
Especially suitable for construction in mountainous terrain with
large cutting environments or in forest areas, the installation of
drilling rigs only requires 4 x 4 meters or even smaller flat sites
for work. There is no need to build temporary transportation roads,
which solves the problem of extensive excavation of earth and stone
or cutting down of trees during the leveling of machinery, reduces
the damage to vegetation and the environment, and lowers the
compensation amount for temporary leasing of drilling land, thus
maximizing the protection of the construction site and surrounding
environment.
Energy saving, consumption reducing, high-quality and efficient
drilling rig allows diamond drill bits to have higher rotation
speed and drilling tools to cut rocks more smoothly, greatly
shortening exploration period and reducing costs. The drilling rig
is not only fast, but also has an average fuel consumption of 400
liters per 100 meters, and the core recovery rate can reach over
95%.
