RBM Raise Bore Drilling Rig Machine for coal mine exploration with
max raise depth 400m
Wide range of applications:
Mechanized shaft construction will become increasingly important in
a wide range of applications thanks to this innovative technology.
The Raise Boring Rig creates shafts for the transport of muck or
ores, conveyor shafts, supply shafts for energy, water and air, or
headrace shafts for hydropower plants - safely, precisely and
cost-effectively.
STD-R80 is a low profile and lightweight raise boring machine for
holes ranging from 2 to 2.5m in diameter. It is proven on the
jobsite with best performance
Features
1.Multipurpose drilling:
STD-R80 rig offers unsurpassed versatility. It can be used for
conventional raiseboring as well as
down reaming and upward boxhole boring.
2.Smart power:
To boost safety and productivity, the derrick features a
full-automated drive head wrench and a
hydraulically powered, remote-controlled worktable wrench to
minimize heavy lifting.
3.Total control: From a remote work station, the rig operator can easily adjust
drilling speed and torque
to optimally suit the current work conditions.
4.Main components:Our large number of patented technology and numbers of
international well-known components (such as electric parts,
hydraulic parts, transmission parts) are included in the RBM.
Compared with same kinds of products, ours are more reliable and
more durable.
5.Two drilling modes and three operation modes:
The control system supports two drilling modes(high accuracy
drilling mode and fast speed drilling mode) and three operation
modes(manual operation, wireless operation and wired operation).The
user can select drilling mode according to accuracy requirement and
geological conditions and select operation mode according to
operating position and the actual situation.
