ZML160 Anchor drilling machine multifunctional crawler type drilling rig
It is widely used in fields such as construction, highways,
railways, water conservancy, electric power, tunnels, foundation
pits, slopes, and military engineering.
Suitable for rock drilling in drift, egg, gravel layers, and layers
covered by fractured and strongly weathered rocks, it can
particularly demonstrate its efficient and stable performance. It
can quickly and efficiently drill through complex formations and
has broad application prospects in various geotechnical anchoring
projects.

Main features
Dynamic system
The whole machine can replace different power heads(DTH, top drive,
coring) according to construction needs, making construction more
convenient, reducing costs, and doubling production;
Rotating arm structure
By adopting a rotary arm structure, the operating range after one
positioning is greatly increased. The drilling arm can rotate about
360 °, achieving any angle construction;
Control costs
By using pilot valves and variable piston pumps with load feedback
systems, it has the functions of power protection and pressure
cut-off. While effectively adapting to the total flow demand of
various executing components, it achieves the best power matching
under different working conditions and maximizes energy
conservation;
Security measures
When drilling, the wind and water linkage system is used to reduce
the large amount of dust generated during tunnel construction.
While drilling, the crushed stones are washed out of the hole
through high-pressure water, reducing the problem of sticking
during drilling, achieving the goal of rapid drilling, improving
work efficiency, and reducing construction costs;
Pipe shed construction
Both single rod drilling and drilling with casing can be used. When
the geological situation is complex and there is collapse, the
casing construction method can be adopted, which means the outer
casing and inner drill rod drill to the required depth at the same
time. Firstly pull out the inner rod, then pull in the steel pipe,
finally pull out the outer casing;
Emergency rescue
During the construction process, in case of danger, geological
exploration, geological improvement, and support operations in the
danger zone can be quickly completed. If the underground space is
obstructed by collapse, casing operations can be used to quickly
transport air, water, and other rescue materials to the trapped
personnel;
