The Crawler Multi Function Drilling Rig ZML161 is a compact full hydraulic crawler mounted engineering drilling rig compliant with ISO9001 construction machinery standards.
The Crawler Multi Function Drilling Rig ZML161 is a compact full hydraulic crawler mounted engineering drilling rig compliant with ISO9001 construction machinery standards. It is specially developed for tunnel advance support, pipe shed drilling, anchor bolt drilling, grouting hole construction, slope reinforcement and shallow geotechnical investigation projects. Equipped with 360 deg rotary upper platform, high performance hydraulic power head and heavy duty crawler undercarriage, this rig supports DTH air percussion drilling, rotary mud drilling and grouting construction processes. It can perform horizontal, inclined and vertical multi angle drilling operations, adapting to fractured rock, broken surrounding rock, gravel soil composite strata in tunnel and slope sites. Integrated wired handle plus wireless remote control dual operation mode greatly improves operational flexibility inside narrow tunnel spaces. With compact transport dimension, low ground pressure crawler design and powerful cross country mobility, ZML161 is an ideal multi purpose geotechnical drilling solution for tunnel contractors, slope stabilization engineering teams and infrastructure construction customers worldwide.
The upper working platform can realize 360 degree free rotation relative to crawler chassis. Operators can adjust drilling azimuth without relocating the whole machine, greatly improving working efficiency for dense multi hole construction in narrow tunnel and slope sites.
Support both on board handle operation and wireless remote control operation. Remote control allows operators to keep away from dangerous rock fall risk zones inside tunnels; wired handle serves as backup control mode to guarantee construction continuity under complex signal interference environment.
Heavy load drilling boom features large swing and luffing angle range. Built in 1000 mm feed compensation stroke absorbs position deviation during drilling, keeps stable drill bit contact with working face, and reduces auxiliary positioning time for each borehole.
Optimized wide track shoe design achieves low ground pressure performance, preventing sinking on muddy tunnel entrance ground and loose slope covering layer. Independent hydraulic travel motors realize flexible steering and short distance moving inside limited space construction zones.
Hydraulic system runs at 25 MPa rated working pressure. Reasonable flow distribution matches power head rotation, boom action and crawler travelling simultaneously. Multi stage over pressure protection and pipeline burst resistance protection enhance safety under impact load tunnel construction conditions.
The whole machine adopts compact integrated layout to adapt to narrow tunnel transportation and operation space. Main wearing parts and hydraulic components adopt universal industrial specifications for easy spare parts procurement and rapid field repair.

Tunnel headings, cut slopes and mine roadways share one constraint: confined space, broken surrounding rock, with holes going horizontal, inclined or vertical rather than straight down. Does a conventional vertical drill solve that? Usually not — which is the envelope the ZML161 crawler multi-function drilling rig was engineered around. Its 360° rotating upper platform swings the drill boom without relocating the carrier, the 8000 N·m power head covers 90-300 mm holes at 20-150 m for pipe-shed, anchor-bolt and grouting work, and the 85 kN feed / 85 kN lift with a 1000 mm compensation stroke keeps the bit pressed to the tunnel face. At 10500 kg and a 7100 x 2450 mm shipping length, that is the clearance you must verify against your tunnel cross-section before ordering.
When you send a ZML161 inquiry, the configuration hinges on hole geometry rather than depth: the azimuth and inclination range of the planned bores, the pipe-shed or anchor-hole diameter and length, and the drill string you already run — 76 mm or 89 mm rods at 1.5-3.0 m. State whether the work is DTH air percussion in hard broken rock or mud rotary in gravel soil, and whether the site needs wireless control; the dual wired-handle and radio setup lets operators stand outside the fall line in narrow headings. The -20 °C to +50 °C window and 25 MPa circuit are baseline; electric-drive packages suit restricted tunnel ventilation.
Once your hole plan, tunnel clearance drawings and ground conditions reach our engineers, expect a benchmark quotation back within 48 hours. Every unit is configured around the power-head torque state, control mode and tooling package your contracting schedule demands, so we quote to the project rather than publishing a machine price.
Adjust power head torque speed parameters for extra hard rock; match dedicated DTH hammer and drill string package for large diameter pipe shed hole construction.
Optional full electric drive or hybrid power configuration for underground tunnel sites with strict exhaust emission restriction; match explosion proof electrical components for mine tunnel working environment.
Optional widened anti sink crawler tracks for muddy and soft ground construction sites; optimize overall dimension for extra narrow tunnel passage conditions.
Auxiliary grouting manifold assembly, drilling depth real time counting module and enhanced wireless remote control communication module are optional for complex construction site demands.
Provide personalized painting, exclusive brand logo marking, complete drilling tool kit, on site commissioning training and 24 hour full process after sales technical support.
