The Crawler Multi Function Drilling Rig ZML161 is a compact full hydraulic crawler mounted engineering drilling rig compliant with ISO9001 construction.
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.
