Fully Hydraulic Tunneling Jumbos Tunnel rock anchoring drill rig
used for tunnel support
DW551 is a small and medium-sized hydraulic rock drilling equipment
independently researched, developed, and manufactured by our
company. It is mainly suitable for excavation and construction
operations in tunnels, mining, hydropower, railway, highway, and
other fields; It adopts an advanced fully hydraulic rock drilling
system, equipped with an anti jamming device. It has a compact
structure, and the drilling arm is extendable. It can perform multi
angle and multi-directional drilling positioning relatively
parallel to the working section. The climbing ability is ≤15%, the
walking speed can reach 12km/h, moving speed is fast. It is an
excellent underground mining and tunnel excavation mechanized
drilling equipment.

Product advantage
The advantages of a tunnel anchor bolt jumbo (or cart) include:
Adaptability to complex geological conditions: Tunnel anchor bolt
jumbos possess strong thrust and torsional resistance capabilities,
enabling them to adapt to various geological conditions during
anchor bolt installation. Whether it is soft soil, rock formations,
or high-risk strata, the jumbo can perform stable construction
operations.
Wide construction scope
The drilling arm can rotate 360°during propulsion, and the drilling
arm with translational propulsion can drill holes in all
directions, no dead angle;
High security
It has excellent power system, greatly improves the construction
environment, and achieves green construction;
High work efficiency
The high-strength chain, combined with a high torque hydraulic
motor, provides reliable pushing and pulling support during the
drilling process; Accurate drilling reduces the occurrence of
leakage and deviation during construction, significantly improving
the blasting effect;
Operating platform
Ensure that the operator has a good field of vision, simple and
convenient hydraulic control console, allowing the operator to
operate easier and improve work efficiency;
