Complaint
Fully hydraulic boring trolley, hydraulic direct control, composite coordinate system parallel positioning drill boom, to meet the different needs of customers;
The tunnel drill consists of 5 modules:
1. Thruster
2. Control system
3. Rock drill
4. Complex coordinate system drill arm
5. chassis
1. Thruster:
Heavy duty aluminum alloy propulsion beam with high bending and torsion strength and long service life.
The surface of the propulsion beam is covered with stainless steel skin, and the moving parts are covered with teflon wear-resistant gasket to improve the service life.
2. Control system:
Hydraulic drilling control system, with automatic opening, no lubrication no water no impact, rotary pressure automatic control push, push pressure automatic control impact function.
The engine automatically ADAPTS to decrease speed and increase output torque without flame-out when overloading and climbing.
Unique hole bottom slag flushing function, drilling clean, easy charging.
3. Rock drill:
rock drill is equipped with double buffering system to prolong the service life of drilling tools.
The pressure oil film protects and lubricates the joint interface to reduce the internal wear of the drill.
4. Complex coordinate system drill arm:
The double triangular suspension support drill arm ensures accurate hydraulic parallel hold in all directions.
5. chassis:
Solid articulated heavy-duty chassis, four-wheel drive.
Double circuit pedal brake and emergency stop brake, Under the premise that one or even two pipelines are damaged, it can also be safely brake.
