What does crawler drill mean?
2, while the drilling speed is high, smooth, easy to operate safe, easy to achieve automation and instrumentation, high-speed small diameter drilling (such as diamond drilling) and high torque and low speed engineering drilling have a good adaptability
This type of drilling machine by high-voltage variable oil pump and variable oil motor to achieve stepless speed, can simplify the transmission mechanism, remove the gearbox, both to reduce the weight of the rig, but also make full use of power.
Full hydraulic drilling machine, also known as full hydraulic drilling rig, a hydraulic drive and control all the running parts of the rig.
But the drilling of the hydraulic components of the manufacturing process is more complex, the use of maintenance requirements are relatively high.
