EXCAVATOR DRILL
Dopro Excavatot Drill Advantages:
Multi-purpose: do not change the performance of the original
machine, 1 hour can be realized drilling, excavator exchange.
Simple operation: in the excavator cab, the operator can
operate after simple training, without professional personnel.
Fast speed: The hydraulic drill in the hardness of 5.6 degrees
above the rock drilling speed can reach a minute 2-4 meters, is 8
to 10 times of the pneumaticequipment
Flexibilitly: The excavator rock drill fully combines the walking
convenience of the excavator and the drilling speed and other
advantages of the drill, can be suitable for complex conditions of
drilling operations.
Compared with the traditionall drilling machine, it has the
following advantages :
1 It greatly improves the construction environment, reduces the
labor intensity and labor cost
2, the construction efficiency is improved several times.
3. Reduce environmental pollution and reduce energy
consumption.
4. The excavator rock drill has strong walking abilitly and large
operating range.
