ST450 Pneumatic Borewell Machine Advantages
The Drilling Rig Machine adopts a excavator crawler chassis and has
strong off-road performance. The independent module design allows
the drill to be mounted on the truck to increase its mobility.
Two speeds of rotating and advancing speed can meet the different
needs of soil and rock drilling Combined positioner, the
positioning disc can be adjusted and replaced according to
different types of drill pipe and impactor, so as toensure the
accuracy and reliability of the posoning and centering.The hoisting
mechanism is convenient for hoisting of drill pipe and impactor, so
as to reduce the labor intensity.
