Product DescriptionDFL-300 drilling machine is a kind of light and high efficient multi-functional water well drill rig with steel track, it is widely used in engineering construction for drilling wells,monitoring wells and ground-source heat pump air-conditioner,and also applied in hole blasting, bolting and anchor cable,etc.
The rig is a unique patented products:Top drive rotary power head and a hydraulic rotary disk rotating mechanism, hydraulic motors, hydraulic winch chain propulsion for deep hole drilling in institutions and
mast. The driller adopts the rotary drilling technology of reverse circulation drilling technology, mud,
compressed air DTH hammer drilling technology, can finish cover layer, sand gravel, sand, rock layer
stratum, large diameter deep hole construction. The drill, drill pipe rack lift unloading, leveling supporting legs, lifting, walking and other auxiliary movement by the hydraulic system, not only can improve the
working efficiency, and reduces the labor intensity of operators.
