Product Description

hard rock pneumatic water well drill machine for deep wells

HQZ220L Pneumatic Drill Rig

* HQZ series water well drilling rig is a lightweight, efficient and multifunctional drilling equipment , it is mainly applicable
to industrial and civil drilling, geothermal drilling, has the advantages of compact structure, fast advancing, mobile and
flexible wide application region etc.. It is especially suitable for water intake in mountainous and rocky strata.

* The rig can create drilling jobs in different strata, borehole diameter can up to 245-294mm. The rig with hydraulic technology, supporting high torque hydraulic motor rotation and large bore hydraulic cylinder push, the multi cylinder engine of famous factory provides power for the hydraulic system, two stage air filter, air compressor air intake design, prolong the service life of diesel engine. Special pump set design is convenient for maintenance and reduce the cost of maintenance. Centralized control of the hydraulic control table, convenient operation.

* 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 to ensure the accuracy and reliability of the positioning and centering. The hoisting mechanism is convenient for hoisting of drill pipe and impactor, so as to reduce the labor intensity.

* This machine can be applied to various strata, used in water well engineering, geothermal well, anchor pile hole and so on, and can be used with follow-pipe drilling. It has the advantages of whole machine hydraulic control, automatic loading and unloading drill pipe, crawler type chassis, large horsepower diesel engine, four hydraulic support leg balance, stronger
terrain application ability and so on.
