Product DescriptionGY-300A is a core drilling rig for medium and
shallow hole. It is applied not only to alloy and diamond core
drilling with different calibers but also can be used for
geological prospecting works, fluid ore drilling in surface layer
and shot holes and drilling vent holes, drilling in hydrology,
water wells and large bores. It has been widely used in such areas
as road and railway construction, water resources and hydropower,
and architecture.Product Features1. Large torque, 8 rotation speeds
in an appropriate range, large drilling capability.2.The rig has
two reverse rotation speeds to facilitate drilling and handle
drilling problems.3. Long feeding distance(600mm), higher drilling
efficiency, lower probability of drilling problems.4. Hydraulic pin
chuck, able to reliably lock the Kelly bar without tiny damage to
it.5. The rig has large drilling capability with small size and
light weight.6. Mineral exploration, water well boring, pile hole
boring.Note: GY-300T is a model developed on the basis of GY-300A,
which is integrated with a hydraulic tower system. The hydraulic
tower can be set at different angles for incline drilling.Product
