GY-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.
1. 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.
