Introduce:
GY-300A is a core-drilling rig for middle and shallow hole. It applies not only to alloy and diamond core drilling with different calibers but also can be used for geological prospecting works, drilling of fluid mineral in superficial layer and shot holes and ventilation holes drilling, drilling on hydrology, water wells and big calibers. It has been widely used on areas such as road and railway construction, water resources and hydropower and architecture.
