AFY series raise boring machine is a highly efficient drilling device researched and designed to improve
the back ward technologies of hanging cage and manual construction widely applied in winze construction.
Raise boring machine is widely used in such sectors as coal mine, metallurgy, water conservancy and
hydropower for construction of winze, ventilation shaft, cable pit, drain hole, waste stone leaking shaft.
Different types of boring machines can be selected by the customer according to drilling diameter and depth.
AFY series raise boring machine adopts fully hydraulic drive. It is a novel model with compact structure
and high mechanization. It is convenient to transport, easy to operate, thus able to work under
explosion-proof required environment. With strong adaptability, the boring machine has the
characteristics of safe construction under different geologic conditions, high bore quality and low
construction cost. Using raise boring machine is a revolution in shaft building process.
