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.
