2020 underground Mining electric prop pulling drawing winch
Prop-pulling hoist also called slow winch, used for the coal mine coal mining working face prop-pulling caving. Because of its low height and light in weight, especially suitable for thin coal seam and steep coal seam mining face, the mining face and a variety of recycled into floor or by waste rock pressure of buried metal pillar. With the improvement of mechanized degree, it is increasingly widely used in mechanization mining face, the installation of various equipment and spare parts, recycling traction.
