Prop pulling winch, also known as slow-speed winch, is used for pillar-returning and topping of coal mining face in underground coal mines.Because of its low height and light weight, it is especially suitable for thin coal seams and steeply inclined coal seam mining faces, as well as various coal mining faces to recover metal pillars sunk into the floor or buried by gangue.JH series explosion-proof prop pulling winches are mainly for underground prop pulling, transportation, placing ground anchor, and chute shifting.
JH series prop pulling winch adopted spherical worm gear pair drive, compact structure, are symmetrically and rectangle arranged with the sledge-shaped chassis, smooth and flexible for underground self-moving.zmwm02
