JH-20 Mining Pulling Winch for Prop, adopting the spherical worm gear pair drive, are compact and small and can be completely down the mine;
prop pulling winches are symmetrically and rectangle arranged with the sledge-shaped chassis, smooth and flexible for underground self-moving;
JH-20 Mining Pulling Winch is for both prop pulling and placing ground anchor due to low center of gravity and good features of chassis, so they are easy to install, smooth to operate, and safe and reliable.
