JH-5 prop pulling winch using spherical worm drive, with compact structure, small size, the machine can go down, symmetrical structure, elongated strip, sled shape base, self-moving smoothly in the underground; focus low, base rigidity, both hitting top prop, but also install the anchor, therefore, so easy installation, smooth operation, safe and reliable.
Prop pulling winch is also known as slow winch ,which is for the coal mine caving coal face back purposes. Because of its low height and light weight, especially for thin coal seams and steep seam mining face, and a variety of floor or sink into the coalface recycling waste rock buried beneath the metal pillar. With the improvement in the level of mechanized coal mining, which are increasingly being used in mechanized coal face, as the installation of equipment and spare parts of recovering and dragging.
JH-5 prop pulling winch with explosion-proof properties are mainly for the coal mine back caving purposes. Especially suitable for thin seam coal face and tilt, as well as in a variety of work surface coal gangue card recovery sink or floor junction metal pillar. Also be used as advection tank top auxiliary traction belt conveyor moving work.
