The return column winch adopts a spherical worm gear pair transmission, which has a compact structure and small dimensions, and can be used downhole as a whole. The winch has a symmetrical structure, elongated shape, and a sled-shaped base. It is stable and flexible in self-moving underground and has a low center of gravity. , the base has good rigidity and can be used to support the pillars and install ground anchors, so it is easy to install and operates smoothly, safely and reliably.
The back-column winch, also known as the slow-speed winch, is used for the back-column and topping of the underground coal mining face in coal mines. Due to its low height and light weight, it is especially suitable for mining working faces in thin coal seams and steeply inclined coal seams, as well as for recovering metal pillars sunk into the floor or buried under gangue in various coal mining working faces. With the improvement of mechanized coal mining, it is increasingly used in mechanized coal mining working faces for installation, recovery, traction, and spare parts of various equipment and spare parts.
The return column winch has explosion-proof performance and is mainly used for lifting the return column in underground coal mines. It is especially suitable for thin coal seams and inclined coal mining working faces, as well as for recovering metal pillars that have sunk into the bottom plate or are stuck by gangue on various coal mining working faces. It can also be used for auxiliary traction work such as moving the flow trough and moving the belt conveyor head.
