Mine auxiliary hoist ЛВ25 is designed for hoisting equipment and materials in incline workings up to 30o of coal mines of any category in gas or dust. The specificity of the design is availability of a friction coupling which allows speed controlling smoothly. The hoist is characterized by a large tractive effort, high speed and rope capacity at a relatively small motor capacity.
