Winches have the following characteristics: high versatility, compact structure, small volume, light weight, heavy lifting capacity, and convenient use and transfer. They are widely used in material lifting or towing in buildings, water conservancy engineering, forestry, mines, docks, and other fields. They can also be used as matching equipment for modern electric control automatic operation lines. There are 0.5-350 tons, divided into two types: fast and slow. Among them, those weighing over 20 tons are large tonnage winches. Winches can be used alone or as components of machinery such as lifting, road construction, and mine hoisting. They are widely used due to their simple operation, large rope winding capacity, and convenient relocation. The main technical indicators of the winch include rated load, supported load, rope speed, rope capacity, etc.
The main purpose of the winch is to serve as a lifting equipment, used for lifting, sinking, and suspending (lifting) sinking equipment and facilities in mines, that is, lifting ore, waste (gangue), lifting personnel, lowering materials, tools, and equipment along the wellbore; Secondly, as a transportation equipment, it is used for underground scheduling and transportation of ore (ore trucks), mining site raking (slag) or filling, removing pillars, etc.
