2JK Mining Hoist Winch

The 2JK mining hoisting winch features a double-drum structure and is primarily used in small and medium-sized metal and non-metal mines. It is suitable for hoisting ore in underground vertical and inclined shafts, removing waste rock, and lifting personnel and equipment. It can also be used for transporting materials on open-pit slopes or trenches. It excels in complex working conditions requiring simultaneous hoisting and lowering operations and can operate stably in dusty, high-humidity environments.
