This type winch adopt "tooth - al" driving system and transmission characteristics of the biaxial multistage, realized the fast and slow speed of two, its slow can replace existing prop-pulling hoist winch, and a slow its fast can replace the existing scheduling winch and winch.

On the structure characteristics, not only to achieve the small structure, the characteristics of big tension, also realized the elongated symmetric structure characteristics, suitable for the coal mine narrow work space, convenient operation. It overcome the current slow, prop-pulling hoist series of low transmission efficiency, short service life, low efficiency, also overcomes the series winch, scheduling, transportation of traction force is small, wide type structure, etc.
