      Application:  Pull Lift Chain Kone Hoist Hoist with Electric Hoist Switch  The products of this series are used to lift materials, equipments and people in coal mine ,iron mine, metal mine and non metal mine inclined roadway and small shaft.     JKMD working principle:         The closed rope winded the drum which carrying the container in the central. When the drum rotated by motor, lifting and lowering of the container via the friction between the rope and drum. The Machine speed adjusted via electric drive. And the braking of disc brake via hydraulic and electric system.   Position indicator system shows the depth of the container.  The control  system integrating the motor, electric and hydraulic pressure supervises  and protects the whole equipment through a variety of sensors and control elements.  Internal and external information transmission is carried out by the computer and the  internet technology.          ABOUT US   Hebi wanfeng Mining Machinery Manufacturing Co.,ltd is the biggest and strongest enterprise in the local place of henan province.
