  • JTPB Mining Winder

    This product is suitable for lifting coal, materials, lifting personnel and equipment for derailing materials in coal mine shafts or inclined shafts. It can also be used for other traction transportation. working principle When the main motor is started, the motor rotor transmits power to the high-speed shaft of the reducer through the elastic coupling, and after being decelerated by the reducer, the passive shaft of the reducer is transmitted to the spindle device through the gear coupling, if Constantly changing the steering of the motor, the reel can be wound or loosened, and the lifting container can be moved up and down periodically in the wellbore. Product model representation: The method of lifting the winch model shall be in accordance with the provisions of MT/T 154.8-1996. 1）, the minimum safety factor of the wire rope meets the following requirements: 1. 9 times for lifting personnel; 2. Lifting personnel and materials (9 times for lifting personnel, 9 times for mixing and lifting, 7.5 times for lifting materials); 3. Specially designed for lifting materials 6.5 times. 2）. The ratio of the diameter of the drum of the uphole mine hoist to the diameter of the wire rope shall not be less than 80 times; the ratio of the diameter of the drum of the underground mine hoist to the diameter of the wire rope shall not be less than 60 times. 3）. The number of layers of wire rope wound on the reel shall comply with the following requirements: 1. Lifting personnel or lifting personnel and materials in the vertical shaft, 1 layer; specially designed for lifting materials, 2 layers; 2. Lifting personnel and materials in the inclined roadway, 2 layers; 3 layers for lifting materials; 3. Lifting personnel and materials during construction, 2 layers.
