Hand crank tensioner use worm gear and wire rope friction generated by the power to lift, in the steel of the wire are suspended at both ends of the lift container of the mine car, the use of friction between the wire and pad installed in the friction car, lifting materials and personnel equipment, its advantages are many, because a wire rope will not be wound in the motor ship, because the friction wheel does not have the capacity rope volume requirements, the width of the friction wheel than a single heavy winding type hoist The rolling of small, can adapt to the mine is deeper, the production of large mines, this is a multi-rope crane one of the advantages. As the mine car of multi-rope hoist is suspended by more than one wire rope, the diameter of the wire rope required is smaller than the single line under the same load, and the diameter of the friction wheel becomes smaller. Therefore, in the same upgrade tonnage, the multi-rope hoist covers a small area, saves cost, is simple to make, and is easier to install and transport. In case of accident, the possibility of multiple wires breaking at the same time is extremely small, so the tensioner manufacturer has high safety and does not need to install ropes on the mine car wire tensioner. The hoisting machine can be set up in the mine tower, and compared with the single rope hoisting machine, the area of the equipment is reduced relative to the configuration on the ground, and the building force is improved at the same time. Therefore, there is no need to install support feet to counteract the tensioning forces.
