Multi-rope friction hoists are widely used in mining, metallurgy, construction and other fields.It is a key equipment for mine hoisting, which can effectively and safely lift various materials and personnel.
In mines, it undertakes the important task of lifting ore, coal, etc. from underground to the ground; in the metallurgical industry, it is used to lift high-temperature liquid metals such as molten steel and molten iron; on construction sites, it can help lift construction materials and improve construction efficiency. The multi-rope friction hoist provides a strong guarantee for the production and operation of many industries with its stable and reliable performance.
Advantages of multi-rope friction hoist:
(1) The lifting container and the load are jointly borne by a plurality of wire ropes, compared with the single-rope winding lifting equipment, the diameter of the lifting wire rope is smaller, the diameter of the main wheel and the size of the whole machine are reduced accordingly, the quality of the equipment is lighter, and it is suitable for the lifting of deep wells and large equipment, and can meet the development needs of the increasing expansion of the mine and the extension of the deep part.
(2) Because the lifting container is suspended on a plurality of wire ropes at the same time, these wire ropes generally will not be pulled off at the same time (the wire rope slippage phenomenon will occur when the tension is too large), so the fall arrester can not be set.
(3) The multi-rope friction hoisting system is generally a balanced hoisting system, and the diameter of the leading wheel is small, the inertia and torque of the system are small, and the motor power and power consumption are small.
(4) The number of lifting wire ropes is generally even, and the left and right twist directions account for half each, which can cancel the loose twist torque in the operation of the wire rope with each other, reduce the running resistance of the lifting container to the tank road, and prolong the service life of the tank road and the tank lug.
(5) When the tower type lifting is adopted, the friction wheel hoist is installed on the well tower, which reduces the floor space of the hoist.
