1. The lifting container and load are shared by multiple steel wire ropes. Compared with a single rope winding lifting device, the diameter of the lifting steel wire rope is smaller, the diameter of the main wheel and the overall size are correspondingly reduced, and the equipment is lightweight. It is suitable for upgrading large equipment in deep mines and can meet the growing scale and deepening needs of mines.

2. Due to the fact that the lifting container is suspended on multiple steel wire ropes at the same time, these steel wire ropes generally do not pull at the same time (sliding of the steel wire ropes may occur when the tension is too high), so anti fall devices may not be provided.

3. The multi rope friction lifting system is generally a balanced lifting system, with small main wheel diameter, low system inertia and torque, and low motor power and power consumption.

4. The number of lifting ropes is generally uniform. Squatting down halfway can offset the loosening torque of the steel wire rope during operation, reduce the resistance of the lifting container to the oil tank, and extend the service life of cans and cans.

When the tower type is used for lifting, the friction wheel hoist is installed on the mast tower, reducing the footprint of the hoist.

6. Variable frequency control improves the control and protection performance of the winch, reduces equipment failure and maintenance rates, and has greater safety.

7. The control circuit of the mining winch adopts a frequency conversion speed regulation system, which has better energy-saving effect than the original series resistance speed regulation electronic control system.

In summary, mining hoisting winches have various advantages, which can meet different needs, improve safety and energy efficiency.
