First-time rope laying and subsequent rope changing still belong to the most hazardous tasks carried out in the shaft. To be able to speed up and carry out the complicated and often dangerous procedures safely and gently with today's multi-rope systems in deep mines, appropriate aids need to be employed.
These include in particular trailer-type or self-driving Friction Winders. The principle of the Friction Winder is based on the transmission of forces from the two drums to the rope by friction. These special systems can not only hinge ropes into the shafts, but can also pull them out.
The drive for the two friction drums is carried out by a powerful electric motor, supplying two planetary gear units that are synchronised on the drive side through a cardan shaft. All functions are controlled and monitored from the control station. Exchangeable drum linings enable Friction Winders to be used for various rope diameters; by angling the friction drums with appropriate linings, carefully laying of round-and-flat-section ropes is also possible.

- Can be used flexibly at different locations
- Easy inspection and maintenance
- Drum linings replaceable
- Use with various rope diameters
- Laying of round and flat-section ropes is possible
|Number of ropes||1 to 10|
