WINDER CONTROLS Australia have developed a system for standard Friction Winders, that provides personnel recovery in the event of a power loss or a winder control system malfunction.

The Pony Drive System is capable of bidirectional travel, guaranteeing a fast, reliable and safe method of evacuation. It relies on the drum, brake calipers and piping to the calipers to be fully functional. Operation of all other winder components and system is assumed to be inoperable. When required, the Pony Drive System is engaged by an internal tooth ring gear, fixed to an emergency drive. Once the direction of travel is specified by the operator, the lowering or raising of the conveyance will begin at a controlled rate of between 0.25 m/s and 0.5 m/s.
