We'll get you high up.... .... and safely down again!
portable passenger elevator Cumulus Alpha

The portable passenger rope elevator - WolKi Cumulus Alpha - was developed in cooperation with the company Ortner Kofler GmbH & Co Kg, who are specialists in scaffold-free height working.

The design is optimized to provide a high level of toughness, usability, mobility and extensibility

(removable bucket and carabiner holders). Furthermore the rope elevator can be used for facade cleaning and in the near future to maintain wind turbines (independent power-source is essential).
