rope- and wire ascender

Important results from the project

The project has been designed to develop and produce a production-ready prototype of rope-winch for military purposes, maintenance of power lines or wind turbines. The project (the product) is unique in the rope transport and the lifting capacity. The project has included test of basic structures and a working prototype has been manufactured. In its construction, the product is relatively complex with an electrical/mechanical drive system with rugged control electronics. The project´s goals have been met and a partner for production has been appointed.

Expected long term effects

The project has resulted in production instructions for a first series. This has been made possible by constructing, testing and, where appropriate inventorying, of several functions such as rope transport, engine selection, engine control, mechanical braking system for safety and suitable energy source. During the project a working prototype has been developed. The product has also been designed for the best field function. The next step is a first production series for field tests. The outcome has matched expectations.

Approach and implementation

The project has been run in eight stages: Evaluation of rope transport and static tests of rope transport. Inventory of suitable electrical motors and suppliers as well as purchase of motor Inventory of mechanical braking systems as well as development and purchase from supplier Inventory of battery technology and supplier. Development of prototype drawings and production of one prototype. Tests of rope transport under dynamic conditions and with different configurations. Design Evaluation of tests and development of drawings and instructions for production.
