Power cable management for mobile construction machine

An Austrian company active in the construction business is seeking an innovative solution for the electric cable management for mobile construction machines (~25 tons). I. PROBLEM DESCRIPTION Conventional diesel powered engines are loud. By using low-noise solutions the construction site could be prepared already very early in the morning without disturbing residents. Currently the mobile electric construction machines have to be connected to the electrical power supply via a 5 phase high voltage cable (3x400V 1xneutral wire 1xearth wire). At the present the electric cable is provided exernally. In future the electric cable and the cable management should be an integral part of the machines. Once the machine is on-site the cable should be removed from the machine and be connected to the local power supply. The main challenging problems to be adressed are: 1. Cable management: - For connection of these heavy weight and stiff cables to the electrical power supply a special equipment (cable management) is needed to move the cables since they can not be moved by manpower. - For machine transport an efficient/compact storage solution of the cable and its cable management solution has to be implemented. 2. Cable protection - To ensure durability of the cables they have to be protected against rough conditions on site as they are exposed to sun, rain, frost or dirt and other heavy vehicles may pass over the cables. 3. Machine mobility - To ensure mobility of the machines it has to be possible to drag along the cables during the movement of the machine. II. COOPERATION SOUGHT - The Austrian company is looking for existing solutions which can easily be adapted for the described purpose. In case of IP protection a license agreement is sought, otherwise a commercial agreement with technical assistance is sought. - Alternatively the Austrian company is ready for collaborative R%26D activities. In this case a research or a technical cooperation agreement is sought.
