The winner of this year’s golden vector is also the longest travel ever to be realised with plastic energy chains in the world. The travel is 615 metres, and was designed in a power station belonging to the utility company CEZ Group in the Czech Republic.
With this bucket wheel reclaimer, the setup can be moved in a circular movement by +/- 180°. This movement must also be able to be carried out by the energy chain. The use of plastic energy chains has resulted in a significant improvement in service life and fail-safeness.
In order to reduce the design space required and keep energy supply costs as low as possible, the Y- and Z-axes of this travelling column machine were to be realized using an energy chain. The travel is 0.7 metres on each axis, maximum travel speed 1.3 metres per second.
