For a project in Thailand, the concrete spreader could only reach its washing station along a branch line, whereby the hopper travels 13.5 metres in the working chamber and then another 55 metres to the cleaning point once or twice a day. Over these distances EBAWE needed an energy supply solution that would endure the harsh working environment of the concrete production facility while, at the same time, be completely reliable.
The EBAWE engineers solved this problem by using an igus e-chain in the main working chamber that is supported by a guide trough. For the long branch line and travel to the cleaning point, a second system comprising another e-chain and guide trough is used. The energy chain in the shorter mobile channel is locked, and the chain moves together with the channel on wheels above the lower system until the chain has been completely extended. The remaining distance to the cleaning point is then covered by the upper system again.
The automated solution for changing from moving in day-to-day operation and moving to the cleaning point works reliably and will be used again where a similar problem has to be solved.
Don’t forget, applications for this year’s vector awards can be submitted online, by filling in a simple form with a design brief and description of the energy chain application. Supporting photos and videos can also be uploaded.
