Protect Your Belt Conveyors with Voith Fluid Couplings.

They have been in service for decades under the toughest conditions and have proven themselves worldwide. Voith fluid couplings protect belt conveyors and drive components by providing smooth acceleration and torque control allowing for frequent loaded starts with the least amount of stress on the drive and belt. In multi-motor drives they ensure precise load distribution. Result: fewer downtimes and the service life of the belt and the drive components are increased. The latest product innovation is the Voith TurboBelt 780 TPXL. Tel: +27 11 418 4000 info.vtza@voith.com www.rsa.voithturbo.com
