60 years maintenance-free (no lubrication, no replacement of wires)!
This Austrian development optimises both, the quality of the catenary chain as well as the life-cycle-costs of weight tensioning. Reduced friction takes effect positively on the accuracy, adjustability minimises the wear of the wire, optimum material combination spares the use of lubricants. In case of a wire-snap, the safety wheel locks and prevents the weight from falling down onto the tracks or a train-platform.
Longest life expectancy at maintenance-free operation and highest accuracy makes this auto-tensioning device one of the best systems on the market! This automatic tensioning device is the first choice for future orientated railways with highest requirements.
