High speed and conventional / Tramway
Tensionning devices
Due to the elongation of contact and messenger wires caused by variations in atmospheric temperature, compensation devices are necessary in order to assure a constant mechanical tension on the lines.
- Concentric toothed pulley systems. Compensation ratios available 1:3 and 1:5.
- Complete solution including tailored supports to pole, anchors and counterweights.
- Multiple pulley system,. Compensation ratios available 1:3, 1.4 and 1:5.
- Low and easy maintenance even in adverse environments.
- Spring tensioning devices are the main solution at tramway systems.
- Tensile load working ranges 1-3, 6-10 and 10-15kN.
- Compensated elongations depending on project necessities.
