TENSOREX C+

The TENSOREX C+ is an innovative patented automatic spring tensioner that applies a constant tensile force to the contact wire and/or carrying cable of railway and tramway systems. This is to compensate for any variation in length, due to temperature influences during seasons. Compared to wheel tensioning with counterweight, the TENSOREX C+ is very compact (all measurements) thanks to the use of coil springs instead of weights.

  • For railways and tramways
  • Best solution for gantries, tunnels and platforms where safety is important
  • Inner-city installations where low visual impact is required

Facts

  • Sold worldwide
  • Patented system
  • Compensation length: 450-1100 mm
  • Line tension force: 7.5-40 kN
Functioning

Functioning

The TENSOREX C+ has benefits in terms of use, installation, shipping, storage and reduces overall costs. The TENSOREX C+ can be regarded as a spring that exerts a constant force on the contact wire at any variation of its length due to temperature influences. A coil spring (or springs) and two pulleys with variable radii are jointly assembled and operating on the same bearing shaft. The variation of moment exerted by the spring during its rotation is compensated by the variable radius of the pulleys, which are connected to a bearing shaft and stainless steel cables leading to the contact wire and/or support cable.

Benefits

  • Reliable: each TENSOREX C+ is tested before being shipped to the customer
  • Compact design: easy handling and transport; the solution for installations
  • Quick installation: ready to install, no assembly required, no weights to install, time saved during installation
  • No tension weights required: vandal-proof, free space around mast, no obstructions
  • Maintenance-free
  • High precision: constant force over the entire range, fast and accurate, very small traction force hysteresis
  • Purely mechanical system: requires no additional power supply, no influences from temperature changes
  • Reduced risk of vandalism / theft
  • Aesthetically pleasing
  • Suitable for use in tunnels and areas with limited space
  • Various mounting solutions available for all kinds of applications
  • Reusable in case of wire breakage
