TENSOREX C+ is significantly more compact than conventional tensioning devices, and can be fitted in about an hour.
TENSOREX C+ facts
How It Works
By means of a support cable, TENSOREX C+ exerts a constant tension on the contact wire, regardless of any changes in length due to temperature. The special spiral spring is firmly connected to two cams on the same shaft. The degree of rotation of the shaft results in a linear variable torque/moment, which is compensated for by the combination with the variable radius of the cam. This produces a constant pulling force over the entire device working range.
F – Contact wire -> Force on contact line
M – Spring -> Torque/moment applied by spring
r – Pulley -> Radius of cam (variable)
l – Work -> Device working range correspond to variable pulley profile length
