Installed on tramway lines, the spring tensioning device evolves. A new version is now available under part number JG1447/104.

Developed to meet the needs of a 150mm² contact wire, it ensures a mechanical tension between 1250 daN and 1750 daN for a temperature range from -20° to +50° and for a maximum canton of 120 m.

Equipped with an optional graduated ruler, the X dimension can be read easily from the ground. This rule is adaptable to all GALLAND spring tensioning device, even those already installed.

Its all stainless steel design, identical to the previous versions, will allow its use in high pollution environments. Installed on French networks for 30 years, our spring tensioning devices have proved their efficiency and longevity without any particular maintenance.
