French cable-driven lift systems manufacturer Poma and cable maintenance specialist Comag have used Enerpac strand jack technology to streamline aerial cable maintenance operations on the 3 km-long Téléo cable car in Toulouse, France.
The longest urban cable car ever built in France, the Téléo cable car route connects Paul Sabatier University to the Oncopole Institute via the Rangueil Hospital, in only 10 minutes. It uses four carrier cables, with two carrier cables per track, along with a looped traction cable. The cabins run on these cables, akin to a railway track.
Aiming to reduce cable tensioning times, Poma left the cable sliders in position by pulling two track ropes at the same time. It did this by attaching the two track ropes to a lifting beam which was then attached to an Enerpac HSL 20006 strand jack. When stroking the strand jack, the cables can be tensioned up to a maximum of 240 tonnes in incremental steps of 480 mm.
The cables were slackened at Paul Sabatier station and the track ropes tensioned by the strand jack, which was positioned at the Oncopole-Lise Enjalbert terminus, 3 km away – at the end of the cable car run. During the tensioning operation, 30 m of cable were moved to regain the correct cable position.
“Pulling both cables at the same time, in perfect synchronisation, was a major objective of the operation, until now we’ve relied on a pulling winch and hauling system for each cable, a time-consuming process,” said David Blanchet, project manager, Comag. “The Enerpac strand jack was the right choice for us thanks to its operating speed, ease of use and small size, which allowed us to place it between the two track ropes in a horizontal frame.”
Poma developed the new system in collaboration with Comag.
In September 2025, Poland’s MS Industry deployed Enerpac gantries to move a 1,100-tonne press in Germany.
