Selected overhead line and railway projects and photos of our machines on customer sites worldwide.
From the world’s longest railway tunnel to a fjord crossing with a 5,500 m span: selected projects in which machines from Scheßlitz pulled lines and raised towers.

227 mTower height
On a Siemens site on the Elbe near Stade, the world’s tallest overhead line towers of their time were built: 227 m high and 1,000 t each. They were erected with a ZECK SPW 5 puller, which TÜV first had to approve as lifting equipment.
The project became a textbook example of raising a very tall, heavy tower with a puller.

57 kmTunnel length
In the Gotthard Base Tunnel, at 57 km the world’s longest railway tunnel, Kummler+Matter installed the catenary in 2013/14 with a ZECK BM 954 installation unit: 2 × 17 kN pulling force, six drum stands, 18.3 m long.
The result: catenary on 114 km in the two tunnel tubes and on 40 km of open line. The tunnel opened in 2016.
Overhead line · Norway · since 2008
5,500 mSpan
Since 2008, ZECK has been involved in fjord crossings in Norway, among others for Statnett, Valard and Dalekovod. Spans reach up to 5,500 m.
What makes them special: the machines come apart. A helicopter flies them in pieces onto the surrounding mountains, where they are reassembled.
ZECK stringing machines, tensioners and installation units on sites around the world – on overhead lines, on the railway and on ropeways.
