Overhead line construction

Four conductors.
One pull.

On the tension side, the puller-tensioner keeps four conductors under even tension, so they run clear of the ground over the stringing blocks from tower to tower.

Origin

Family-run.
In the third generation.

Michael Zeck founded a metalworking business in Scheßlitz. It grew into a manufacturer of stringing technology: the first mobile winch-brake was built in 1972/73. Since 1993 the family business has worked in its own plant in Scheßlitz-Burgellern.

Company & history

  1. 1918

    Staff at the Oberend premises, Scheßlitz (post-war period, before 1953)

    Founded in Scheßlitz

    Michael Zeck, a trained metalworker, founds a metalworking business in Scheßlitz in late autumn: work for house and farm and the maintenance of machines. In 1924 he adds trade in agricultural machinery.

    First overhead line machine

    For FRANKENLUK, Fritz Zeck develops the first rope brake trailer for overhead line construction. The focus shifts from agricultural machinery to special-purpose machines for overhead lines — ZECK becomes a specialist.
