Tensioning arrangement for pick=up wires or support cables - assigns movable rollers to fixing or junction points provided by support posts

摘要

To fixing or node points on the wire or cable there are associated movable rollers (12,13) via which the wire/cable (1,1') is offset and tensioned. The node or fixing points (K) are positionally fixed. The points (K) may be developed as triangular tongues (10,11) with deflection rollers (12,13), the opposing positions being established by holding cables (15,16) of defined length. These cables may pass to fixing points of the respective other wire or cable. Wheel and weight tensioners (5,6,8,8') may be provided at support masts (14,14'). ADVANTAGE - Allows tensioning up after fixing without increasing strength of supporting construction.
