Strand jacks are used for lifting and lowering of heavy loads where conventional crane technology reaches its limits. The major advantage of strand lifting technology is that small and handy units are hydraulically generating high pulling forces. Several strand jacks are synchronously moving loads by means of a control unit and uniformly lifting them at various points. This is where the advantage as against conventional crane technology is considerably taking effect.
Strand jacks are also used for displacing heavy loads. Railway bridges are often erected near an existing structure in order to maintain railway traffic and pulled into their final position within short time. An intelligent control unit is responsible for the synchronization of the strand jacks. When displacing, upward as well as downward slopes can be overcome using automatically controlled brake cylinders.
The latest generation of Paul strand jacks is based on more than 20 years of experience with strand jacks and more than 60 years of experience in the field of multi-stressing of strand anchors on construction sites. This know-how was brought into the completely new development of the synchronized stroke control for controlled movement of heavy loads.
