In combination with our strand jack and skidding systems, special steel constructions make it possible to lift loads to planned heights without a steel structure being on-site. The special steel construction takes on a bridging function here. In a modular system, the individual columns and steel beams can be combined with each other in various ways. In this way we ensure that loads can be moved precisely to any height. Preassembly before deployment increases flexibility and enables these structures to be used within a very short period of time.
