High tech cost-effective
alternative to cranes

More than 30 years ago, VSL came up with the visionary idea to use a combination of proven components from its strand post-tensioning system along with hydraulic jacks and pumps for lifting heavy loads.

As an initial application in Sardinia, three 490-ton concrete dome shells for a series of circular aluminum silos were lifted a height of 28 m and then fixed into their final position. Lifting and stressing of the steel cable net system for the acrylic tent-shaped roofs at Munich's Olympic Stadium in 1971 served as another milestone in the implementation of this new erection technique.

Strong growth in the market for alternative heavy lifting (lifting by means other than cranes) reveals that the strand-lifting technique has more than ever become state-of-the-art and that VSL continues to be a major player in this market.

Both the equipment and its controls have been improved and new fields of application opened up for this technique. VSL's Heavy Lifting system has contributed to enhancing quality, compressing construction schedules and saving costs. VSL continues to stand for innovative engineering, high safety standards and reliable performance.
