The new Greiner HKT-500 (Hydraulic Climbing Tower), which RIGA-MAINZ renamed as Power-Lift-Tower, expands Greiner’s product portfolio again.

After a challenging development and construction phase, the system was put through its paces in Ehingen at the beginning of May 2021 with the kind support of Liebherr and subjected to a load test using the impressive LR13000.

As an expansion option, the lifting towers can be equipped with a chassis including a drive unit in the future.

Successful applications have meanwhile taken place in Kornwestheim, Trier and Italy, where bridge structures weighing up to approx. 2,000 tons have been positioned in combination with self-propelled axle lines. RIGA-MAINZ ordered another set of the 1,000 to. Lifting System GHS-3 540/1000. At Greiner, this order was used as an opportunity to completely overhaul the tried-and-tested system from a technical point of view and also to subject it to a facelift. The new lifting system generation from Greiner now has a significantly more compact design with an overall height of only approx. 2,500 mm. The latest monitoring and safety technology is used and all wheels are now driven. A linear synchronization control for larger wheel diameters makes the application even easier. Numerous features can be added to the modular system at any time. The lifting system has also impressively demonstrated its performance in initial use.
