An intensive series of tests is being carried out at the Liebherr-Werk Biberach GmbH test site with the new 1000 EC-B 125 Litronic flat-top crane which was unveiled at the Bauma 2013. This programme is designed not only to test the completely new climbing equipment but also includes dynamic and static overload tests.

The new climbing equipment was developed to ensure particularly fast, safe and simple climbing. At around 45 min, each stage in the climbing process can be completed twice as fast as with conventional climbing equipment. The cable-based remote control for the hydraulic unit makes the job much easier. The fitter is always at eye level with what is happening. The climbing process meets the high safety standard of the EN standard 14439. During the assembly of the prototype, the optimal erection procedures for climbing as well as jib assembly were further improved.

The test hoists with the maximum lifting capacity of 125 tonne were supplemented with dynamic and static overload tests. The static overload tests were carried out using 125 per cent of the maximum lifting capacity. The new flat-top crane managed to hoist loads of up to 158 tonne.
