Liebherr’s fast climber
Fast climbing 1000 EC B 125 undergoes extensive testing
The new Flat-Top crane managed to hoist loads of up to 158 tonnes.
Liebherr has carried out an intensive series of tests on its new 1000 EC B 125 Litronic Flat-Top crane, first unveiled last year at Munich.
The tower crane has been designed with new climbing equipment, developed to ensure particularly fast, safe and simple climbing. At around 45 minutes, each stage in the climbing process can be completed twice as fast as with conventional climbing equipment.
The tests, carried out at the test site of the tower crane unit Liebherr-Werk Biberach, measured the performance of the new climbing equipment but also includes dynamic and static overload tests.
A cable-based remote control for the hydraulic unit makes the job of climbing much easier, since 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 tonnes were supplemented with dynamic and static overload tests. The static overload tests were carried out using 125% of the maximum lifting capacity. The new Flat-Top crane managed to hoist loads of up to 158 tonnes.
