The MK 120-5.1 is the latest addition to Liebherr’s mobile construction crane range, which features a 52-m jib and a maximum lifting capacity of 2,100 kg at its jib head. This five-axle model bridges the gap between the MK 88-4.1 and MK 140-5.1.

One of the MK 120-5.1’s key advantages is its agility; its small turning circle facilitates site access via narrow streets and intersections. Liebherr said the new crane is based on the MK 140-5.1, so crane operators who know how to operate this existing model can work with the new one without extensive additional training.

The MK 120-5.1 is equipped with the new Liebherr TC-OS display. The TC-OS (tower crane operating system) user interface focuses on ease of use and flexible customisation by the crane operator. Its 12-in touch display can be used in split and full screen mode – meaning that diverse information can be viewed across different screen areas. This display is set to replace the existing version in all Liebherr mobile construction cranes by the end of 2025.

In addition, the MK 120-5.1 can be ordered with an optional smaller load hook. This version is particularly useful on sites with existing buildings where scaffolding is in place and the load has to be moved between the building and the scaffolding. It only takes a few minutes to change the load hook on site. The smaller load hook can handle the same lifting capacity as its large counterpart and will soon be available for all Liebherr mobile construction cranes.
