The MK 120-5.1 is the latest addition to Liebherr’s mobile construction crane range. The five-axle machine bridges the gap between the MK 88-4.1 and the MK 140-5.1. Alongside reliable lifting power, it features a new display and an optional smaller load hook for working in confined spaces.
With a jib measuring 52 m and a maximum lifting capacity of 2,100 kg at its jib head, the new MK 120-5.1 delivers performance on the jobsite. Its small turning circle facilitates site access via narrow streets and intersections.
The new crane is based on the MK 140-5.1. Crane operators who know how to operate this model can work with the new one with minimal training.
New Display
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 flexible customization by the crane operator. Its 12‑in. touch display can be used in split and full screen mode. This means that diverse information can be displayed across different screen areas. The display is set to replace the existing version in all mobile construction cranes by the end of 2025.

Smaller Load Hook for Load Positioning
The MK 120-5.1 can be ordered with an optional smaller load hook. This version is applicable to 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 onsite. The smaller load hook can handle the same lifting capacity as its large counterpart and will be available for all Liebherr mobile construction cranes in the future.
“The MK 120-5.1 is exactly the right crane for our fleet. Its jib length and lifting capacity make it ideal for our customers’ construction sites,” said Stephan Zaugg, managing director at Zaugg AG Rohrbach (Switzerland). “We are excited to be the first ever customer to acquire the new MK. Reliability, customer service and the great reputation of Liebherr’s mobile construction cranes were deciding factors for our purchase."
