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 plenty of lifting power, it features a new display and an optional smaller load hook for working in confined spaces.
Biberach (Riß) (Germany), 18 September 2024 – With a jib measuring in at 52 metres and a maximum lifting capacity of 2,100 kilograms at its jib head, the new MK 120-5.1 delivers impressive performance. The crane marks an expansion of Liebherr’s existing MK portfolio and bridges the gap between the MK 88-4.1 and the MK 140-5.1. One of the mobile construction crane’s key advantages is its agility; its small turning circle facilitates site access via narrow streets and intersections.
The new crane is based on the established MK 140-5.1. Crane operators who know how to operate this model can work with the new one without extensive additional training.
New crane, 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 ease of use and flexible customisation by the crane operator. Its 12‑inch 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 optimal load positioning
The MK 120-5.1 can be ordered with an optional smaller load hook. This version really comes into its own 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.
“Exactly the right crane for our fleet”
The first customers are already full of praise for the latest addition to Liebherr’s mobile construction crane range. “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,” says 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.” A company from Belgium has also already put in an order for the MK 120-5.1. Deliveries will start in summer 2025.
