Liebherr upgrades K series of cranes
Liebherr has upgraded its established K series of fast-erecting cranes, making the machines future-ready. Intelligent assistance systems for bottom-slewing cranes are no longer a distant promise; they are now available for all current K series cranes. K series cranes have been in action on construction sites around the world for years. They are continually improved further and adapted to the changing requirements of construction sites. The latest cranes in the series, the 43 K, 61 K and 91 K, are available now as well as the new version of the 125 K.

As part of the facelift given to the successful K cranes, the machines can now be ordered with Liebherr’s five intelligent assistance systems. Smart functions such as sway-free load lifting without diagonal pull increase safety for people and sensitive components, while semi-automated lifts maximise ease of use. Already established features, such as variable hook heights and manoeuvrability in tight spaces, continue to be part of the new series along with the familiar functions Speed2Lift, Load-Plus and Micromove for maximum lifting speeds, increased jib head lifting capacity and precise positioning of loads. The crane names now reflect the lifting capacities according to Load-Plus.

All new K cranes are equipped with the new Liebherr Control 5 crane control system. This consists of the control system, the Liebherr Display 5 and I/O modules. The robust and durable control system is already installed in the current L series of fast-erecting cranes and is used in a variety of construction machines within the Liebherr Group. The facelift also sees the K cranes equipped with the new Tower Crane Operating System 2 (TC OS 2). It features standardised and intuitive menu navigation, with self-explanatory symbols and icons. A standardised radio control for all cranes in the current K and L series is another new addition.
