Liebherr has unveiled major advancements to its K series of fast-erecting cranes, integrating cutting-edge technologies aimed at boosting safety and operational efficiency. The latest models in the series—43 K, 61 K, 91 K, and the updated 125 K—now feature five intelligent assistance systems. These include sway-free load lifting without diagonal pull, enhancing safety for both personnel and crane components, alongside semi-automated lift functions designed for ease of use.
In addition, the cranes are equipped with the new Liebherr Control 5 system and the Tower Crane Operating System 2 (TC OS 2). These systems offer intuitive navigation with user-friendly symbols and icons, while a standardized radio control is now available across all cranes in the current K and L series, simplifying operations further.
