The 53 K fast-erecting crane will be unveiled to the public for the first time at the Bern 2014 Construction Machinery Exhibition. The new design of the 50 mt class crane is based on the successful K series concept and closes the gap between the 42 K.1 and the 65 K. The new fast-erecting crane with a truss construction and improved erection kinematics delivers more power, variability and safety on site.
The 53 K achieves a maximum hook height of 31 m which is the top value in the 50 mt crane class. With the rapid climbing system, up to three complete tower sections can be inserted practically and safely. This means that the hook height can be adjusted to suit the site situation. With the 20° jib luffed position, the maximum hook height can also be increased to 43.1 m.
With a horizontal jib, the 53 K can be configured with seven different hook heights between 15.8 m and 31 m. This makes the new K crane ideal for use on multi-occupancy residential buildings with up to eight storeys.

Liebherr aumenta da 14 a 16 anni la durata complessiva delle proprie funi in fibra, mentre la durata di utilizzo, determinante ai fini dell’impiego, aumenta fino a 12 anni. Alla base di questa decisione vi sono prove di invecchiamento pluriennali condotte su banchi prova e analisi delle funi già in servizio. La nuova disposizione si applica automaticamente a tutte le funi, sia quelle nuove sia quelle già in servizio.

Five questions that show why planning a tower crane deployment is more complex than you might think
On spectacular construction sites, it's the structures that take the spotlight. But building bridges, tunnels or skyscrapers in the first place often demands equally extraordinary crane concepts. From the Sagrada Família in Barcelona to the Fehmarnbelt Tunnel in Denmark, Liebherr supports demanding tower crane deployments worldwide. Max Widder, Head of Project Planning at Tower Crane Solutions, gives insight into the challenges behind some of the most complex crane projects in the world.
