Released in the the US market in 2011 the Liebherr 81k offers eleven variable hook heights. As well as the standard 26 m hook height, a range of configurations are possible without using the climbing facility to insert additional tower sections: four additional intermediate hook heights, a 30-degree steep angle jib position and a 45-degree angle to keep the jib clear of obstructions. If further tower sections are inserted with the climbing mechanism, six more hook heights up to more than 40 m are available with the jib horizontal.

While no longer in production, the Liebherr 81 K was part of the K series that offers exceptional flexibility for adapting to different construction site requirements. Variable hook heights and precise jib positioning enable optimal placement in even the tightest of spaces. So you can get your machine to where it’s needed, efficiently and with precision. Liebherr ensures that your crane and construction site are a perfect match. Since their market launch, Liebherr’s K cranes have established themselves as a versatile solution for the most diverse lifting tasks – from detached family houses to large-scale industrial projects. Equipped with modern drives and intelligent assistance systems, the cranes in the K series are based on a proven concept with quick assembly. Flexible adjustments to hook heights and jib lengths, along with optimised external dimensions, mean they can even be used where space is very limited.​​​​​​​
