Press releases | 01/28/2019 Liebherr 125 K: the largest fast-erecting crane in its class

  • Available from March 2019
  • Available worldwide
  • Radius of up to 55 metres with a slewing radius of 3.2 metres

Liebherr will present a new fast-erecting crane at Bauma 2019: the 125 K. With a radius of 55 metres and a maximum hook height of 65.5 metres, it is currently the largest fast-erecting crane on the market.

New: the Liebherr fast-erecting crane 125 K – currently the largest in its class on the market.

The new 125 K has been specially developed for civil engineering requirements such as road traffic bridges and commercial as well as industrial building construction. In this field, high load capacities and large radii are required for projects with limited lead times.

A hook height of up to 65.6 metres

The 125 K has a considerable initial hook height of 29.5 metres as standard. Five tower sections can be additionally inserted to reach a total hook height of 41.5 metres. This means that even major construction projects can be mastered. If the hook height still isn’t sufficient, the 30° luffed jib position enables an impressive 65.5 metre hook height. The Liebherr crane has an 8,000 kg maximum load capacity and with a 55-metre radius at the jib head, it is able to lift 1,300 kg thanks to its Load-Plus function. Its immense flexibility is also demonstrated by its five radius options, ranging from 35 to 55 metres.

Flexible deployment even in tight spaces

Construction site conditions are becoming increasingly tight and therefore require construction cranes to have compact dimensions to match. With its 3.2 metre slewing radius, the Liebherr 125 K fast-erecting crane is consequently able to fit into very small spaces. Thanks to its variable slewing radius, which can be extended to 4.0 metres, the amount of transportable ballast can be reduced – which in turn reduces costs.

Everything always in view

In addition to familiar features such as the Micromove fine positioning mode and Liebherr’s two-line operation Speed2Lift, further improvements have also been thought out in detail: For example, site lighting is now available with LED floodlights to ensure even better site illumination.

Of course, the external K-crane cabin is also available for the 125 K – especially an advantage for larger sites where 125 Ks are typically in action. This way, the crane driver always has the entire construction site in view.

Simplified transport and electronic stability control

Until now, large fast-erecting cranes could only be transported via semi-trailer. As not every customer has access to a suitable tractor vehicle, Liebherr has now expanded the transport options: The 125 K can also be towed as a trailer by a conventional truck. For this, Liebherr Tower Cranes now offers a new solution: the axle system LiTRAX.

Liebherr has developed a new 80 km/h high-speed axle that is suitable for the current fast-erecting crane range. It can be used in a modular manner and consists of three units: a front axle as well as one rigid and one steerable rear axle. As a result, a 53 K or a 65 K.1 can be transported using the front axle and only part of the rear axle. For an 81 k.1, a tandem axle can be assembled using two individual rear axle modules. Therefore, with these three units, it is possible to select the optimum combination for all Liebherr fast-erecting cranes, enabling them to be compact and flexible on site.

The axle system is equipped with state-of-the-art operation safety technology such as an electronic braking system that ensures fast response when braking. The highlight, however, is the electronic stability control system. Sensors measure the lateral acceleration and detect tilting tendencies early on. Breaking intervention is specifically applied to individual tires and the axle is stabilised. This prevents loss of control, especially in the case of unexpected braking manoeuvres or difficult weather conditions, and therefore ensures a significant increase in crane transport safety.

The front axle has a steering angle of 180 °, that of the steered rear axle being 27.5° in both directions. This makes tight manoeuvres with a small radius possible and also means that the cranes can be positioned in tight spaces.
