bauma '04.2019

Munich (Germany), 8 April 2019 – Liebherr has updated its existing four-axle crane and will present the new MK 88-4.1 at Bauma 2019. The additional number at the end of the product name reflects the 4 axles and that it is the first version of this crane type. Featuring proven MK technology, this mobile construction crane is even more powerful and flexible than its predecessor. This is especially evident in a luffed jib position.

New elements include, for example, its different axle load options, which make the crane significantly more economical. The construction machinery manufacturer has also taken the environment into account: The MK 88-4.1 can operate emission-free using even less power than its predecessor.

Both the 8,000-kilogramme maximum load capacity and the maximum radius of 45 metres remain the same. The maximum load capacity of 2,200 kilogrammes at the jib head also remains unchanged compared to the MK 88 Plus.

A new ballast concept makes different axle load options and, in turn, more areas of application possible. Therefore, the MK 88-4.1 has 3 different axle load variations. With additional ballast, the axle load amounts to less than 13 tonnes per axle. With only basic ballast, the Liebherr mobile construction crane has an axle load of under 12 tonnes. Without basic ballast, the axle load can be reduced to less than ten tonnes. This means that, for instance, the crane can even be driven on bridges and roads with axle load restrictions. By means of an adapted load curve, powerful operation is still possible with the ten-tonne version.

In addition, the MK 88-4.1, like the MK 140, can be used with half-sided support, so that possible road obstructions can be avoided. The standard support width is 7.0 m and can be reduced to 5.75 m if necessary.
