Liebherr to introduce four mobile cranes at bauma

Liebherr will unveil four new products from its mobile cranes product division at bauma in Munich, Germany in April.

The mobile cranes division will unveil the new 8-axle mobile crane, designed for maximum performance and a 5-axle crane, which was designed for economical and flexible crane jobs.

As well, two of the new cranes headed to bauma were presented at Liebherr’s 2018 customer days at its manufacturing plant in Ehingen — the 5-axle 230 tonne LTM 1230-5.1 mobile crane and the LR 1800-1.0 crawler crane with a maximum lifting capacity of 800 tonnes.

The new LTM 1230-5.1 features a 75 metre telescopic boom. Its predecessor, the LTM 1200-5.1, also had one of the longest telescopic booms in this crane class at 72 metres. The new 230-tonne crane not only delivers an extra 3 metres in length, but also an average of 20 per cent greater lifting capacity. In addition to a multi-functional folding jib, a 43 metre fixed jib is also available.

The engineers at Liebherr-Werk Ehingen GmbH placed the multi-award-winning VarioBase support technology at the focus of the structural steel construction when creating the concept for the new crane. This means the new LTM crane is the first to have an asymmetrical support base — with a width of 7.4 metres at the front and 8.1 metres at the rear.

VarioBase means it is now possible to generate particularly high lifting capacities, particularly at the rear working area over the 8.1 metre wide supports – calculated in real-time by the LICCON controller.

The new “VarioBase Plus” digitalization ability has a major influence on the structural steel technology and enhances lifting capacity.

Outstanding lifting capacities and low cost transport are the main features of Liebherr’s new 800 tonne crawler crane.

The LR 1800-1.0 has been designed as a powerful industrial crane for jobs with a luffing jib and derrick system.

For the first time, the boom system features lattice sections with three system dimensions, which can be telescoped into each other for transport.

The new LR 1800-1.0 is currently the most powerful crawler crane on the market, even though the basic machine is just 3 metres wide.

It is particularly rigid as a result of its increased design height. A quick connection to raise the superstructure for transport is standard.

The new LR 1800-1.0 also features a derrick ballast with VarioTray – after raising the lattice boom with the large derrick ballast, part of the ballast can be unbolted quickly and easily.

Only a small proportion of the ballast is generally required for hoisting work with the boom fully or almost fully raised. This avoids the tiresome stacking and unstacking of ballast slabs.

A new type of ballasting system is used for the suspended ballast – a hydraulically adjustable folding frame allows the ballast radius to be adjusted to up to 23 metres. This means a fixed guiding frame system is no longer required for large radii.
