The new LTM 1055-3.3 from Liebherr sets completely new standards in terms of mobility on public roads. With its low overall weight, the crane offers an optimum solution for regions and projects where road licences and restrictions play a role.

Thanks to its innovative design, the LTM 1055-3.3 is also much easier to use on roads and bridges with limited load-bearing capacities. The crane combines high performance with maximum flexibility, enabling efficient operation, especially in markets with strict regulations on vehicle weights and axle loads.

The lower axle loads ensure more flexibility and greater economy in daily use. This eliminates the need for costly authorisations, escort vehicles and restrictions on the permitted driving time in many markets.

While its predecessor (the LTM 1055-3.2) can carry up to 5.5 t of ballast with a 12-t axle load, the new LTM 1055-3.3 can carry up to 9 t. This is about 80% of the maximum ballast, meaning that most crane jobs can be performed without additional ballast transport.

By simply removing the counterweight – which the crane does itself – axle loads of below 9 t and a total weight of approximately 26 t can be achieved. The LTM 1055-3.3 also features the new Liccon3 control system and a significantly lighter construction with the same boom length.

The lightweight design of the LTM 1055-3.3 has the added advantage of high mobility and high lifting capacities, particularly for medium and large working radii: the low weight of the telescopic boom enables high loads to be lifted in the working area, where the tilting of the crane is the limiting factor.

In the ballast configuration for 12 t of axle load, the LTM 1055-3.3 outperforms other three-axle models from a radius of around 8 m. From a radius of 20 m, it is even on a par with four-axle mobile cranes.

The new LTM 1055-3.3 becomes even stronger with the standard variable support base VarioBase Plus, especially in the working areas above the rear outriggers. The support base is wider here than at the front, as the rear sliding beams have a two-stage design.

With its 40-m telescopic boom and 15-m double folding jib, this 55-t crane can reach lifting heights of up to 54 m and radii of up to 46 m. A 1.9-m assembly jib has been newly developed, which can be angled to 50°. It is ideal for assembly work in industrial halls where space is limited.

The LTM 1055-3-3 also has other technical features that increase efficiency, comfort and safety. Road safety benefits from new intelligent assistance systems: the Blind Spot Information System (BSIS) and the Moving Off Information System (MOIS) support the driver and increase protection for road users such as pedestrians and cyclists.

In addition, LTM 1055-3.3 will be prepared for the use of RemoteDrive as standard – a radio remote control with which the crane can be moved from the outside, making it suitable for confined jobsites. To improve comfort and reliability, there are new options that have already been tried and tested on other models. These comprise a central lubrication system for the chassis and a digital tyre pressure indicator, resulting in excellent maintenance and availability of the crane.
