Kran-Maier GmbH & Co. KG from Landshut has modernised its crane fleet with a Liebherr LTM 1070-4.2 mobile crane. The Bavarian crane rental company is replacing an older 60-tonne telescopic crane with the new 70-tonner. State-of-the-art technology was an important criterion in the decision.

Managing Director Susanne Maier explains the decision in favour of the Liebherr LTM 1070-4.2 mobile crane:

The LTM 1070-4.2 is not only a crane that has proven itself over many years, but is also at the cutting edge of crane technology. For example, it already complies with the new Stage V exhaust emissions directive and the currently attached counterweight is automatically detected. We also ordered the VarioBase variable outrigger base and the radio remote control. It was also important for us that the delivery time of the crane was acceptable.

State-of-the-art crane technology

Liebherr initially launched the 70-tonner with 50-metre telescopic boom on the market with the type designation LTM 1070-4.1. Technical innovations such as speed-dependent rear-axle steering, disc brakes and the new LICCON2 control system were integrated in 2008 and the type designation was changed to LTM 1070-4.2. Liebherr has continued to keep this model at the cutting edge of mobile crane technology ever since. Technical innovations such as VarioBase, ECOmode, a new crane cab, new one-piece steel rims and the latest generation of disc brakes have always been incorporated. Liebherr has now delivered more than 2,000 cranes of this type worldwide.

First use: erecting high-voltage pylons

Since November last year, Deutsche Bahn has been having pylons on the high-voltage line between Buch and Eching replaced. The reason for this is the age of the pylons, which were built as early as 1926. This is a traction current line for supplying electrified railways. The new pylons will be placed on the existing foundation and brought up to the current state of the art.

Kran-Maier sent its new LTM 1070-4.2 to support this project immediately after delivery. It took over the erection of some masts between Eching and Viecht. Crane operator Bennet Kühl is full of praise for his new work equipment:

“The crane runs very smoothly and the control is precise. The remote control is great.”

The assembly of precast concrete parts, lighter garages and steel construction are other fields of application that Kran-Maier is planning for the new 70-tonner.

Susanne Maier, together with brother Florian and father Erich, is now the third generation to run the family business. The largest of the ten mobile cranes is a Liebherr LTM 1250-5.1. She says:

We are attached to our cranes and keep the equipment a little longer. Customer service and the supply of spare parts are very important to us. Liebherr is exemplary here.
