After being founded in 1924 as a building construction business, the company invested in its 100-tonne machine 100 years after the date of its inception to help expand the company’s taxi-crane capabilities, with Wilhelm Bruns, the third-generation Managing Director of the family business labelling the time of the delivery as “perfect”.
“The LTM 1100-5.3 offers us exactly what we need: maximum mobility thanks to its low axle loads and width of just 2.55m, which is ideal in a big city like Hamburg,” he said.
“At our subsidiary Alex Grund GmbH in Hamburg, the new LTM 1100-5.3 has replaced an LTM 1095-5.1, which has provided us with reliable service for 12 years.”

The 100-tonne crane, according to the manufacturer, sets “new standards” for flexible axle loads. With 0.8 tonnes of ballast, it reaches a total weight of 44 tonnes with axle loads of 9 tonnes. With 4.4 tonnes of ballast, it can travel with 10 tonnes of axle load and a total weight of 48 tonnes. With an axle load of 12 tonnes, the 100-tonne machine can carry up to 16.9 tonnes of counterweight, which equates to 75 per cent of the maximum ballast of 22.5 tonnes. This allows the new LTM 1100-5.3 to perform the majority of its jobs as a taxi crane without additional ballast transport. Another highlight of the LTM 1100-5.3 is the new LICCON3 crane control in conjunction with the new Liebherr cab design.
The LTM 1100-5.3 represents a continued relationship between Bruns Kranvermietung and Liebherr that began three years ago with the Lüneburg company’s LTM 1070-4.2 – a crane that the director labelled as mobile, flexible, and innovative.
“Since then, we have ordered all our cranes from Liebherr,” said Bruns. “Liebherr has the right products for our fleet and has shaped developments in the mobile crane market.”
