The space is narrow between the machining centres in the production building for steel components at Liebherr-Hydraulikbagger GmbH in Kirchdorf, so it is the perfect location for the com-pact Liebherr LTC 1045-3.1 telescopic mobile crane. In fact, two 45-tonne models provided by Schmidbauer crane and heavy transport contractors were used to replace the crane track for a gantry crane.

Since excavator components are becoming larger and heavier, the capacity of the indoor crane also had to be increased. By replacing a total of eight girders for the gantry crane it was possible to double its lifting capacity from 20 t to 40 t. Two mobile cranes were used for this work to en-hance safety when hoisting and assembling the girders, each of which weighed in at 6 tonnes.

Since there was very little space between the girders and the existing installation system, the two LTC 1045-3.1 models were fitted with an assembly jib. In addition, it was not possible to use a hook block. Once again the concept of the compact Liebherr LTC 1045-3.1 proved to be ideal for use in constricted production buildings.

The LTC 1045-3-1
The LTC 1045-3.1 compact crane is a special crane for use in constricted areas and is particularly compact and manoeuvrable. It enables crane work to be carried out in extremely tight areas through which conventional all-terrain mobile cranes cannot pass or can only do so with severe restrictions. The LTC 1045-3.1 provides the outstanding handling features of classic all-terrain cranes whilst its compact design also makes an ideal hoisting unit for working in highly constricted places such as industrial buildings.
