The challenge

Efficient processes

Prangl was commissioned for an interesting building project in the north of Vienna: A new 14 metre high multi-storey car park was added to the Amazon logistics centre in Großebersdorf. The crane work had to be performed as efficiently and quickly as possible. Planning the processes was the greatest challenge.

Our solution

Crawler crane

The size and flexibility of the equipment to be used was the decisive factor. The key player in this large project was therefore a lattice boom crane with and off-road caterpillar track system and a maximum load of 280 tonnes, a main boom with a maximum of 119.1 metres and a maximum system length of 150.1 metres. Even the heaviest loads were able to be lifted without problems using these giants. The fact that this crawler crane can also be moved when loaded makes it the best piece of equipment for this type of job, as this makes positioning the items being lifted significantly easier.

Large crane in the centre

The lifting concept that was drawn up stipulated that the crawler crane should only be moved in the centre of the building to be built. Therefore, after setting it up and aligning it (main boom length of 34 metres and an adjustable fly boom length of 38 metres), it was moved around 100 metres into the centre of the multi-storey car park that was to be erected in order to start its work there. The first construction phase involved unloading the pillars that each weigh 12 tonnes, are 11 metres long and have a diameter of 0.6 metres, setting them upright and installing them. This phase covered 4 axles with 6 pillars each.

Repeating the work steps

The next step was to install the ice walls and to concrete them in using a crane and a concrete bucket. The beams that weighed 11.9 tonnes (each with a length of 7.6 metres, a width of 1.9 metres and a height of 0.5 metres) and had to be installed between the pillars were up next. The hollow floors (each with a weight of 12.4 tonnes, a length of 18.50 metres, a width of 1.2 metres and a height of 0.45 metres) for the first floor were then laid and the connection joints concreted using a concrete bucket again. The steps starting from the beams were repeated one by one for the next 3 floors.

Four construction phases

After this construction phase was complete, we moved on to the next one where the same work was performed. There were a total of four construction phases that reached a height of 14 metres at the end. Setting the corner pillars that weighed 12 tonnes upright took the crawler crane almost to the limit of its capacity due to the projection of up to 44 metres. The Prangl team's meticulous planning paid off and the crane work was completed on time and to the customer’s complete satisfaction.
