The challenge

Professional planning, perfect equipment

The positioning of two dryers, weighing in at 117 tonnes and 15 metres in length, demands several of Prangl’s disciplines. Thanks to professional engineering, the right – and probably also the only possible – procedure was quickly devised. The correct combination of chosen equipment was decisive for the success of this project.

Our solution

Two heavy duty transporters, each 39 metres long

The two sewage sludge dryers were transported on two separate days from Upper Austria to Vienna on a total of 18 axles. Their night-time transportation through Vienna was particularly spectacular. The trained Prangl drivers skilfully manoeuvred the 39-metre long heavy transport units through all of the tight spots in the federal capital. A 100 metric ton loader crane supported the transport with numerous traffic control measures, such as the temporary clearance of concrete safety barriers.

A job for the 500-tonne telescopic crane

Due to the limited space available on site, it was necessary to unload the extra-long containers with a 500-tonne telescopic crane. After brief interim storage, the yellow giant raised each respective dryer onto the PVSL 75 re-railing system. Only with this special rail system was it possible to move the objects into the destination building. The limited access height posed no problem either, thanks to the extremely compact design.

Great dedication from the Prangl team

The dryers were then finally pushed into their end position and correctly connected. The two new sewage sludge dryers have already begun drying dewatered sludge, which is subsequently blended with used oil and heating oil in a mixer. The combustion that follows this process generates electricity and district heating for the city of Vienna. Thanks to the dedication of the entire Prangl team, it was possible to complete the works ahead of schedule.

All departments at Prangl worked together to achieve the desired success.
