Austrian crane rental company Prangl deployed a 700-ton mobile crane for the installation of a pedestrian bridge in Austria. The specialized operation demonstrates how crane rental companies are increasingly involved in complex infrastructure projects and what technical requirements arise in the process.
The bridge assembly required precise planning and highly specialized equipment. The deployed crane had to not only lift the bridge structure but also position it exactly – a challenging task given the total weight of 700 tons. In addition to pure load capacity, such operations require comprehensive static calculations, coordination with authorities, and an experienced assembly team.
Prangl is one of the leading crane rental companies in the German-speaking region and operates one of Europe's largest heavy-duty crane fleets. The company specializes in infrastructure projects such as bridge installations, wind turbine assembly, and industrial heavy-load transport. Demand for such services is increasing: across Europe, thousands of bridges need to be renovated or replaced in the coming years – a market that favors specialized crane rental companies with heavy-load capacity.
Technically, bridge assemblies place special demands on the crane boom, the support, and load distribution. In a 700-ton operation, the chassis of the crane must be dimensioned accordingly and the ground must be capable of bearing the load. Additional counterweights and special support systems are often used to ensure the required stability. Assembly often takes place during night shifts or low-traffic times to avoid disrupting traffic on surrounding roads.
This case also demonstrates the strategic importance of a broad-based crane fleet: infrastructure projects require not only large tonnage but also quick availability and flexibility in configuring booms and supports. Crane rental companies like Prangl therefore continuously invest in heavy-duty cranes and specialized equipment – a trend that can also be observed among other European rental companies. Current projects such as the Sieg railway bridge in Germany demonstrate the growing importance of this market segment.
For infrastructure operators and construction companies, this means better availability of heavy-load capacity, but also increasing competition among rental companies. In the future, digital planning tools and telematics systems are likely to play a greater role in planning operations more efficiently and optimizing the utilization of expensive heavy-duty cranes.
