Road maintenance

The challenge

Roof construction

In order to provide more space for employees and devices, the Burgenland building department built a new road maintenance department location on the Stoob-Süd dual carriageway sliproad. Known for its reliability and innovativeness, Prangl was given the responsible task of using special equipment to support construction of the wooden roof beams.

Our solution

Lifting wooden elements

On a 25,440 m² plot, the new base with a management building, workshop, inspection body, central warehouse, covered parking spaces for the fleet, garages, fuel station, salt silos including a brine mixing system and washing boxes. Sustainability played an important role from the start of plans. The strategic specifications imposed regarding electric mobility, photovoltaics, using sustainable materials were met completely. Due to the high efficiency, the roof beams are made of a wooden structure and comprise a total of 11,000 m².

PMBRK 240

The key player is a new mobile construction crane with a maximum load of 18 tonnes, a lifting height of 56 metres and a maximum radius of 42 metres. The PMBKR 240 is therefore particularly practical, as it has a crawler chassis. This enables the crane to be moved quickly. This mobile construction crane was perfectly suited to the combination of load situation and radius required on site. The basic crane unit was delivered overnight due to roadworks on the Burgenland dual carriageway.

High weights, wide radius

The crane was first used to move glulam beams, ceiling beams and the ceiling of a production hall. Parts each weighing 3.6 tonnes and with a height of around 12 metres were lifted at a radius of up to 42 metres. The supports had a length of 25 metres. The radius was sometimes very wide due to the local conditions on the building site. The parking space for HGVs with deliveries took up a large amount of space and so the crane had to work from a great distance. In addition, a scissor lift with a working height of 15.0 metres and two telescopic boom lifts with a working height of 15.6 metres were also used.

Seamless process

The required coordination with external companies worked seamlessly thanks to the Prangl team’s experience. Moving the individual wood components also did not pose any challenges for people or machines, and the building progress conformed to the customer’s concept. The new road maintenance department will have space for 110 employees to work and is planned to start operating in June 2024. All Prangl devices will remain on site until February 2024 in order to complete the lifting work for the remainder of the building.
