Jærbetong AS Nærbø is one of the customers. They had major challenges with time consuming loading of Platen-deck and Bubble-deck elements. Loading of a truck could take up to an hour.
Nordic Crane took on the challenge of developing specially designed lifting gear that should be able to load one truck in a single operation . The concrete elements consist of only a thin layer of concrete and are very fragile. The items must be handled carefully to avoid the cracking during load handling. Ove Scheie at Jærbetong had studied loading operations at competitors and we had constructive dialogue . The final solution was adapted to the customer’s own overhead crane with two synchronized trolleys.
The system consists of two hinged spreader beams which are handled by each of the two synchronized trolleys. The spreader beams can be connected to two, three or four lifting beams under each stack. The construction with hinged spreader beams ensures even distribution of load between the beams and minimal stress on the elements.
Ove Scheie at Jærbetong AS is pleased with his new lifting gear. The loading that previously took up to an hour, is now done in 10-15 minutes.
