Enerpac has completed a factory acceptance test (FAT) of a JS-250 jack-up system fitted with a bracing kit for Germany’s LASTRO Heavylift, lifting a 660-tonne load at a height of 15 m.
The Enerpac JS-250 system, comprising four towers, can lift loads up to 1,400 tonnes to 5 m and 1,000 tonnes to 10 m. The bracing kit includes four specially designed mid barrels, four adjustable braces and eight diagonal tension bars. The mid barrels are added to the tower and the braces and tensions bars fitted at ground level. The jack-up bracing arrangement is then raised synchronously as more barrels are added to the tower.
According to Enerpac, the bracing system is especially useful when side loads are expected, for example, when deploying the JS-250 jack-up system SPMTs during bridge construction.
In addition to the JS-250 jack-up, LASTRO has invested in the enlargement and modernisation of its equipment fleet with 200-tonne and 70-tonne Enerpac strand jacks, as well as an Enerpac SCJ-Series 100 cube system.
“With larger and heavier loads in often space restricted areas, the compactness of the Enerpac systems will allow us to offer an effective lifting solution that is quick to implement,” said Katja Marmann, ceo of LASTRO Heavylift. “The jack-up and cube jack systems are highly capable lifting systems for many projects where it’s not possible to use traditional cranes, especially inside factory and production buildings.”
