The Enerpac JS-250 jack-up system is a 1000t capacity multi-point, synchronous lifting system with self-contained hydraulics in each unit for uncluttered work areas. Loads are lifted in increments as steel barrels are stacked together to form lifting towers.
Working within tight space restrictions, the four tower jack-up system lifted the power generation plant equipment to a height of 4.5m. Using Collett’s SPMT capabilities, the 100t Siemens steam turbine and the 60t generator were manoeuvred on site within the plant and positioned above the jack-up units at each corner of the load. Following the 4.5m lift, Collett’s skidding systems allowed for both the generator and the steam turbine to be skidded for 14m into final position.
“The Enerpac jack-up system is perfect for this kind of job,” said Lincoln Collett, technical director. “We considered a gantry, but there was no space to move the gantry forward to position the turbine and generator. The combination of the jack-up’s synchronised lift and skidding worked very well.”
The Enerpac Jack-Up system is manufactured at Enerpac Heavy Lifting Technology in Hengelo, The Netherlands and compliments Collett’s heavy lift offering. Collett & Sons hydraulic jacking and skidding services facilitate the manoeuvring, positioning, extraction and relocation of cargoes in confined spaces, and by employing the JS-250 new jack-up system allows them to offer an innovative solution for undertaking these movements at height.
