PRODUCT FOCUS Johnson Crane Hire's LG 1750 lattice boom mobile crane. CASE STUDY: BOOM IN WIND FARMS BRINGS IN LOCAL LIFT SPECIALIST By Tarren Bolton With 465 wind turbines to be constructed in South Africa over the next two years, specialist heavy lift unit Johnson Renew has put its weight behind the country’s renewable energy projects – literally. This specialist lifter has bolstered its fleet with two additional 750 Liebherr LG 1750 lattice boom mobile cranes with super lift configuration to meet the exacting demands of lifting work on new and existing wind farms. Cornelis Grotius, general manager of Johnson Renew, a division of market leader Johnson Crane Hire focused on the renewable energy sector, has confirmed it is bringing in two additional 750 Liebherr LG 1750 lattice boom mobile cranes with super lift configuration to bolster its fleet of fit- for-purpose mobile cranes to meet the exacting demands of lifting work on new and existing wind farms. “It is exciting to see these projects finally pushing ahead, following the sign- off by the Department of Energy and Eskom last year. While we are looking forward to working with a number of www.equipmentandhire.co.za the 12 projects most recently approved in Round four of the government’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP), we have already secured several contracts,” Grotius says. Johnson Renew has years of experience and successfully completed lifts for the construction of several wind turbines at various wind farms including West Coast 1, Chaba, Waainek, Tsitsikamma, Gibson Bay, De Aar 1 and De Aar 2. It has also supplied transport, cranes and installation services to the Ombepo wind farm – Namibia’s first wind farm – located near Luderitz. Grotius confirms that Johnson Renew has secured the crane services contracts for the 120MW Golden Valley Wind Farm near the town of Bedford in the Eastern Cape, the 32MW Excelsior Wind Farm near Swellendam in the Western Cape, the 140MW capacity Kangnas Wind Farm located near Springbok in the Northern Cape and the 120MW Perdekraal East Wind Farm north east of Ceres in the Western Cape. The first of these lifting contracts, at Excelsior Wind Farm, started in June 2019 where 13 turbines would be installed. This will be followed by the Kangnas and Perdekraal contracts which will see 61 turbines and 48 turbines installed respectively. Installation of the turbines at Golden Valley is scheduled to begin in September 2019. This, Grotius says, is where Johnson Renew’s technical expertise including the provision of abnormal load transport, cranes and installation services will come to the fore. “Wind generator turbine (WGT) components are imported from overseas, while tower sections – in steel or concrete – are typically manufactured AUGUST 2019 19
