Impressed by Marr’s track record in designing and delivering large-scale lifting solutions on similarly challenging projects in Australia and around the world, DLSY (Daelim – Limak – SK E&C – Yapi Merkezi) Joint Venture challenged Marr’s team to develop a solution that would decrease the project’s construction time and associated risk for the project. With a total bridge length of 4,608 metres, a central span of 2,023 metres and a total bridge tower height of 318 metres, the feats of engineering required to complete the world’s longest span suspension bridge are staggering. The world-first manoeuvre is the first of many engineering feats that Marr’s tower cranes will be involved in during construction of the bridge. The second crane was carried out onto the water on November 8, with both cranes now set up and ready to begin work on the 1915 Çanakkale Bridge. On November 3, the first M2480D was lifted and transported a kilometre to the middle of the Dardenelles (Çanakkale Strait) by a ‘Taklift 4’ floating heavy lift barge crane, which has a lift capacity of 2200 tonnes. The unprecedented lift has seen Marr’s M2480D Heavy Lift Luffer (HLL), which at 600 tonnes weighs more than an A380, lifted in one piece – the first time a crane of this size has been lifted fully-assembled.Īfter being shipped from Sydney in pieces to a dry dock at Gallipoli (Gelibolu), two of Marr’s 2480D cranes were assembled onshore on purpose-built foundations. Australian crane company Marr Contracting Pty Ltd (The Men From Marr’s) has completed a never-before-seen engineering feat with its 330t capacity tower crane lifted into location fully assembled to assist in the construction of the world’s longest span suspension bridge in Turkey.
