Video: Giant cranes arrive at new London Gateway port Three new giant cranes have been delivered to new deep-sea port in the Thames Estuary, at a site near Stanford le-Hope in Essex. The quay cranes, which are taller than the London Eye and weigh 1,848 tonnes each, measure 138 metres in height - two and a half times the height of Nelson's column in Trafalgar Square. "The size of the cranes future-proofs the port, allowing London Gateway to handle the next generation of ultra large container ships," said London Gateway operations director Tim Halhead. The cranes will be used to lift containers from some of the world's largest cargo ships onto the shore at the new London Gateway port, which is due to open at the end of 2013. When complete, its owners, Dubai-based DP World, say it could bring 36,000 jobs to the economy.
