A number of giant cranes are due to arrive at a new deep-sea container port in Essex. It is the second delivery of cranes to the London Gateway in Thurrock. The first cranes arrived earlier this year and were transported upright on a ship.
They are the biggest ever cranes to be delivered to the UK. They weigh 2,000 tonnes and stand at 138 metres tall - that is two and a half times the height of Nelson's column. In fact, they are so tall it would be possible to roll the London Eye under the lifting arm.
Once the port is fully operational, London Gateway will have 24 cranes on the quayside.

Essex County Council has today pledged its support to the Thurrock Council taskforce being set up following the announcement of the possible closure of the Coryton Oil Refinery.
The site’s administrators Price Waterhouse Coopers announced yesterday that they had been unable to find a buyer for the refinery and were seeking to start negotiations with unions and employers over its closure.
This would mean the loss of up to 500 jobs at the refinery and impact on other companies providing services to the site.
