Twelve of the RTGs have eight tires that can rotate 90 degrees and the remaining 24 RTGs have 16 tires that can simultaneously rotate 360 degrees. Each of the cranes weighs about 145 tonsne, and are 27 m high, 25 m long and 11 m wide. The RTGs have a lift capacity of 40 tonnes

The Port of Singapore is one of the world's busiest. Operated by PSA, the port handled 29.37 million TEUs of containers in 2011.
