4,500t crawler from Sany

Chinese crane manufacturer Sany claims to have unveiled the largest crawler crane in the world with its 4,500 tonne SCC45000A.

We have not received the full specification yet, but in its twin boom configuration the crane has a maximum load moment of 98,000 tonne/metres. It features a 126.5 metre main boom plus a 15.5 to 48.5 metre fixed jib, while a 30.5 to 108.5 luffing jib can be added for a maximum system length of 216.5 metres, while its 62 metre twin Superlift back mast/derrick boom provides a ballast radius of 28 to 37 metres for its tracked counterweight system.
