Big viaduct lifted by bigger crawler

14 January 2008


Japan crane rental company Uchimiya used a Kobelco 7800 SHL to set a viaduct girder weighing more than 240t.

The lift took place at night in the waterfront area of Ariake, in Koutou ward, Tokyo.

Uchimiya set up the Kobelco in super heavy lift configuration with 60m boom, 42m mast, with 240t of counterweight on the trolley at a distance of 16m. In this configuration, the crane could lift a maximum of 257.5t at 28m radius.

But the crane had no problem lifting the steel girder section, which weighed 243.6t, including lifting attachments.
