Specialist contractor Uchimiya Corporation in Japan overcame high winds and confined space on a recent installation project. It used a pair of crawler cranes to install bridge sections on a site where the cranes had minimal space for tail swing when slewing.

Uchimiya is one of the largest contractors in Japan and used its Kobelco lattice boom crawler models 7800 and SL13000, of 750 and 800 tonnes maximum capacity, respectively.

Overnight from the 20th to the 21st of January the bridge beams were installed on the new Wangan Line expressway in Tokyo. Block A was a 39 m long, 253.6 tonne section. Block B was 17.3 m long and weighed 82.2 tonnes.
