Tadano GT550E

In the previous model of Tadano’s truck crane, the carriers have been built by commercial vehicle manufacturers such as Nissan, but things took a turn when Yusoki Kogyo, the subcontractor of Tadano’s supplier Nissan, was taken over in 2004 by Fuji Heavy Industries and stopped producing crane carriers.

Hence, Tadano decided to produce their own carriers (TC-4255) for the truck cranes. The productions of the new carriers took place at their factory in Shido, Japan in January 2006 for the GT550E domestically and overseas.
