A brand new 1,250 tonne Kobelco 16000 J-H crawler crane collapsed while undergoing final tests on July 26th at Kobleco’s plant in Takasago, Hyogo Prefecture, Japan.

The boom, jib and derrick mast collapsed sideways striking a number of buildings and vehicles in the vicinity. A man working in the immediate area, Tadashi Yamaguchi, 56, was declared dead at the scene, while Shihei Nishida, 23, secumbed to his injuries and died later in hospital. A third man aged 59, remains seriously injured. Others working in the area or the buildings affected received minor injuries.

From the photos and many videos posted locally, it looks like the derrick mast was ripped off its pivot pins, while the boom failed at the connection with the butt section.
