RT overturns on highway

WRITTEN BY

A Rough Terrain crane working on Interstate highway I17 near Bumble Bee, to the north of Phoenix, Arizona, overturned yesterday.

The cause of the overturn was due to the operator retracting the outriggers on one side of the crane, while the crane’s boom was retracted but fully elevated and over the side, making the machine back heavy.

No one was hurt in the incident although the road was closed for a short spell while two truck cranes came to the rescue of the stricken RT.
