Crane overturn in Austin

A man was injured when a lattice truck crane overturned in Austin, Texas yesterday. The operator was initial trapped in the cab, but managed to extract himself, he was not seriously injured.

The crane, owned and operated by Sun Crane, was lifting a concrete wall panel in a tilt up process, when it one of chains or brackets broke, allowing the load to drop, causing it to swing out of radius at the same time as a dynamic loading was applied as the other chains caught the load. As a result the crane lost stability.
