Investigators are looking into whether wind was a cause of an accident involving a crane at the Port of Milwaukee.
One worker, who is 45, suffered an injured shoulder and elbow.
Milwaukee Deputy Fire Chief Randall Zingler said they received a call about the injured worker at about 8:55 a.m. Tuesday morning.
The Heavy Urban Rescue Team was dispatched to the Port of Milwaukee Cargo Terminal 2, at 1200 South Lincoln Memorial Drive, south of the Hoan Bridge.
The worker fell about eight feet from one platform on the crane to another part on the crane's bottom part.
A Port of Milwaukee spokesperson said the worker was lowering a boom on one of the cranes, trying move it from the second to the third terminal.
While he was moving the crane, a piece of equipment moved and knocked him off the platform.
Rescue crews extended a ladder, put the worker on a stretcher, slid the worker down the ladder, and put the worker in an ambulance.
Another supervising worker on scene was not hurt.
Milwaukee Police were also on scene during the rescue.
