ABSTRACT:
The invention concerns a wind safety device for at least two outdoor cranes (2a,2b), able to move by traveling gears (6) on a jointly shared crane track (1), especially track-mounted full gantry cranes, with holding devices engaging at or in the region of the crane track (1) to prevent the cranes (2a,2b) from lifting up and being pulled away when certain wind speeds are exceeded, and it being possible to join together at least two neighboring cranes (2a,2b) in the region of the traveling gears (6).In order to achieve greater safety against the lifting up and pulling away of cranes (2a,2b) taken out of operation due to high wind speeds prevailing, it is proposed that impact elements (10a,10b) be arranged above the coupling on the at least two neighboring cranes (2a,2b), lying against each other when the at least two neighboring cranes (2a,2b) are coupled together.
