No reported injuries in East London South Africa as a jib of what, from the grainy picture, appears to be a Potain 178 (US designation) buckles in winds. The highest reported speed was 55 kph which is about 33 mph. the wind speeds up just 100 feet are often higher, but even a crane locked off and facing 50 mph winds shouldn't collapse without some sort of defect. I'll keep digging on this story and hopefully next week some rumors will escape to address why a modern jib would buckle from moderate minds. This jib is tall and narrow, but I suspect that there is more to story. By the way, don't side load a tower crane jib or it might look like this.
