Dublin Ireland lost the jib of a Wolffkran in a windstorm over night. No injuries were reported but a apartment had to be evacuated and a rail line halted. Early reports focused on weather vaning the crane.
When a tower crane is out of service the slewing (swing) brakes are opened so that the longer jib of the crane can point in the direction the wind is blowing and change directions with the wind. This keeps the crane profile as small as possible and since cranes are counterweighted then lean back, and weathervaning allows the crane to lean into the wind just like when we try to walk away from the wind.
One of the things we are doing these days is delivering some of the best forklift gear on the market. We are the North American Distributor for Eichinger out of Germany. We have several hundred attachments that we manufacture in a state of the art factory in Germany. seattletowercrane.com is the website
We have concrete buckets, conventional and laydown. Flying forks so you can safely lift pallets. But if you want to go further we have crane materials baskets for one or two pallets. Retains everything inside the cage. Some of the options we have aren't even new, they just never made it across the water. Bulk bins stack and are crane rated with a four point lift. From 0.6 yards to 5.3 yards in size. They can also dump out on the back lifting eyes, or you can access the materials while they are still stacked. Great for concrete construction. The line up is much deeper than this. It's the best gear on the planet.

weather had a significant factor with this incident but so too had some erection issues of the crane as a detailed report later found out.A jib pin had been inserted the wrong way i.e. upsidedown.together with the wind it worked its way out over time and hence the jib collapsed.The report also found that the operator had engauged the free slew and not left the slew brake on as what had been reportly said at the time of the incident.This was a very lucky incident to happen so late in the evening and that it had no injuries as the crane had been operating for quite some time upto and on the morning of the day in question.
