Folding crane - scary but brilliant

i saw a folding crane years ago in Townsville, but it was a different type.

It was a normal lattice Girder crane and I hired it to pour the forst pours of a chimney at the cement works. The driver luffed the crane down and it touched a brick wall with the lowest tubular member, putting a slight bend in it. I pointed this out to the driver but he didn't think it was a problem. We finished the pour. About 3 months later I saw that it had collapsed on a construction site and killed a worker. That same tube hd collapsed in compression dropping a load of concrete and the boom on the job site. Those days of poor responsibilitty have gone now, but on my very next job in Gladstone I had a similar crane driver and sacked his company, Brambles, because they caused me too much anguish.

A long slender element in compression will fail at a low Load if it's bent at all. The Crane operator should be aware of such things  Nev

Brambles were notorious operators of equipment. In Kalgoorlie in the late 1980's and early 1990's, they used to write off at least semi-tipper trailer a week, via rollovers from carelessness and lack of driver skills.

The manager there was noted for his massively corrupt ways, ensuring that anyone he gave a job to, had to "reward" him with a carton of booze a week, for the pleasure of having been given a job with Brambles.

AFAIK, the managers corruption was never uncovered - but there's probably still plenty of corporate corruption going on.
