About 15 years ago one of my extruder projects was delayed for several weeks when the manufacturer managed to drop the extruder they were building for us about 10-12 feet. One of the lifting straps failed as the completely assembled extruder, that had been fully tested, was being moved into the paint shop for painting prior to shipment. As the strap failed, the extruder dropped onto the 600 Hp motor smashing it and continued to roll over onto the gearbox damaging it. I was told that the extruder went through the 8" concrete floor of the shop. Fortunately the shop was on a slab so there was nothing below it that could have been hurt.
A few years later while working for a different company on another extruder project, the moving contractor dropped a different extruder, while transferring it from the cargo aircraft to the truck. This extruder was smaller, only 300 Hp.
I haven't done any extruder projects since then, I think maybe I'm jinxed or something.
