That's not really relevant to this discussion. Simple case of one lift being overloaded, Tilt and surface angle bringing it un-done. But its a classic case of being on the border line. Max capacity at height with the mast tilted back. (Truck Height). As you lower it the load moves forward. (Sine of the mast angle). Then it goes arse over tit.Just don't be like these guys. I'm sure they are glad someone was there to capture the moment.
