Hello; I always wonder how this happens. I've never operated a crane, but don't you know the weight of the lift? Isn't it just math to know what you can lift or can't lift, and how far you can extend that load? Some of these mistakes must have been soooooooo costly. I just cant imagine the work required in cleaning up and repairing all the damage! I think they could've left the phrase "Dangerous idiots truck fails." As quite a few of these comments point out, this has more to do with miscalculations of operation dynamics. None of these showed a single bad driver. However I am curious why at 11:40 someone was trying to lift a truck into the 2nd story of a building? That one with the tanker sliding in the mud and turning over happens more than you know. I used to drive tankers in the oil field and have seen it happen several times. It don't take much once they start to slide and then lean on a slope. I have driven a dump truck, water truck, etc. Learned to operate heavy machinery like a dozer trackhoe skidsteer etc but I have absolute respect to crane operator's etc.
