That vid has been out there a while . Looks like typical Big boss was in a hurry job . Before you trash me just look at that whole deal . The break over on the hill was way too sharp . There were axles over loaded and some with nearly nothing on them . That's the momentum and excess speed . There was a decision to not trim the point of the hill .
There apparently wasn't anything worked out for control or the driver with the boom section wouldn't have been in the way along with the guy on foot watching the white trucks left front corner . What about the guy that runs ahead of the truck and places himself between the two trucks . the driver with the crane had his hands overloaded and now he has 2 guys on foot in front of him in a total panic situation .
But the key thing that lets me know this is a result of poor management and cost cutting its the simple fact that machine is multiple pieces . If I recall the upper half is 4 pieces and the lower half is 3 pieces .
Time spent and 6 or 7 extra loads would have been way better than this youtube vid enshrined on the net forever .
