Griff is probably correct. RC crane operation is increasingly the standard. The unit is usually something a bit smaller than a shoe box, worn on a belt apparatus, leaving the controls at comfortable waist operation height.

If you look closely at the zoom shot third from the end, where the white car is being lifted by the larger truck, you can see that same guy (although he looks more blonde on my monitor) with his back to the camera. It appears that he has a grey strap running below his sweater line, which is probably the control unit belt.

I'm really curious as to what the hell the operator of the first truck was thinking. It appears that it was operating waaayyy our of parameters. I see no outriggers on it to begin with (the reason it went over)... In fact, it looks like the bed is a RO/RO (roll-on, roll-off), making me believe that the truck and it's arm were more designed for short reaches and straight-up lifts onto the bed.

I also wonder if the Brit (it looks to be Britain, anyway) pollution regs are as stringent as ours, because you can see tens of gallons of diesel pouring out of the first truck as it goes over the side. Probably mucked up the water in the quaint little port for a bit.
