Just hope that there isn't a small leak in the barge, as they can list to one side quickly. Good friend lost his entire sawmill in the Mississippi river when loaded on a barge and it took on some water. Happened in matter of seconds.
Thanks for posting. Kinda like the one where the guy loads the bobcat (skidsteer) on to the truck bed.
Tips it on its nose, backs up to the truck bed with the rear wheels just on, and then lifts the front wheels off the ground using the bucket as the back wheels move onto the truck until the front wheels are on. Either the truck is backed up or in neutral to move a bit.
