It’s quite common for a really heavy load to have one or more push trucks behind it to push when going up inclines. Push trucks are commonly used on the Dalton Highway as well as the Parks and Richardson when the loads are outrageously heavy, otherwise it would take a very long time and so much fuel for the truck with the load to get up a mountain, and it would also impede traffic for long periods of time. The push trucks just follow the load when not going up hills.
Taken 11 years ago, these photos really show how close Jack’s push truck gets to the load he’s pushing (a crane). You can see the pad that the push bar pushes against, how the trucks make contact.
A few years ago Jack and some other truckers took these pipe rack units from Fairbanks to Alpine, an area of Prudhoe Bay owned by Conoco-Phillips. You’ll see the units being loaded, then Jack driving behind other units. You can see the pipes in the middle of the structure as well as the valve controls on the top. These units are lined up next to each other and connected as part of the process of extracting oil and getting it into the pipeline to go south. In one of the ice road photos you can see a pipeline on the right.
They drive through tundra, over mountains, and finally on the ice roads of Prudhoe Bay. The last couple of photos, the ones where the road doesn’t look particularly icy, they are passing over a river. If you are also rather astute (and here I am giving you a clue) you can also see Jack’s reflection in the mirror, as well as a reflection of the small fan that he had mounted on the dash that could turn toward the windshield to defrost it or toward him on hot days.
