Both. We had one set of rollers that rolled out in sections into the trailer that's on a large base you pin in between the trailer and the dock. The others and for all preload trailers were sections of rollers set up on a stand.
We also loaded off of those section rollers sitting on the floor of the trailer. Like in this pic. You can see it on the floor of the trailer buried under all the packages. Yeah, that guy sucked at pick off.
View attachment 247277keep in mind that's not my load. Nor is it really a load at all. I seem to recall him getting a warning letter over that one.
Anyway, now I'm in maintenance in a hub with automated sorters and full length extendo loaders and unloaders that extend the full 53 instead of some
ty 6 foot roll case sitting on the ground. I could not have less pity for the people in the hub or on this site that cry about inane
that makes their job "hard".
