Sounds about par for the course
Sounds about right. A while back, DUB needed a second main deck, so a veritable pile of scrap was shipped in from a UK station, at phenomenal cost. It was so bad, it had to be lined up about 9" offset from the door before the jacks were put down, and then when they were, it would tilt that much, and if you got it right, there was a chance it would be aligned. That's aligned laterally, by this stage it wasn't level, so if one edge of the pallet went over the gap nicely, the other edge was either 6 to 9 inches or more above or below the cill, depending on if it was an off load or on load. That tended to cause problems if the pallet hadn't been built too well, an edge dropping that far, or the pallet flexing that much can cause embarrassing consequences!!!
I spent the next 6 months reporting it at least once a week because the overload alarm was going off because the main deck and lift deck went out of alignment whenever a pallet over about a tonne was put on the thing, but nothing was done. It was always a case of "it's working, and we have to have it on the ramp", so the defects were deferred in a way that was typical of so much at DUB.
The 2 A320 loaders may well be narrow ones for the 320, if they're anything like the one we had at DUB, they are a pain, as each bin has to be turned manually to get it on to the loader from the dolly, which is not a lot of fun, and it's all too easy for non experienced people (most of them<g>) to end up dropping a bin on the floor.
