Thanks!
I'll take a stab at this. The first pic is looking under the gooseneck of a lowboy trailer. The second pic is the front of the gooseneck, sitting on the hitch, the rollers roll up the ramps that @Chicken lights built.
Most trailers now have a parking brake. I heard years ago it was an issue without them, you’d go to unhook and the trailer would take off on you. Or worse if it was icy you’d spend all afternoon chasing the trailer around the yard, trying to pin up to it
The “toothy thing” is my fifth wheel riser. I can slide my fifth wheel and the teeth are where it would lock, in different positions
Pretty much. I generally don’t move mine but that’s besides the point
Just to add....When you unhook the air lines, All modern trailer air brake pots(since the early 70's) dynamite the trailer brakes automatically. I had my tractor leased to another trucking company, pulling their trailers, The trailer repairs were up to them to keep them roadworthy....they became very lax in this and I was constantly complaining and doing my own repairs to remain safe on the road....until one time I watched the boss unhook his trailer and it rolled away from the tractor on its own, there was not a whisper of brakes left on that trailer. I filed an official report to the peat moss company ( the same company, by the way, that hired the truck that hit the hockey team many years later) but that was ignored so I had to go to the Provincial Highway patrol next...all the trailers were seized within 24 hrs.
You’ll never believe me.....
