I made this so I could load goats alone but I no longer need it. It comes apart into four pieces and can be assembled by one person.
The ramp has a metal frame but older plywood so it may need replaced. Don't know what the max weight would be but it holds a 130lb person and several 50lb goats just fine.
All of the lumber is treated and it is assembled with exterior screws. It uses drop pins and pockets from Northeast Gate Company and the sides can also be screwed in for extra support.
I can get exact dimensions for serious inquiries but it is made to reach the tailgate of a standard pickup.
Has been stored in the barn. Prefer buyer pick up.
