Here we needed a super strong pivot so we used one end of our bud axle to put on our trailer for Poochie to be able to load and off load tire at his will. We have a 1250 pound electric winch to lift the tires.
Works super. Super Design.
Here you see the complete assembly that turns 360 degrees. We can carry 8 tires on this trailer at 520 lbs each. They ride on 34x10.5x16 aircraft tires that have not had a flat in 7 years. They are 14 ply.
