Do you mean a regular ramp or a set of ramps like you use to change your oil? The former,No The latter i have used in a pinch to load a car on the trailer.I had thought about building a set of permanent ramps at the shop so i could just back up to them and load/unload the race car.My thinking was i could use it as a oil change rack as well. May still do this when we build our house/Shop
folding ramp that can hold up to 10k.... not that you could pickup and move without a forklift and be able to afford it to begin with. Would take lots of steel and steel is not cheap
Some stout spruce posts in the ground with beams on top (ie: 6x6 or 8x8) and your choice of decking (some in the 2x range) would make a great permanent ramp. My neighbour built one at his place.
