I know a lot of you live on, work on, or have knowledge of cattle farms. I'm looking to build my own portable alley. Have most of the details worked out, but I havent been able to decide on the easiest way for me to get the wheels under it and ready to roll. I've seen examples with hand winches, electric winches, hydraulics, lifting with a bale bed or tractor and rolling a 1 ton axle under and pinning in place, and a setup with telescoping square tubing that slid down when the alley was lifted. Then a pin put through the tubing to keep it from dropping. I thought the square tubing was pretty slick, and easy to duplicate, but you need a truck with haybed or tractor on both ends of the trip.
Any ideas, opinions, and pictures would help a lot.
