In the a couple of years, I am going to have to figure out how to move a
1500 pound machine into a closed truck. There are no anchor points in the
truck that can take the load, and it will be going up a ramp in order to get
into the truck.
Right now my concept is rollers (how I moved the machine last time - 2"
thick dowels I turned out of firewood), some sort of choc/wedge anti
back-roll, and a long lever bar. Walk it up the ramp in little steps using
the lever bar between the ramp and the bottom of the skid - lift, chock,
reset bar, continue.
I've lifted large boulders uphill in a similar fashion, but they don't tend
to roll back down the ramp....

There was an excellent program on UK TV concerning the erection (not
casting) of Abraham Darby's Iron Bridge.
Short version - A frames and rope.
