Default Lifting a 900lb mill without a hoist

Gents,

I'm in a bit of a bind and I'm too blind to see a solution. I'm hoping
someone here can set me straight.

I built a cart for my Hardinge TM and need to get the TM on it. The cart
is made of heavy angle and box channel, and I used 6" wide pieces of 6x8
angle for the caster mounts. The mounts ride outboard of the cart, and
the top of the mounts rides higher than the bed of the cart - by design
- so that the mill will only be 5" off the ground when transferred.

I'm trying to figure out a way to get the mill on the cart without:

1. Building a gantry
2. Modifying an engine hoist so I can get the legs around the outside of
the mill
3. Hiring a wrecker
4. Breaking any bones

Since I gave the cart a nice paint job, I'd also prefer a method that
will limit damage to the paint on the cart.

I have the mill resting on a couple of 4x4s, and can easily get her a
bit higher. Tha challenge here is how do I transfer the mill from the
wooden platform to the cart without killing myself.

I was going to build a small gantry until the price of steel went
through the roof here.

I'm sure there is a solution, but I've been staring at this so long I've
developed a brain cramp. Any thoughts are appreciated.

Here is how you do it.

1. You already have the machine on 4X4's. If they are longer than the
cart is
wide then raise the $X$'s up on blocks at the ends. Raise it high enough
that the cart
can be slid under the machine. The machine is now suspended over the cart.

2. Now support the machine by other blocks that are in the center opening
of the cart.
the machine may be unstable at this point so tie it down such that it cannot
topple over.
Now remove the 4X4's

3. Remove the supports that now support the machine and lower it onto the
cart.

Every time I move a machine I always tie it to something that can support it
if it
begins to topple or slip. It has saved a number of machines.

Another thing; I always psych my self up to run away if something goes
wrong.
This counteracts my natural inclination to try to stop something from
falling.
I have moved Bridgeport's and 1000 LBS. lathes single handled. I don't
want
help. I would never trust someone else with the all important "run away"
part of moving
heavy machines.
