Fw: Moving 3000lbs?

["adsach" <adsach@zzzzzzzzzzzzzz>]

Adding to previous suggestions:

I would consider using an engine hoist to lift the stone onto whatever contraption/rollers you use and for the final lift onto the stand.

I bought an engine hoist (foldable) for about $120 at an autoparts store. It lifts up to 4000lbs and raises a hook about 7.5 feet in the air at the 3000lb setting.
I would take the wheels off the hoist moving anything over 500 lbs.

(Personal disclaimer: I've never moved a stone over 300 lbs)

2-3 inch nylon straps(2) give a gentle, secure grip on the stone - check the load rating. Your average 1 inch nylon strap is only rated for 200-400 lbs. You might have to go to a steel cable with wood cushioning, but straps are gentler on the stone and less prone to shifting when you apply load. Good straps and hardware might cost another $120, or more.

With such a heavy weight, make sure your hoist is always square to the forces and solidly planted on level ground. (at least some plywood under the base on a gravel surface). If the stone doesn't fit between the legs of the hoist, your hoist is too small.

If you want to use it for dragging, or lifting any direction besides straight up. You may have to anchor the base of the hoist (cable and rebar driven into the ground?) to prevent tipping.

Whatever you do, don't plan on pushing, nudging, or otherwise using your back to position or swing the stone. If you want to set the stone down several inches from directly below your hoisting hook, try 3 short pieces of 4x4. 1 4x4 to make a high side(the ground/plywood is the low side), the other 2 4x4 under the stone, so it slides a few inches when it is set down.

Now for the safety lecture:

Take your time. The stone isn't moving by itself, so you can take the time to be safe. If something starts to tip, slip or fall, get out of the way, wait 'til things stop moving, and carefully assess the situation. Pets, small children, wives, brave friends, friends with beer, dentable cars and favorite lawn ornaments should be kept well away. People experienced with the EXACT equipment make good helpers. Don't be a hero, as a big stone can crush you without pity.

My that sounded grim. Take heart, a lot can be done with simple tools. Remember that guy who is building a cement stonehenge all by himself using simple levers and fulcrums?
