I have two concrete slabs that are 4'x6'. How can I move them?

Can you get some round pipe underneath that can take the weigh? Roll it one pile width then take the back one and put it in the front. Not sure if it will work but it's an idea.

Good luck

Rollers! If can be lifted a few inches get some strong guys and put some rollers under width of slab. Start rolling towaed where want it and keep moving the rollers as you go. Once its where you want it remove rollers. (Rollers can be large logs,just try to have them all be same size for easier use and wont be tilted.

I needed to move some large railroad ties by myself. I was able to lift them enough to put two old galvanized pipes under them and roll them into place. As you roll off the first pipe, place it in front of the slab of concrete and roll onto it, progressing to the end of the driveway. Lots of work but worth it!

Two mechanics creepers (heavy duty) would work.

How about renting a fork lift or skitser

It is important to know the weight of any section of concrete that is being cut. The weight of concrete is approximately 150 pounds per cubic foot, or 4,050 pounds per cubic yard. The formula for calculating the weight of concrete is: Length (in feet) x Width (in feet) x Thickness (in inches) /12 x 150 = weight (in pounds).

Overestimating the lifting capacity of any piece of equipment is likely to occur when the rigging provided for a job is insufficient in size. Using undersized or incorrect equipment for a lift causes a substantial number of accidents.

Your slabs are approx. 1064 lbs. each

It would take 3 creepers to put under one slab at that weight and that's if you had heavy duty creepers that would support 450 each. Check into a manual pallet truck. I don't know if you can rent them or not. Please be careful whatever you decide.

If you know someone with a good pick up truck you can use ropes, towing straps and drag them the distance. The pick up should be able to get around them once their moved.

I'm thinking of the way the ancient Romans, etc., moved large stones. Get a bunch of round wooden poles (the thick wooden closet rods, they're pretty cheap and come in various lengths). Put them on ground, lift edge of concrete onto them, spaced a bit apart. Then roll the slab forward slowly. As the ones in the back become exposed, pick them up and put them in front of the slab, rolling forward onto them, and so on. This will be tedious, but if you are patient, you will get the slabs moved.

Certainly worth considering if the other options don't pan out. But it sounds like lots of sweaty work here in JawJaw in July.
