Need a gantry crane for a one time use.

Stupid electric truck driver trying to get a free charge!

Blimey . when they say "rigid body" they aren't kidding ay ?

I wouldn't even have thought it possible without it snapping or massively bending.

I did find a really cool rock over the weekend.
It is black granite, with veins of white and pink running thru it.
It has one very flat side that will be the bottom. That bottom is oval shaped and about 30 x 55 inches.
The whole thing tapers up to a point that will be around 60 inches high. All of the veining will be vertical. The sides are as fractured out of a wall of granite, nice and jagged with razor sharp edges. The guy at the quarry estimated it at around 7,000 lbs. I will pay them to deliver and set it. No way I can or want to handle that much weight. Of course the one I picked is in the middle of a big mountain of other black granite boulders where this is one of the smaller ones. They have to dig it out and weigh it to be able to et me a price on the rock and the delivery. I will still have the option to decline if the cost is to high. I also have no idea what the other side looks like. It might be butt ugly on the side I can not see.

Being 5 feet tall it will not disappear from view as a car gets close to it.

I did take some pics of it in the pile but pics are very hard to see what it really looks like. You will have to wait to see it in place if I end up getting it.

I do have a second choice at a different quarry but it is not nearly as pretty.

The quarry did hove one big chunk of pink granite that they would sell me real cheap just to make it go away. But it is around 10 TONs, ie 20,000 Lbs. I would have to hire a crane to load it on a lowboy semi and then another crane to unload and place in my yard. That one will stop almost anything that can make it down the alley.

Now that sounds like a solution that will work.
1. Will be effective
2. Will look nice
3. You don't have to move it
4. will be visible to drivers
 
Making progress.
The rock has been dug out of the pile and weighed, It is 5320 Lbs.

It is on its side in the pics and a bit muddy.

Now the FUN begins......

The quarry wants $400 to deliver the rock. That is just to drive it from the quarry 27 miles to my house. Does NOT include unloading or placing.
I found a landscaper that has equipment to handle this size rock that will do it for $250.

So I figured I would rent a flat bed trailer rated for 10,000 lbs and transport it myself. I have a full size 4x4 pickup. Trailer is $75/day, should be an easy one day job. But then the fun starts. The trailer uses a 2-5/16 ball. My old 2-5/16 ball is only rated for 6,000 lbs The rock alone is almost that. So there is another $75 for a new Class IV ball and mount. The nut on that ball has to be torqued to 450 Lb/Ft. Fortunately where I work they have a torque wrench that goes up to 600 Lb/Ft but no 1-7/8, 3/4 drive socket another $40.

Now I need a way to make sure the rock stays on the trailer. Ordered a set of 4 Grade 80 chains and binders. Another $275.

So I am up to $465 to save $400. but then I have a new ball and mount, and 4 good chains and binders to add to my collection of stuff.

Now we get to toss a wrench into the whole works, Was talking to the landscaper yesterday to set up an time to do this. I told him that it would not be first thing in the morning as I have to go rent the trailer drive to the quarry have them load the rock, tie it down and drive 27 miles back home. He asked me what the trailer rental was. I told him $75. He tossed out that for an extra $50 cash he would stop at the quarry and have them load it on his trailer with the other equipment and he would bring it with him.
"Of course" I said. SO canceled all of the orders for all the other trailer stuff and went with his plan B. As Murphy would have it the chains and binders arrived today, all 113 Lbs of them. Good thing Amazon is good at taking things back.

I should be getting my new rock sometime in the first week of December. As soon as his equipment gets out of the shop. It is getting a new hydraulic pump installed, I will be his first job once it get done, but he is not sure exactly when that will be.

Fingers crossed this all comes together as planned. To many puzzle pieces that I have no control over.

Glad we could help:laughing::laughing:
 
I'm thinking this rock might pay for itself over time.
Rig up a trail cam somehow so that it takes a photo if it gets bumped.
Then when someone hits it, you'll have evidence and can put a claim in on their insurance company for damage to your rock - say a couple Hundred $ each time it happens.
