What did you do TO your Gladiator today? [ADMIN WARNING: NO POLITICS, NO GUN TALK]

[ShadowsPapa]

Why would suspension, brake, engine, etc. work not work with a 4 post and two 4 point trolley jacks to take the wheels off the platforms?

Concrete is my other reason for liking 4 post. No way to be confident in strength without pouring footings. Core samples can test sections, but if the pour wasn’t consistent, you’re just hoping with your life at stake.

Yup - that concrete slab has to handle a lot of stress, and not all straight down with a 2 post.

A bit part of the reason for thinking about 2 post originally was - SPACE. It was quite a deal making room in my shop to get my JT into it! It's a mess in there, things had to be shoved around to make room for that truck and have room to walk around it and work on it.

Don't use wedge concrete anchors either. They will pull out. Best is when pouring your concrete. Have your bolting in place. Use a J-type anchor bolts

A heads up for anyone planning on getting a 2 post lift. Before you buy. Look at the concrete requirements for installation. Have a friend going through this headache now. His concrete guy did everything right. The thickness, the psi of the concrete rebar, etc.. The problem is where the seams of the concrete are. When they started to install the posts. Found out that they are too close to the edges of the slabs. So now he has to cut the slabs, and dig down deeper, about 4ft. The posts will have their own foundation now.

Have 2 friends with 4 posts and they like them. You can do about 95% of the stuff as a twin post with them.

A big reason I think four post will be the way I go.

Absolutely ideal. Tough with existing slabs though.

The problem with that is - at least here - unless you keep the shop heated at all times through the winter, it's possible the main slab will heave or lift with the freezing ground while the footings for the posts will not. It's an issue I have where the approach at my shop has done some rising and falling, as does the slab under the lean to, but with the shop constantly heated, the ground below it never freezes so the floor doesn't heave or lift due to frost in the ground. I was warned when the new approach was poured - it can NOT be anchored to the shop floor in any way - things will break.

Not to discourage you, but put some thought and research into this.
Transmission jacks usually come in 2 sizes. One for doing the job on the floor and the other is for doing the job about 6 ft in the air.
I've used both, and there are pros and cons to each.
I've never seen one that would work at 3 to 4 ft. Not saying they aren't out there.

There is a nice used 2 post on Facebook for $2500 right now. Seems like there are deals on used ones some what regularly. Just a thought on another option to save money.

Great point. I’ll be selling my gantry crane, almost certainly, because I don’t think I can fit both. Anyone that wants to come get it will get an indoor stored crane in brand new condition. And when I say indoor, I mean my living room.

Very very true.

Haha, I remember the pictures.

It’s still there. One more 350-400lb fire pit to get upstairs, then the dreaded disassembly.

LOL - no way I can get a gantry crane in my tiny living room. In fact, mine won't even make it through the doors.

It was originally engineered/made/used for lifting sprint cars onto trailers.

I couldn’t have either. I assembled it new in the living room. It took my aux winch from the Jeep to even get the parts up the back deck stairs. And three people to tip it upright after I assembled it. I know I’ll regret this someday, but maybe not. Good memories of craziness.

Installed a Amazon special Trail Rail System today. Kept my expectations pretty low before receiving it but was pleasantly surprised as it seemed of decent quality with decent hardware. Chased the threads in the bed because of the bedliner material but everything installed easily with decent fit and finish.

Just added that to my Amazin cart cheapest I've seen anywhere. Great find.

With a total square footage of about 950-1000 for the whole house, we'd have to move out some furniture, knock out some walls. Mine is welded construction then powdercoated after it was welded together.

I forgot to comment on how cool the chain hoist is. I love old tools. I still have my grandpa’s old chain hoist. I’ve got some great kid memories lifting unreasonable things with it, like 1,000lb lengths of flat steel to reinforce an I beam to remove a basement post. I still have the c clamps we used to hold it to the beam while we drilled 3/4” holes and through bolted it. Not as strong as yours I’m sure. Mine will do two tons.

The gantry crane itself will lift a whole sprint car straight up - but the seller kept his chain hoist so I bought this one - good enough for my use - it could lift my SX4 (minus the drive train) up so I could slide the engine and drivetrain under the car and install it all as a unit from the bottom like the factory did.

I have an engine hoist, too - people call a "cherry picker" although I don't know how it would help in picking cherries........... I made that one from plans in a Popular Mechanics many decades ago. It doesn't fold or some apart and takes a ton of space in the shop but it works well for my uses.
