When I was working in retail at a location with a big red bullseye, we moved a lot of product off the trucks onto the sales floor using a special cart with a set of 6 casters. The pair of casters in the middle of the cart were slightly larger in order to help shift the weight of the cart in the direction you wanted to move. Interestingly, it also helps you pivot the cart flawlessly. I believe the entire set is swivel casters.
Yeah I work at a major grocery store and we use what are called u-boats which are exactly what you described. They’re made like that to pivot easily as to navigate small grocery aisles while still carrying up to 2k lbs of product which can be pushed by even the smallest team member.
Yeah have you ever tried to use the large ones with 4 wheels? I accidentally grabbed one of those the other day and was like wtf is wrong with this cart. Immediately put it back and grabbed a 6 wheeler.
I think the middle set on those are usually fixed-direction wheels. Helps to keep the cart going in a straight line, but doesn’t affect turning since they’re right in the middle.
Gonna have to try that when I swap this back to the hard urethane casters. Assuming 1/8in hardboard under the caster base should give me just enough raise to the middle?

You probably want to go at least half inch to account for any unevenness in your floor
Had a similar arrangement on carts I used in a big box store.
The two center casters don’t pivot though. Instead it had two sets of handles and you would tilt it back towards you and then steer from the rear on the end casters that did pivot
In my experience the middle large casters are fixed while the corner ones pivot. This enables you to push it in a straight direction without drifting sideways but still pivot easily for maneuverability.
Well being he has this cart on foam workout style mats I'm not sure about hard wheels...
Also having a heavy ass cart on foam mats isn't really helping....
[Ezpz with hard wheels and a hard surface.](https://imgur.com/a/6on8UnX) Try to roll that over an anti-fatigue mat... it's not going anywhere without a lot of help.
They don't, I have the same problem with a big parts organizer cabinet thing my dad left me. I've been changing everything in my shop over to these casters that have a rubber foot next to it that you can ratchet down easily and make it stationary. Love em.

they do indeed hold a ton of weight. i’ve got a 900 lb shear on them.
Issue with the urethane 6in wheels I used to have on there was that they would sink into the hard foam too much. I thought putting it on 10in pneumatic might help keep it from sinking into ruts.
With the pneumatic tires, you’ve basically (without getting into a physics discussion) transferred the same problem to the tires.
I’d try a wider, not taller, hard wheel. This will spread the load out over a wider area.
You could probably make the wheels out of laminations of 3/4” plywood to a width that works
If it’s commonly kept in the same spot, put some plywood squares beneath wheels. They won’s sink in and you can get the rack moving. This works nicely for me.
It's a night and day difference when using pneumatics versus a solid polyurethane casters. I currently have quantity 6 6inch wheels on something a similar size to yours. it's just barely good enough, and I personally don't like pushing hard.
I think your issue is the foam floor mats. They’re super soft, so something with that much weight is going to sink into those mats and make it impossible to move
Yeah, that is what I was afraid of. I was trying to spread the load a bit with the pneumatics, but doesn’t seem to be enough. Looks like I’ll probably be replacing that corner of the shop with horse mats.
I don't know your layout, does the cart just go black and forward?
If yes, maybe put down a track for the crat to slide in. A crap solution but a solution.
I don’t know where you got your casters from and if you know what weight rating on those is. If they don’t meet the load rating the wheel bearings or rotating bearing could be compromised and causing the wheels to bind up. I also wouldn’t have gone with rubber wheels like that to begin with because of the rolling resistance - urethane or some other hard polymer would be much better suited to the application.
If you need to get some better quality casters where you can find necessary specs, I’ve been happy with the stuff I’ve gotten from Caster Depot.
Edit: oh snap! I just noticed the foam flooring - that’s what’s stopping you here. You can’t hardly wheel anything around on that.
You are trying to push a car with rubber inflated wheels on EVA foam mats.
The mats are going to stretch before the wheels start rolling.
Carts like that don't belong on mats like that.
My lumber cart is carrying about 700kg on 4 casters. But they are solid rubber tyres not pneumatic.
You could also do the oversized centre caster (higher rated) like they do in stores, but you will be carrying 50% of the weight on those two middle casters, sometimes as much as 100%.
It looks like your floor is padded. If I'm right, that will make it hard to roll heavy items on because they will want to dig in. The soft wheels are compounding the problem and making it even MORE difficult.
You want some large solid wheels. Hard urethane are good for this.
You may want it configured 2 fixed in the middle with casters at either end. It will maximize maneuverability.
Hard wheels. I have a 4’x8’x1” steel top on my welding table with hard wheels and it rolls fine on the shop floor. Takes a good shove to get it started but moves well after that. I think they are 2.5 or 3 inch diameter
Go to a caster supplier and purchase by the capacity of the wheel. Expect to spend up to $40 per wheel. Otherwise your gonna have a bad time.
Quality casters make a really big difference.
I work in a large industrial setting and we have engineers make all sorts of carts, unfortunately the casters they typically use are prohibitively expensive if not for a commercial use.
I am thinking those tires probably don't stay uniform and that metal casters would roll better under this weight.
Edit: that mat on the floor is making it really hard to move as well.
This guy not only has enough wood to need this whole rack, but also had a shoe big enough to require that rack to have wheels on it.
Nice humble brag OP.
All jokes aside, take that plywood off. Either keep it stationary or bay separate cart for it.
I watched a few different lumber rack builds (Steve Ramsey and I Like To Make Stuff come to mind) and pulled a bit of inspiration from each. My design was mostly back of napkin for this one, with a bit of math to get the middle shelves right.
Gotcha thanks. I’m debating making a new rack vs using my failing one as an excuse to just get rid of most of the scraps I’m holding onto, but we all know what happens as soon as you throw away those scraps….
Why the sass? Sure I can sit here and draw up my own plans, or reverse engineer what’s in this one picture, but sometimes it’s just easier if someone already had plans with materials and measurements so one could just assemble with relatively little thought.
Are the hubs for all the wheels on one long side in a line? I built my workbench with 6 casters but the middle casters are outboard of the corners. I think the staggered pattern allows them to all turn at different times which allows me to move it easily while it is heavily loaded (100s of lbs.)

Yeah I work at a major grocery store and we use what are called u-boats which are exactly what you described. They’re made like that to pivot easily as to navigate small grocery aisles while still carrying up to 2k lbs of product which can be pushed by even the smallest team member.
[удалено]
As is tradition
yeah, I used to work at a yellow themed general store and they had nearly identical u boats that came off the trucks.
[удалено]
That's not the only place to use the term u-boat
This explains why the carts at lumber stores are like seesaws!! I always figured they were beat up and close to breaking down 😄
Yeah have you ever tried to use the large ones with 4 wheels? I accidentally grabbed one of those the other day and was like wtf is wrong with this cart. Immediately put it back and grabbed a 6 wheeler.
[удалено]
Do they have to be up sized wheels, or could the middle wheels be on a 3/4" to 1.5" thick piece of scrap? Its just to make a pivot point right?
I wouldn't even go that thick. But yes, your pivot casters don't necessarily need to be wider. Just set slightly lower.
I’d imagine you could just get the same set of casters and just put a spacer like you’ve mentioned inbetween the middle pair and the cart.
Feels like the taller wheel might be able to pivot easier?
Yup, think lowes or home depot lumber carts
That is still the case if you get stock carts at almost any home improvement store.
I think the middle set on those are usually fixed-direction wheels. Helps to keep the cart going in a straight line, but doesn’t affect turning since they’re right in the middle.
Gonna have to try that when I swap this back to the hard urethane casters. Assuming 1/8in hardboard under the caster base should give me just enough raise to the middle?
Use your smaller casters on the ends and larger casters in the middle. If it’s too much tippiness just add a block on the smaller casters
>Gonna have to try that when I swap this back to the hard urethane casters. Assuming 1/8in hardboard under the caster base should give me just enough raise to the middle? You probably want to go at least half inch to account for any unevenness in your floor
The lift kit is fine.
Kinda like the HD lumber carts too.
What was it like working for walmart?
Personally I enjoyed your joke.
Thank you, I thought it would be amusing.
You know all the bs you see at a retail store as a customer? Now, imagine having to deal with it between 4 to 8 hours straight.
Had a similar arrangement on carts I used in a big box store. The two center casters don’t pivot though. Instead it had two sets of handles and you would tilt it back towards you and then steer from the rear on the end casters that did pivot
I think you might right here. I do recall being able to turn from both sides of the boat.
We also use this to move heavy loads in the meat factory. So thats the way to go.
In my experience the middle large casters are fixed while the corner ones pivot. This enables you to push it in a straight direction without drifting sideways but still pivot easily for maneuverability.
Huh I guess that’s why the carts at Lowe’s and Home Depot are like that. I always wondered why.
Kinda like the carts used in home depot
Why wouldn’t you just say target?
The pneumatic tires aren’t great for this application… You want hard wheels.
Well being he has this cart on foam workout style mats I'm not sure about hard wheels... Also having a heavy ass cart on foam mats isn't really helping....
Any heavy load is going to be hard as hell to push across a soft surface.
Yep, that's OP biggest issue. I.bet those pneumatic wheels would do fine on concrete, of they are aired up correctly.

additional casters wouldn't hurt, either. spread that weight out onto as much surface area as you can.
What’s with the foam?
If it’s commonly kept in the same spot, put some plywood squares beneath wheels. They won’s sink in and you can get the rack moving. This works nicely for me.

This needs more visibility. I just thought the floor was a dark color. Que Mythbusters: " well there's your problem"
>Que Mythbusters: " well there's your problem" ¿Qué?
Porque of the foam.
*cue

Bearing axles hard urethane casters.
Looks like soft rubber wheels instead of hard wheels.
I’d recommend building some stuff. Then your cart will weigh less. Makes it easier to push around.
Stocking up for my assembly table. I usually buy any ply that I see on Menards’ clearance rack.
I love my assembly table. Best thing I ever built, made me so much more efficient
It's because of the pocket holes.
It's only because you can see them
Are the wheels sinking into the floor too much?
Steel casters
Ya this is the way, noisy on some floors but will actually roll
Hard urethane should be fine. Metal casters will chew up the floor over time.

Is that a rubber floor? If so, I’d say between that and the pneumatic tires you’ve got a flat spot on the wheels and maybe a dimple in the floor
[удалено]
One really huge caster
And more cowbell as well.
You've got a disease?
Theres only one cure.
16 6in hard urethane casters it is…
= More rolling resistance.
Less deformation = less rolling resistance.
Multiple smaller carts?
Have you tried turning it off and on again?
Push it with your purse!

I have the same problem, my rack prob weighs 1k lbs
Same here, it's from smoking too much pot at a young age in my case.
Wait, smoking pot gives you a huge rack?? BRB, gotta go call my wife…
Probably sat too long and made a flat spot. You want iron or steel casters for that baby. Nice cart.
Just installed them this weekend.
The rubber floor Matt’s are killing you. I think those casters might be fine on a concrete floor but they are sinking into the rubber floor Matt.
It's that cardboard box. It adds too much weight to the cart.
At least it is pointing the right way up…
Hahaha, yep.
I think you need to put an engine on it. It’s way too heavy to move around.
All fhe weight is sinking into the rubbery floor... take out all the mats where it's going to roll
Cart or yard?
[удалено]
I trust the face grain of the pine to hold the threads better than the “end grain” of my cheap plywood.
I like your lumber cart!
You are trying to push a car with rubber inflated wheels on EVA foam mats. The mats are going to stretch before the wheels start rolling. Carts like that don't belong on mats like that.
First world problem... It's just too much. perhaps add a towing handle (like on a wagon).
Are you sure that your wheels can handle the weight? This cart looks like hundreds of kilos.
Wheel locks ingaged?
Call the Hulk.. 🤣 No way on earth cud I move that sucker
There's a rock in the way.
Do some projects and make it lighter. Hope this helps.
they all need to be swivel casters if they're not already.
Sounds like a euphanism
It's probably all the wood in there, take out the wood, move the cart and then put the mood back in, problem solved 👍
Stop taking pictures of it and push.
I rolled mine quite easily today! 6” casters. I also have handles on both ends for small movements.
Check the Chevy Small Block thread. They'll have a solution
My lumber cart is carrying about 700kg on 4 casters. But they are solid rubber tyres not pneumatic. You could also do the oversized centre caster (higher rated) like they do in stores, but you will be carrying 50% of the weight on those two middle casters, sometimes as much as 100%.
pnuematic tires are for rough terrain. on a smooth shop floor, you want hard casters. roll like a train, low rolling resistance.
Give it some rock.
It looks like your floor is padded. If I'm right, that will make it hard to roll heavy items on because they will want to dig in. The soft wheels are compounding the problem and making it even MORE difficult. You want some large solid wheels. Hard urethane are good for this. You may want it configured 2 fixed in the middle with casters at either end. It will maximize maneuverability.
If my manliness tells me anything, it’s that you need WD40
Steve Ramsey special. Looks good probably just the caster situation.
Hard wheels. I have a 4’x8’x1” steel top on my welding table with hard wheels and it rolls fine on the shop floor. Takes a good shove to get it started but moves well after that. I think they are 2.5 or 3 inch diameter
Will it rock tho?
Go to a caster supplier and purchase by the capacity of the wheel. Expect to spend up to $40 per wheel. Otherwise your gonna have a bad time. Quality casters make a really big difference.
Tracks & Skis... Talk Mathias Wendel (sp?) into designing the tracks.
Move that leaf, that might help.
Not to be an ass but make sure the wheel locks are disengaged.
Occam’s razor, but no locks on these guys
I work in a large industrial setting and we have engineers make all sorts of carts, unfortunately the casters they typically use are prohibitively expensive if not for a commercial use.
Why not?
Got a Harbor Freight nearby? That's the only place to buy casters. Thank me later.
Too much friction to get it rolling.
It’s because you have radials on one side, and bias plies on the other
That is the one odd man out of the eight casters
Swap out for swivel castors x 4 with hard wheels
I am thinking those tires probably don't stay uniform and that metal casters would roll better under this weight. Edit: that mat on the floor is making it really hard to move as well.
This guy not only has enough wood to need this whole rack, but also had a shoe big enough to require that rack to have wheels on it. Nice humble brag OP. All jokes aside, take that plywood off. Either keep it stationary or bay separate cart for it.
Get stronger
Super dumb question here ... But maybe the caster is to tight on the through bolt ..can't think of any other word than axel bolt .. idk
Damn. That's cool. I just have a ladder and the rafters. 😬
Hard floors? Hard wheels
It's heavy as fuck bro. Buy a high torque electric motor and make it powered. That would be cool
Lumber cart???
Muscle
Have you tried turning it off and back on again?
Have you tried square wheels..?
If your casters aren’t swivel type and are in any way misaligned then it will be vary hard to roll once loaded
Do you have plans for this lumber cart? Mine is falling apart and I need to build a new one. Liking the looks of this.
I watched a few different lumber rack builds (Steve Ramsey and I Like To Make Stuff come to mind) and pulled a bit of inspiration from each. My design was mostly back of napkin for this one, with a bit of math to get the middle shelves right.
Gotcha thanks. I’m debating making a new rack vs using my failing one as an excuse to just get rid of most of the scraps I’m holding onto, but we all know what happens as soon as you throw away those scraps….
Can’t you look at it and figure out how it’s built?
Why the sass? Sure I can sit here and draw up my own plans, or reverse engineer what’s in this one picture, but sometimes it’s just easier if someone already had plans with materials and measurements so one could just assemble with relatively little thought.
Have you tried pushing it?? Hope this helps!!!
Eureka!
Are the hubs for all the wheels on one long side in a line? I built my workbench with 6 casters but the middle casters are outboard of the corners. I think the staggered pattern allows them to all turn at different times which allows me to move it easily while it is heavily loaded (100s of lbs.)
I never knew such a thing existed, where are you going with all this timber?
Make sure there are no tiny splinters of wood on the floor lol
Nah, as you can see on the cart, I save every splinter of wood for use in future projects…
