Calculate Beam

[Byggare och renoverare]

Hello
I am planning to use a upe 120 beam to lift an object and need help calculating how much it can withstand. Upe 120 and a span of 180cm with the lift point in the middle of the beam.

Thanks in advance

A bit difficult to say anything without knowing the quality type of the steel. U-beams have different load capacities depending on whether they are mounted "lying" or "standing". Easiest would be to ask the person who sold you the beam.

Jo is not possible to ask, lying down it becomes used and the question is really if it can withstand being lifted 500kg in.

Oh wow! Who can lift that? But seriously, it might bend if it's not 355 steel and you lift at the ends. If you can lift 60cm from the middle, it should manage even with 235. But then we're not talking about any dynamic loads. Isn't it just a matter of testing otherwise?

Lift, move, and repair houses during the day so the lift is not a problem, turned to this forum for a calculation on a beam that I already have and want to lift/hang 500kg at the middle of 2m, i.e., 1m. Old man guesses and mockery are discouraged.

Well it's not possible to ask, it's going to be used lying down and the question is really if it can withstand lifting 500kg in it.

Are you going to load it over the z-axis, you mean? Over the y-axis, 500 kg is not much.

What are your requirements? Should it be safe? How safe? How are you lifting? Should you be able to feel secure in the equipment if something goes wrong? Or are you lifting something insensitive in a private capacity where the lift poses no risk of personal injury or major material damage?

If you need a "paper" certifying that this will suffice, you should purchase a service, which will be very expensive. The cheap version is to search for something like a beam deflection calculator and input your data; you probably (rough guess) want to keep deflection under maybe 1:500 or 1:1000. More checks should actually be done, but if the deflection is that low, you should have a fairly gentle stress state, but you do this at your own risk, and I take no responsibility for it.

The best and most serious option is to find a properly rated lifting beam for this.

In that case, don't you know from experience if it will work?
I know you can lift a whole elk with two nailed together 2*8 with 4 meters between supports and therefore wouldn't hesitate to put the chain hoist in a sling around your beam and lift 500kg.

I myself know that you can lift an entire moose in two nailed together 2*8 with 4 meters between supports and would therefore not hesitate to put the chain hoist in a sling around your beam and lift 500kg

It's about a tiled stove approximately 140cm high that needs to be lowered from the 2nd floor to the 1st floor, and therefore I want to be 100% sure that it will hold as I only have one chance.

If you need a "certificate" to prove this is adequate, you should buy a service — it'll be super expensive. The DIY version is to search for something like a beam deflection calculator and enter your details; you'd probably (guessing) want to keep the deflection under maybe 1:500 or 1:1000. More checks should be done, but if the deflection is that low, you should have quite a mild stress condition, but you do this at your own risk, I take no responsibility whatsoever for it.

The best and most serious option is to find a properly classified lifting beam for this.

Requirements are obviously that no one gets hurt and nothing breaks. Lifting with a chain hoist and it's in my private house, so it's at my own responsibility and risk.

Over the z-axis, I think it will become unstable otherwise, or do you have a different opinion?

Just for decoration? If you are going to move a tile stove, it still needs to be reset and pressure tested before you can fire it.

 

[Byggare och renoverare]

Only for decoration? If you are going to move a kakelugn, it needs to be reassembled and pressure tested before you can use it.

Does not need to be reassembled since it stands on its own frame and feet and can therefore be moved. Of course, it should be pressure tested.

Does not need to be reset as it stands on its own frame and feet and can therefore be moved. Should of course be pressure tested

But this had nothing to do with the calculation of the beam

Do you have written confirmation of that from the person who will approve the installation? If not, you might have to reset the oven..
