Getting an RSJ into Place

Get some professional help before someone is seriously injured or killed!

naaah, three medium hefty blokes can /easily/ lift 350Kg

The raise RSJ / raise scaffold / raise RSJ / raise scaffold method sounds more than feasable but I'd have more than me + Gf around if I was doing it and I'd beef up the scaffold supports to offset any potential inclement weather.

plus, you're insured, right ?

(While doing my loft conversion, there must have been at least a ton of tiles stacked along the scaffold for a few weeks without any problem).

Using a pully with a ratchet action to prevent any possibility of it slipping sounds good. You may be able to use an electric winch with the pullys to remove some of the effort. You could also get acrows under the beam should you need to do some finer positioning once it is in place.

That is a reference size for a universal beam, and the 25 is the weight per m in kg, so your estimated weight is 100% over - 7m x 25kg/m = 175kg. Still a bit heavy to lift by hand though :-)

If its 254mm deep by 102mm wide by 25kg per meter then should it not weigh 175kg?

I would use a couple of steel tower scaffolds myself and a a trolley jack.

:) More or less. We recently lifted a 7m length of 16" x 11" oak beam into place using much the same method. Me and a labourer got it into the building on rollers and up into place in 8 hours.

Yes I am, but nott aginst stupidity !!!!

Sorted, 175kg no issues, a tractor will easily lift it, one on each end. My Bobcat can do one end, as the houe is built into a bank, its ony a 7 foot lift on one end, so I only need one tractor.

I'll get the beam a good bit too long, lift it up, scaffold under it (not a silly 4 foot steel tower, but some quality stuff) and I am away.

Thanks Rick

Thanks for the encoragment, the next question is an oak truss, 4.5 m wide. Take it slow and easy, and it will get there in the end.

An oak truss!!!! have you seen a doctor modern surgical techniques can work wonders you know Or is it for after you have lifted the beam into place?

Seriously I saw Tommy Walsh put a large oak beam in on the TV and the scafolders that built the frame they left the horizontal poles the beam was resting on loose to act as rollers . Obviously there were other horizontals below these to stop spreading

Reminds me of getting the 4.5 metres 9x2s in for our loft floor only way short of taking the roof off or tearing down ceilings was to remove the air brick/ vent from the back bedroom chimney breast, remove corresponding bricks from the outside (luckily house was built with lime mortar so an easy enough job ) and them lift them onto the outhouse roof and feed them through the hole.bedroom, down the landing and thence into the loft

An expensive way might be to have it cut and spliced. The plates can be put on in situ after the two halves are raised.

:) Taking it easy is the important bit. People get hurt when you don't think about it FIRST. :)

The oak truss can go up in bits, and be assembled up there, as I intend to make it myself, I should be familiar with how it fits together. Its not going anywhere neer so high up, or in such an awkward place to get to.

That's how I've seen the RSJs done. Bolted together in sections
