Getting an RSJ into Place
 

I need to get a 7m 254*102*25 RSJ ridge purlin into place, this is
gonna weigh in at at least 350kg, so me and the girlfriend wont be
able to lift it onto the roof.

The "normal" way I guess is with a crane, but I can't get a crane to
the house, nor can I get a big enough teleporter or excavator in.

There is a window below the RSJ at both ends, the tops of the windows
are not build yet.

The current plan is to get the thing in through the window (we can
drag it with the bobcat), then using scaffolding and pullies lift it
up, building the scaffold underneeth to stop it dropping. When we get
to the top of the windows we can put the bricks in under it.
My worry with this plan is that the scaffold will have to hold if for
some days while all the brickwork sets, and a big storm may not be
good for the situation.

Is this the way is normally done, or is there some trick that I have
not thought of yet ?

Thanks
Rick

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 ?

350kg is not that much of a load from a scaffolding point of view (i.e.
same as 3 hefty blokes working on one scaffold) as long as it is well
constructed, and you can spread the load over a few poles etc.

(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.

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

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
