Setting trusses

[Duffster]

and purlins, and bracing, and fascia boards............all at once.

This is from a building that I built a few years ago.

Way to do it. Is the crane holding it up while the crew builds the house underneath it?

That's amazing. I never thought of that!

Is that the spot where the building was to be built or was it moving over to a framed building already in place.
Looks like a great idea, just don't know if I'd want to work under it
I don't see any foundation underneath, so probably just lifting from there.

Did you have to custom build those spreaders, or are they something the crane company provided?

That would definately be an easier, safer, faster way to build a roof system, I like it!
How does the cost of the crane compare to the ammount of labor saved?
The main thing in building the roof seperate would be making sure everything is good and square.

We used to build up gable end truss sets and then set them with a crane..

stand the gable truss along side the the first common... set all the outlookers (including any hurricane fasteners) and run the sheething up the rakes...put the siding (or plywood in case of stucco etc) and then install the soffiting and fascia...all this is much easier to do on the ground than in place from scaffolding...

lift in place with a crane and you have the first 4' of roof all done and you can use it to brace off the rest of the common trusses..

No, maybe I will try that.

The building was just behind the crane out of site.

I had the spreaders engineered and custom built for me. The are adjustable and can be used on any size building of 64' or less. Bigger buildings we did in 2 pieces.

The crane time/charge was less this way then setting trusses one at a time.

The crane time from arrival to departure was less than 2 hours.

Labor savings wasn't all that much but we were working on the ground instead of in the air of scaffolding.

Sounds like some of the same things we did.

I always prefer to work on the ground if possible.

Another factor is the safety aspect.
Our safety police would want all workers harnessed and or fences everywhere and fines are fairly hefty if caught.

thats the normal way to set long span (80-120') trusses as you can safely work them on the ground set all the required bracing and lift a group up all at once.

just one thing to say, THAT'S CHEATING.

Have to admit though, much easier than building in place.
