I have found a unique job in which I would like to install mast climbers about 105' high with platform lengths about 40' long. It is an interior scaffold that is about 160' long and 40' wide. I would like to have the 40' long platforms run the 160' length on each side. There would be about a 26' long distance to span. I would ideally like to have about a 1,000 lb load capacity at the center of the span. I am curious what equipment has been used in the past and if it worked out well. I'm just looking for ideas and I would ultimately have everything approved by an engineer. The customer suggested using aluminum stages to span, but I am not crazy about it. Let me know what you think! Thank you.
 
I think you may want to ask Alan Reade that one, he is the Engineer in the know, and prospectively your Engineer for this, give him a pm.
 
Alan Reade, look at the posts in the design section if you can't find him tru the pm list.

Hope you find the designer/design your looking for.
 
Fuk him off!!!!!

Mast climbing nobheads aggresively taking a lot of business off scaffs and sh1thouse firms doing a little crash deck at the bottom

I hope that ***** your bastardising collapses and noone gets hurt but your company goes bust

Christ the wombles throwing this ***** up dont even check fitting the bracing tubes into the building.....:mad:

The man is in NY joebag so his plans do not affect UK scaffs. Mastclimbers are used a lot in the states as well as swing stages.

To the OP contact instant upright for aluminium decks they have a great range.

Ha Nice sentiment Joe but as Spanner says he's a septic (the lbs and Ft should be a clue)

Morning Mr,
he tends to look at most of the posts almost every day :)

Morning Swingline,
Whilst I have not done one for many years, Mast climbers on scaffolds are a frequent occurrence in the UK, if not a popular occurrence with Scaffs.
You would need to consider the bottoming out load from the mast, it tends to be a very high impact load requiring some form of steel spreaders and multiple legs.

With regards your 26' span (8.2m approx) the 1000lb (4.5kN) point load at mid span on its own may not be an issue as the Bending Moment would be around 9.3kN m which most Aluminum Scaffold beams will take if erected correctly. (note if the 1000lb's is from you hoist it won't be enough load)

However if you are using said beams to form a gantry bridge you would have other loads in addition to consider. Self Weights of the beams and lacing tubes along with the decking plus of course a minimum live load of say 0.75kN/m Sq (15lb's/ft Sq)

Make an assumption for the sake of this conversation that the total of those loads comes to 1.3kN/m Sq you would then have an additional BM of around 11kNm for every m run on the beam.
Again assume your beams are in at 1.2m to support your boards = 1.2m x 11kNm =13.2kNm plus your point load BM 9.3kNm = around 20.3kN m.

Not a job to be speculating about prior to putting in you price.
I would recommend you bottom out what it is you need to achieve sketch it out and pass it to your Scaffold Engineer or at least a Structural Engineer for him to consider the actual conditions faced.

Regards
Alan

joebag you dived in like a salmon there eh?pretty embaressing.
 
In the UK dance floors would need to be designed to 7.5kN/m2 so your target loading may be insufficient, as Alan said you best get a designer in:unsure:
 
Worked for brands and thyssenkrupp in the states, used 16ft boards supported at 8 ft centres with 9 wire tying off 4x1 toeboards all covered under osha, i worked on a hotel development in liverpool city centre were one whole 200 ft facade was lost to these winkers on the grounds it was a lot safer yet the whole job was stopped a dozen times because of faults to the climber or debrit being dropped or caught under the thing so as to not allow it to dock properly ,embarresed mate not at all just got a lot of experience with this ***** !
 
The swing stages used to be a scaffs job,i did a few horses for them to be hung from with a Scaffolder who would set up the cables etc.
Maybe if we kept it to ourselves there would be more graft for scaffs.
Scaffolders will have to diversify to the new Innovations and keep them in house.The safety nets are a new one which should be ours but poncey abseillors may well have stole.Rigged access/crash decks from bridges is the next one that may well take off which should be a scaffs job.

Alan very good info again which im sure our American Friend will take on Board;)
