Does anybody know how many stair treads in a row you can fit before you need to provide a platform?

I assume its the max lift height.....just like any permenant staircase.
I have a great way of doing stairs without treads and thousands of transoms ;)

Isnt it something like 5m as the Maximum length of a ladder, before a rest area/platform needs to be added?

Wouldn't Staircases be the same?
5m, then a break, then another 5m and so on?


I usually do 1 lift, then a return and another lift, like Ians diagram.

Thanks Gents

But i'm talking of a staircase external to a scaffold at 90 degrees to it, rising upto a platform around 4m high.

The ladder rest point is 9m, you should always get a design for staircases....I do :/ honest...

We normally put 9 treads in a 2m lift then a platform the same as Ian's

16 Risers which is 15 treads, two straight flights before a 90deg change in direction is a requirement.

6m run is the max. Portacabins stacked have pre fab steps, max riser 9 inch.

Collo, 16 in one run
it also depends upon who's using it, and as what

after doing a few in a row i find it easier just having doing everything at 45d what ever you lifts are going to be bolt to bolt make the distance between center to center of the tranny. ledger of stair case the same, and if possable make themw alk up 1 light then across scaff and then up again less stairs to place in and at 45d center to center of doubble i make 310mm but on the lift hight i mesure form bottom ledger to top ledger on stair case and / by 310 give you the anount of stair treads if this all make sence to you lol

To get ure perfect stringers,whatever the height is down that's what it is out and back up,45 degrees

The flat pack stair cases we use range from 2m - 6m
depending what access is required, you are usually better using the smaller ones if access is to each boarded lift (assuming every lift is boarded)
