Rolling scaffolding for drywall - or other suggestions?

Hello everyone,

I have walls in the upper floor up to the roof, so in the middle about 4.5m high and less towards the sides according to the roof pitch (16°).
What would you do to be able to work up there with two people?
Set up a proper scaffold?
Buy a mobile scaffold?
Rent a mobile scaffold?
Height-adjustable scaffold trestles with 2 planks?

I discovered a mobile scaffold which would be optimal in terms of working height, especially since the height can be roughly halved by a removable module.
Unfortunately, it is only rated for 150 kg load.
Two people + Fermacell board roughly come to 200 kg.

Would you maybe put a thicker board on the platform and still work there with two people, or would you be careful?

It’s about this mobile scaffold:



I would be grateful for any tips or assessments.
Maybe some of you already have experience in this regard?

Regards
Tito

My favorite for ladders and mobile scaffolds has always been Bavaria / Mauderer (somewhere in the Allgäu). Top notch, but not for penny-pinchers - although: good tools save the ambulance ;-)

I would be afraid that it will fluctuate a lot up there.
