Question:
Is it a malacha on Shabat to use a folding ladder similar to opening an umbrella?
Answer:
Hello,
Opening a ladder, as long as it isn't a roofers ladder is permitted. It is similar to opening a folding chair, which is build in a way to open and close all the time, therefore it isn't bohen or fixing it. The issue with opening an umbrella is because the umbrella fashion a temporary roof.
Best wishes
