I'm certainly no expert, but I believe the yellow screens are protection screens that are used primarily for worker safety. They prevent falls (of workers and materials), and provide wind/weather protection for the trades working below the newly formed floor above. They can be hydraulic, so once initially positioned, crane time can be used elsewhere until the top-out of the building. https://www.doka.com/en/system-groups/doka-safety-systems/protection-screens/xclimb-60/index
