Platforms ascend and descend on the faces of large buildings, including skyscrapers, enabling window cleaners to access every exterior window.
Temporary scaffolding provides sturdy but lightweight platforms that are rigged using rooftop anchors. The benefits of using temporary platforms include the time and cost savings associated with installing permanent scaffolding, quick and easy assembly, lightweight and easy to move. 
Permanent power platforms are useful for custom-made window cleaning, as they can be installed and outfitted with special features that are individualized to help workers access a building’s difficult areas. They can also address additional safety features beyond those required by OSHA for non-permanent platforms.
