How Do People Clean Skyscraper Windows?

Here are four of the most common skyscraper cleaning mechanisms:

Boom – One of the most popular cleaning systems historically, the boom lets a building’s facade be accessed easily by a large team. The boom system is permanent and can be operated on-gantry or off.

Carriage – These rail-mounted carriages enable gantries to cover larger areas of a building’s facade due to their ability to move left and right. As with booms, they are permanent structures and cannot be moved around the building.

Portable davit – The cheapest and simplest solution for cleaning skyscraper windows, portable davits move between fixed bases on a roof, enabling access to different sides of the edifice with just one davit-based system.

Bosun’s chair – A more modern development in skyscraper window cleaning technology, the bosun’s chair gives a single cleaner access to a tall building’s windows from a safe seated position. They are ideal for tight areas and use over long periods.
