Abseiling Window Cleaning
You are all aware to what window cleaning is, a person employed (or yourself) to clean a window with use of liquids, specialist cleaning fluids. Normal window cleaning would not in general require the cleaner to go above two stories in height to clean windows. Their usual method of reaching high places is the use of a ladder. Another way is Abseiling Window Cleaning.
This is where abseil window cleaning differs, it requires the cleaner to go up great heights (the tallest of buildings) sometimes even skyscrapers to clean windows. They reach the high places by using access equipment. Access equipment like cherry pickers are used for heights that are not so great.
However it also requires the cleaner to go to the very top of the building, from here a harness is attached to the cleaner. This harness is secured to the roof of the building to prevent the cleaner from falling should he loose balance or grip. The window cleaner is then lowered down the side of the building. A bucket is lowered with him on a separate harness, and he begins the process of cleaning windows. This does sound like a very dangerous process but the company must comply with strict safety rules and regulations. Multiple safety checks will be done to the harness by professional people.
There is a slightly safer method. Abseil window cleaners use a platform that is lowered down the side of the buildings which their buckets and cleaning products are placed upon. The platform is big enough for multiple cleaners to be lowered down on and freely walk around to cover all the windows on the side of the building. The cleaners are still harnessed to the roof of the building for extra safety, should the unthinkable happen to the platform.
