The article  introduces the suspended platform (swing stage) application on the high rise building facades cleaning, and its advantages than BMU and Bosun’s chair.

  •  The main equipments that are used in exterior wall cleaning include three kinds as below:

1.Building Maintenance Unit, also is called BMU

high rise building maintenance
2.Suspended Platform
suspended platform

3.Bosun’s Chair

The BMU is a special equipment for exterior wall cleaning of high-rise building. Its main usage is cleaning exterior wall of modern high-rise building, which change the traditional suspended work operation into automatic, efficient, high quality mechanical operation. It is the latest generation of powerful exterior wall cleaning robot, and fills up the blank from domestic to overseas in high-rise building exterior wall maintenance. In China, some of senior high-grade constructions, which were built in 80-1990s, were designed by foreign architects and they had considered the installation of BMU since then and adopted abroad BMU to maintenance building. These efforts have laid a good foundation for building cleaning. But since 1990s, there are many buildings had not considered the application of BMU when they were designed and some of them can not be installed BMU, at the same time, BMU does not belong to standard products and also often bring higher cost, all of those lead to BMU has not been widely used nowadays.

Because of Bosun’s Chair’s flexibility, it has been widely adopted in the world. However, as its risk in operation and often brings accidents, the Bosun’s Chair has been more and more replaced by suspended work platform. We believe this is a tendency of development. Now, in China, many cities have already stipulated that in aerial work cleaning, workers must use suspended work platform and forbid to use Bosun’s Chair , to avoid more accidents happening.

The suspended work platform is a new type of aloft working machinery. Because of it’s operate smoothly, comfort, safety, energy saving etc, it has been widely used in domestic decoration and cleaning industry.

  • Use suspended platform on high rise building cleaning

Preparation work before construction
1. Check the work site and assure the plan.
Check the roof condition and ensure that it can be installed suspended platform and sure the movement has no obstacle like neon lights and billboard. The engineers design construction plan.

2.  To ensure the construction environment without wind, snow and high temperature, low temperature phenomenon. The wind in site should less than 6 levels.

3.  Prepare cleaning tools such as bucket, gun, towels and sucker etc.

4.  Two workers carry cleaning tools, get into platform cradle and fasten safety belts.

Do safety inspection before operation.

Operation process

1. Use water gun to wash corners and remove dust.

2. Dip spreader into barrels and after it fully absorb sanitizer, we smear evenly on the surface of glass. Later use wiper

scrape glass up and down including window frame and corners. Ensure to pull crossly and no miss some small place and then use towel dry it.

3. After finishing one position, let the platform move to the below site and when end the cleaning from top to bottom, we turn left or right to adjacent position and continue to work from top to bottom again.

4. After finishing total work, sorting machines and tools and remove fences and billboard and clean the water on ground.

5. Cleaning and maintenance equipments and after removing dust and dirt we pack the device in warehouse.
