Building Maintenance Units

Facade cleaning on mid- and highrise buildings start with Building Maintenance Units. Building Maintenance Units are permanent solutions and with the right maintenance can stay on buildings for decades.

BMU's for facade cleaning

Mid- and high-rise buildings need scheduled maintenance to keep them in pristine condition. Most of the facades of these buildings are maintained by Building Maintenance Units (BMU’s). These BMU’s give workers easy and safe access to the facade of a building, and are therefore called facade access solutions/equipment.

Our facade access equipment is designed to reach every part of a building’s facade and at the same time, provide maximum safety to the ones operating and working inside the cradle of the Building Maintenance Unit.

The challenges we encounter

  • The Geometry of the building: Every building could require a different solution for facade access and window washing. We provide solutions for all type of buildings or skyscrapers.
  • Fully customized: Our BMU’s are designed at a drawing board and become a reality in our assembly hall, fully customized to the building’s needs, and capable of reaching any spot on the facade.

  • Advanced technology: We have built the most complex and advanced BMU’s in the world, including functionalities as remote maintenance, camera monitoring and wireless radio frequency control.

  • Minimum visual impact: We create our BMU’s with minimum visual impact, always respecting the aesthetics of a building.

  • World class service: Our service professionals are well-known for superior customer service. Therefore we have unique knowledge and access to the history of our machines from design and installation stages.

Facade window cleaning / inspection

BMU’s are often used for window cleaning, inspection, light maintenance and caulking, especially when concerning high-rise buildings. Depending on the facade of a building (straight or uneven) we offer different BMU solutions.

Facades with protruding or uneven elements can have challenging spots which are hard to reach. That’s why we create customized BMU’s that give maximum safety to the window washers or maintenance workers and at the same time make sure every area of a building can be covered. Please see different façade access types in this section.

Glass replacement unit (heavy maintenance)

Besides window cleaning, our BMU’s can be equipped with a Glass Replacement Unit and therefore have the ability to replace broken or damaged glass panels or windows. Remove the existing panels with the BMU and pick up a new glass panel from the ground – or a lower level. Read more about glass replacement units for different facade types in this section.

Our solution types

Designed to facilitate work on the inside of buildings.

Roof cars

Roof cars are used to position workers (for example window washers) in the cradle in front of the building. Roof cars are customized for different situations and can also be incorporated inside a building in order to minimize the visual impact.

Our roof cars can be an combination of all of the below

Fixed base, traversing base, fixed jib, telescopic jib, luffing jib, articulated jib (knuckle) telescopic column, scissor base column, mounted on the roof floor, mounted on the parapets external (crown) and internal, climbing BMUs

Cradle types

We offer different types of cradles, starting from a standard cradle width of 8 feet.

Cradle widths can be customized for narrow spaces and large surfaces of the facade. Besides a standard cradle, we distinguish these different types of cradles:

  • Standard cradle,
  • double access cradle (knuckles BMU)
  • Pantograph or telescopic cradles
  • Self-hoisting cradles


Gantries are also known as traversing work bridges, gantries are the perfect solution for both the external as internal cleaning of glass atriums that usually are difficult to access.

Monorail systems

Our monorail systems are suitable for both indoor and outdoor use. Monorails are ideal for medium-rise buildings with complicated designs and hard-to-reach areas.

A monorail system basically consists of three parts: the rails, manual or motorized trolleys which traverse a self-hoisting gondola or platform over the rails. Conveniently, a monorail system can be fixed to a building’s parapet or ceiling, which makes this system able to tackle even the most complex routes.
