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
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.
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
When we speak about a traversing roof car we mean a roof car that is designed to move around the roof of a building over a customized rail track. This is made possible by its motorized undercarriage.
A fixed roof car is placed at a fixed position on the roof and has a traversing jib to span the building or a certain region of the building.
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
A pantograph cradle is balanced by a counterweight to reach uneven facades or facades with protruding elements.
A self-hoisting gondola has two XSClimber hoisting units to be suspended from roof cars, and can be used in combination with gantries or monorails.
Gantries
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.
