Roof Mounted Guidance Systems
Roof mounted building maintenance units are permanently installed on buildings and other structures to provide safe and efficient access for exterior maintenance works such as cleaning, light maintenance, and glass replacement.
The major benefits of roof mounted facade access solutions are low visual impact, and high efficiency. These roof mounted facade access solutions are, without question, the best way of maintaining building facades over 5-stories high. Each unit is supplied with a platform suspended by four cables.
A roof mounted track guidance solution can be one of three different types:
Cast in stainless steel U-bolts – The traditional option. Cento can provide the stainless steel U-bolts to be tied into the structural steelwork and cast into concrete upstands by other contractors.
Galvanised steel posts – Steel upstands fixed back to the reinforced concrete or steelwork structure. These can be through bolted or welded.
Freely laid rail (FLR) – Galvanised steel upstands, including links between the front and rear track. There are no penetrations of the roof finishes when using the FLR system, therefore it is quick and easy to install. It is designed to sit directly on top of the roof insulation and roof finishes.
In addition to the three options above, it is also possible to use a trackless BMU, which runs on a reinforced concrete runway. The BMU is guided by a small angle guiderail, or by the inside of a structural parapet when traversing.
The final design solution is dependant on the specific building envelope design and roof plant layout. Early consideration of the facade access system and building interface is strongly recommended to ensure the most cost effective and efficient solution is achieved.
