Rotrex OnSite can maintain, inspect and test most types of Building Maintenance Units.
All systems should comply with BS6037 & EN1808 and should be maintained in accordance with these regulations and manufacturers’ recommendations.
Working with building owners and building managers, Rotrex OnSite ensures that building maintenance units (BMU's) remains in top condition, ready and safe to use.
BMU's can be manual, semi-powered or fully powered and are generally installed onto a tracked runway system, that is in turn fixed back to the roof structure. Depending on the design of the BMU either a dedicated cradle or a separate cradle set can be suspended from the jib. Other types of BMU include trackless, pedestal mounted and freely laid track.
Tracked systems – The BMU is fixed to a twin runway track that generally follows the perimeter of a building allowing full coverage of the façade. Older versions of tracked systems comprise of a single rear track with a concrete or steel bearing surface for the front wheel to bear upon.
Trackless systems – Trackless systems run directly on specially constructed roof surfaces and are fully counterweighted to prevent any uplift or overturning. There is generally a guide around the extents of the roof area in which it is to be operated.
Pedestal mounted systems – A pedestal mounted system is fixed directly to the roof structure and pivots through 360 degrees. This type of system is generally designed with either a telescopic or folding jib, which allows access to all extents of the building.
Freely laid track system – This system is a mixture of a tracked system and a trackless system. The BMU is fixed to a twin runway track that is fixed to pedestals, which are in turn positioned on top of the roof finishes. The BMU is fully counterweighted to prevent any uplift or overturning.If you require BMU support - contact us
