AG Building Maintenance Units [BMUs]
Mounted permanently at roof level, BMUs are generally the safest and most complete form of suspended access system, providing full lateral, horizontal and vertical movement of the working platform. The BMUs available from The Access Group provide hoisting heights of up to 400m and jib outreach of up to 35m, enabling safe access to even the tallest and most complex building facades.
Our cradles have a typical working load limit of 250kg, although additional loads can be designed into the system to facilitate glass replacement winches for future maintenance of the building. The Access Group offers a range of BMUs that can either be fixed position or running on anchored or freelaid tracks. Alternatively, we provide trackless BMUs that can run on a concrete surface with the aid of a guide rail, enabling the terrace area to be utilised for pedestrian access or other activities.
All of our BMUs are CE Approved and are manufactured in accordance with European standard: EN1808 and the machinery directives incorporating fully counterweighed designs to ensure complete stability in all working load conditions.
Our ergonomically designed cradles provide a safe and comfortable working environment with lengths ranging from 2m to 7.2m.
AG Compact Crane BMU
On buildings with few projections, such as balconies or terraces, or where it is possible to position the track close to the roof edge, the AG Compact Crane BMU, with an outreach of 15m, will cover almost all requirements. Each machine is completely counterbalanced and incorporates a rotating head to ensure the cradle remains parallel to the building face at all points.
AG Complete Crane BMU
The Complete Crane BMU is suitable for buildings that have larger terraces and more complex facades. Boasting an outreach of up to 35m it can cope with the majority of situations. It is similar to the AG Compact Crane and can travel on twin tracks or operate from a fixed position. Depending on the buildings specific characteristics, the jib can be either fixed or telescopic.
AG Special BMUs
For buildings with particularly challenging façade features, for example, large towers, parapets and screens, a variety of bespoke functions can be incorporated into the BMU to overcome the most demanding situations. Turrets can be added into the jib ends to allow the cradle to pass over high obstacles without the need for lufting or BMUs with articulating “knuckle” jibs can be supplied to allow the machine to reach around the obstruction.
AG Pantographs
To enable access to a façade beneath projections, such as a soffit or brise soleil shading, or into recesses, our BMUs can incorporate a special pantograph unit, which enables the cradle to maintain close contact with the building façade.
