Building Maintenance Units - BMU

Mounted permanently at roof level, a BMU is the most complete form of suspended access system, providing full lateral, horizontal and vertical movement of the working platform. Rostek’s BMUs provide hoisting heights of up to 400 m and jib outreach up to 35 m, enabling safe access to even the tallest and most complex building façades.

Features and benefits:

• A typical working load limit of 250 kg, additional loads can be designed into the systems to facilitate glass replacement winches for future maintenance of the building.
• Range of BMU machines that can either be fixed position or running on anchored or free-laid tracks. 
• Option of trackless machines that can travel on a concrete surface with the aid of a guide rail.
• CE approved and manufactured in accordance with European Standard EN 1808 incorporating fully counterweighted designs to ensure complete stability in all working load conditions.
• Manufactured from hot dipped galvanized steel and aluminium cladding, complete with a paint finish in a range of RAL colours.
• Ergonomically designed cradles provide a safe and comfortable work environment with widths ranging from 2.0 m to 7.2 m.

Systems:

Rostek-UK Roof Trolley BMU:

• For buildings with few projections, such as balconies or terraces, or where it is possible to position the track on the roof edge, Rostek’s Roof Trolley System is a low profile, very easy to use and a cheaper solution compared to fully counter-weighted BMU Systems.
• The Trolley unit runs on twin aluminium tracks positioned directly over the parapet (the front track is generally set back by 100 mm to ensure it is not visible from the ground).
• The typical weight of our lightweight Roof Trolley is 500 kg, making it suitable for lightweight roof and façade structures.

Rostek-UK Compact BMU Machine:

• On buildings with few projections, such as balconies or terraces, or where it is possible to position the track close to the roof edge, Rostek’s compact crane BMU will cover most requirements, with an outreach of up to 10 m.
• Each machine is completely counterbalanced and incorporates a rotating head to ensure the cradle remains parallel to the building face at all points.

Rostek-UK Complete BMU Machine:

• The complete crane machine is suitable for buildings that have larger terraces and more complex façades. Boasting an outreach of up to 35 m, they can cope with the majority of situations.
• With their base and running gear being similar to the compact machines, they can travel on twin steel tracks, or alternatively they can operate from a fixed position. 
• Depending on the specific characteristics of the building, the jib can be either fixed or telescopic.

Rostek-UK Special BMU Machine:

• For buildings with particularly challenging façade features, like large towers, parapets or screens, Rostek-UK can incorporate a variety of bespoke functions into its machines to overcome the most demanding situations.
• for buildings with high parapets, the BMU may have a telescopic or parallelogram mast to raise and lower the jib over the parapet.
• Turrets can be added into the jib ends to allow the cradle to pass over high obstacles without the need for luffing jibs, alternatively machines with articulating “knuckle” jibs can be supplied to allow the cradle to reach around the obstruction.

Rostek-UK Pantographs:

• To enable access to façades beneath projections, such as soffits or brise soleil shading, or into recesses, the machines can incorporate a special pantograph cradle unit, which enables the cradle to maintain close contact with the building façade.
