Load Cases (Permanent) There are six load cases for consideration for Permanent BMU’s suspending platforms, as follows. Worked examples are given in Appendix A1. These load cases apply when determining the strength of the BMU design only. Load Case 3 does not transfer the reaction loads onto the structure.

Design, manufacturer and install one new exterior long boom BMU whose characteristics meet the requirements of this specification. Operational Procedures and Maintenance Manuals. Installation of fixtures embedded into concrete. Light-duty anchors to secure electrical cords. A. Product Data: All submittal information shall be in English.

Weatherproof sockets on the building (socket type to match with plug on BMU.) Provide 1 No. 1-Phase, Neutral, Earth – 3 pin AC power supply for use of maintenance tools.

A building maintenance unit or BMU is an automatic or remote-controlled mechanical device, usually suspended from the roof. It moves systematically over some structural surfaces while …

For structural engineers using the limit state method as per Eurocodes EC1 and EC3, it is recommended that the following factors be applied by the as a minimum to the load cases for the purpose of identifying the design loads for the superstructure (building).

The document provides calculations for the building maintenance unit (BMU) support structure on a building roof. It includes: 1) Calculations for the H-beam track that supports the BMU, checking for bending moment and deflection.

A Building Maintenance Unit – BMU – is a mechanical and electronic crane suspended from the roof, which moves systematically over a structure while carrying human window washers or any other specialist for the maintenance of the facade.

This document discusses building maintenance units (BMUs) used for cleaning and maintaining the exteriors of tall buildings. It covers four sessions on BMU introduction, design principles, safety features and regulatory requirements, and temporary gondola design.

Permanent Access Equipment: All types of BMU’S, travelling and fixed ladder and Gantry Systems together with their tracks, monorails, cradles, davits and suspension gear. Permanent Rope Access Anchorages: Monorails, davits, or individual anchor points used to support rope access equipment.

Often referred to as a window cleaning cradle, a gondola or a gantry, Building Maintenance Units (BMU) are a type of permanent mechanical access equipment generally installed on the building’s roof level that is operated manually, automatically or by remote control.
