The content below is aimed at clarifying Youngman Group’s position on the question of mixing tower components from different manufacturers.
This is a practice that Youngman Group strongly advises against because of the potential safety risks for users, and their inability to rely upon the manufacturers Product Liability Insurance in the event of an accident occurring as a result of mixing components from different manufacturers.
Working at Height involves managing risk. In the UK, as in many other Countries, we have extensive regulations and standards governing the selection and use of access equipment for Work at Height. In Europe, the standard for Mobile Access Towers is EN 1004: 2004, and the principal legislation governing use is the Work at Height Regulations 2005 (as amended). Selecting high quality equipment which meets the relevant standards and ensuring operatives are competent and appropriately trained is fundamental to user safety.
Youngman Group Limited designs and manufactures its BoSS tower system in accordance with European Norm EN 1004: 2004. The BoSS Tower System has been tested and approved to EN 1004: 2004 and carries both the British Standards Institute Kite mark and the GS mark from TuV Nord.
Securing the BS Kite mark and TuV’s GS Mark requires compliance with every clause in the Norm; the submission and approval of detailed structural calculations for every tower configuration we supply; production and approval of a detailed User Guide for every tower configuration; physical testing of our tower system and, to maintain these approvals necessitates regular audits and inspections by the British Standards Institute and TuV.
These approvals are for towers constructed solely from approved BoSS components manufactured by Youngman, and are your, and your customers, guarantee that the BoSS system and its components meet the European Norm and that, when properly maintained, and used in accordance with the BoSS User Guide, and provide a safe system of access.
In the event that components from another manufacturer are mixed with BoSS components to form a tower then the above approvals are invalid. Similarly, if another manufacturer has EN approval for their system, this too will be invalidated if components are mixed.
Whilst the dimensions of components from other manufacturers may be similar to BoSS, the materials used and the manufacturing processes mean the strength and performance of such components can be very different. Youngman Group, in common with other leading manufacturers, does not share their strength and performance data with third
In practice this means a separate set of calculations for both strength and stability needs to be carried out for every different permutation of component mix, in every conceivable tower structure, built from mixed source components. This is impracticable, and is why manufacturers such as Youngman cannot accept liability for the consequences of accidents resulting from the mixing of BoSS components with those from other manufacturers.
