BoSS mobile aluminium towers are light-weight scaffold towers
used throughout the building and construction industry for both
indoor and outdoor access solutions where a stable and secure
platform is required. Ideal for maintenance and installation work or
short-term access, the highly versatile towers provide a strong
working platform for a variety of heights.
This User Guide provides you with step by step instructions to
ensure your system is erected easily and safely, using the 3T
(Through The Trapdoor) method.
The law requires that personnel erecting, dismantling or altering
towers must be competent. Any person erecting a Youngman
BoSS mobile tower must have a copy of this guide. For further
information on the use of mobile access and working towers
consult the PASMA operators code of practice.
