Mobile Towers - 3T method
Introduction

Preparation and Inspection
Please read this User guide carefully. Please note that diagrams are for illustrative purposes only.
User guides are also available to download - please contact us for details.
BoSS mobile GRP (breglass) towers are light-weight scaold towers for use in Zone 1 applications
where aluminium or steel systems are either unsafe or unsuitable. They provide indoor and out-
door 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 towers must be competent. Any person erecting,
dismantling or altering a BoSS Zone 1 mobile tower must have a copy of this guide. For further in-
formation on the use of mobile access and working towers consult the PASMA code of practice. If
you need further information, design advice, additional guides or any other help with this product,
please contact Altrad Generation.
The BoSS Clima aluminium system has been tested and certied to EN 1004: 2004 Class 3
Inspect the equipment before use to ensure that it is not damaged and that it functions properly.
Damaged or incorrect components should not be used.

Safe Use
Lifting of Equipment
Stabilisers/Ballast
• Check that all components are on site, undamaged and that they are functioning correctly -
(refer to Checklist and Quantity Schedules). Damaged or incorrect components should not be
used.
• Check if the ground on which the mobile access tower is to be erected and moved is capable of
supporting the tower.
• The safe working load is 275 kgs (606lbs) per platform level, uniformly distributed up to a
maximum of 950kgs (2100lbs), per tower (including self weight).
• Towers must always be climbed from the inside using the built-in ladder during assembly and
use.
• It is recommended that towers should be tied to a solid structure when left unattended.
• Adjustable legs should only be used for levelling.
• Tower components should be lifted using a reliable lifting material (e.g. strong rope), employing
a reliable knot (e.g. clove hitch), to ensure safe fastening and always lift within the footprint of
the tower.
• Assembled mobile towers
• Stabilisers or outriggers and ballast weights should always be tted when specied.
• The Quantity Schedules show the recommended stabilisation. In circumstances where there is
restricted ground clearance for stabilisers/outriggers, contact your supplier for advice. Ballast
must be made up of solid materials (i.e. not water or loose sand) and should not be positioned
to overload individual legs. Ballast should be secured against accidental removal where
practicable, and be supported on the lowest rung of the bottom frame.
