Quantity Schedule
850 width towers
Number of working platforms allowed
The MAXIMUM SAFE WORKING LOAD (the combined weight of the
users, tools and materials) that may be placed on the tower is the
total weight less the self-weight of the tower. The total weight for the
towers shown in the schedule is 950kg.
Example 1:
An 850 tower built using the 3T method with a 4.2m platform height
and a platform length of 1.8m has a self-weight of 151kg.
950kg total weight - 151kg self weight = 799kg maximum safe
working load (users, tools and materials).
Example 2:
An 850 tower built using the 3T method with a 11.7m platform height
and a platform length of 2.5m has a self-weight of 408kg.
950kg total weight - 408kg self-weight = 542kg maximum safe
working load (users, tools and materials).
For greater heights and loads, consult your supplier for guidance.
Platform loading
On an 850, tower a platform comprises of a single deck only. The
maximum safe working load (the combined weight of the users,
tools and materials) that may be placed on a platform is 275kg,
evenly distributed over the deck.
The quantities on pages 11 and 12, will enable BoSS towers to
be built safely and therefore comply with the requirements of the
Work at Height Regulations 2005. They include double guardrails
to all platforms, and toe boards will need to be added if any levels
are used as working platforms and for storage of materials.
EN 1004 requires platforms at least every 4.2m, and these
measures will exceed that requirement.
