Step 4
➤
Place the Stair Treads between the Stringers. Make
sure that the pin on the Stringer fits exactly into the
slot holes of the Tread. Secure the steps with a blow
of a hammer.
➤
Install advanced Guardrails (Using Ledgers) in the
lift above. Our recommendation would be to use pro-
prietary Scaffold Steps and it is recommended that
both levels of Guardrail are installed at the same
time whilst the Scaffold Step is in place.
Step 5
➤
Complete the stair by assembling all Stair Treads
from bottom to top, Planks on the first landing,
Guardrails along the stair and on the first landing,
and Toeboards on the first landing.
➤
Use the Scaffold Step to assemble a temporary plat-
form and single advanced Guardrail such that this
can be used to erect the second landing.
➤
If necessary an opening can be left in this platform to
allow access by ladder. The opening is formed using
a Plank to Ledger Transom and a 1.09m Plank. If
necessary follow the guidance provided in 'Ladder
Access' section.
The tower is now complete up to the first lift.
