External stairways
There are two options for external
stairways: the HAKI UTV of steel
and the HAKI UTV of aluminium.
Both options are fitted in a similar
manner.
7.
The UTV stairway is fitted in an
external bay using ERB 700/770
and LB/ERB 2500/3050 beams.
The stairway is usually built into the
scaffold proper. Alternatively, the
stair tower is erected using separate
standards.
Set out the base jacks and erect the
standards. Fit the ERB 700/770
and LB/ERB 2500/3050 beams
into the lowest group of pockets. Fit
the transom beams for the second
lift too. At other levels, the handrails
replace the ledger beams.
8.
Fit the hooks of the UTV stairway
over the tubes of the transom
beams and lock the stairs using the
locking device.
Fit the handrail at the 1.0 m level
and provide the top end with SKRD
700/770 guardrail frames. Fit
the next set of standards, transom
beams, stairs, handrail and
guardrail frames.
9.
Continue erection up to the
desired height.
At the top level, an ERB
2500/3050 beam is fitted
externally in the scaffold. An SSK
1000 guardrail post is fitted on the
beam so that an SKRD 1964/2500
guardrail frame can be fitted
between post and standard.
Alternatively, an LB 2500/3050
beam can be combined with an
SRS 1000 guardrail post.
The guardrail frame provides
fall protection at the top level of
the scaffold. At other levels, the
next stairway provides sufficient
protection.
