Introduction
Intended use
Product description
These Instructions for Assembly and
Dismantling are supplementary to the
P RI UP Flex Stairs 75 Instructions for
Assembly and Use – Standard
Configuration. All notes and data
contained therein remain valid.
They describe the configuration for stair
towers with the staircase units in the
same direction and stair towers with
alternating staircase units as a means
of access for temporary work to be
carried out on working areas situated
above ground level.
The assembly and dismantling
sequences describe a short-lift system
of work in compliance with NASC
SG4:15 Preventing Falls in Scaffolding
Operations.
3
Presentational reference
The illustrations indicate the sequences for
one bay size option. They are valid for both
2.5m and 3.0m bay options.
Components highlighted in red indicate
temporary installed components removed
before completion of the tower.

Safet considerations
4
Personal Protection
nsure persons are clipped to suitable
anchor point before moving on and off
temporary platforms.
For the scaffolds in this manual, safe
connection points are:
Any Rosette within a completed
scaffold lift.
Any Rosette up to 1m above a top
platform level.
Any Ledger connected between two
uprights within a completed scaffold
lift.
Any Ledger connected between two
uprights up to 1m above a top
platform level.
Inspecting the anchoring
All anchor connections to the supporting
structure should be tested in
accordance with NASC TG4:17
Anchoring Systems for Scaffolding.
PERI UP Flex Stairs 75
Instructions for Assembly and Dismantling – Short lift system to SG4:15

Always begin erecting at the highest
point, preferably at an internal corner.
A1.1 Load distributing base area
recting the scaffold must follow the
sequence described below!
Settlement must be avoided! The
scaffold must onl be erected on
suitable distribution plates on ground
or structure capable of withstanding
all imposed loads!
Lay the Ledgers UH 300 (3) and Ledgers
UH 150 (4) down to determine the length of
the surface to be scaffolded. This will fix
the distance between the Adjustable Base
Plates UJB (1)
A1.2 Adjustable Base Plates UJB
Position Adjustable Base Plates (1) at the
ends of the Ledgers UH 300 Plus (3) &
Ledgers UH 150 (4).
A1.3 Changes in base level
Steps, slopes and changes in level can be
accommodated using adjustment of the
Adjustable Base Plates / Base Spindles.
UJB 38-80/55
Yellow handle
Base Spindles TR 38-70/50, without
coloured handles, may be used instead of
Adjustable Base Plates UJB (1). xtension
range = 47mm – 535mm to top of collar
handle.
Adjustable Base Plates UJB 38-50/30 with
red handles have a maximum extension of
355mm to top of collar handle. Adjustable
Base Plates UJB 38-80/55 with yellow
handles have a maximum extension of 595
mm. to top of collar handle. Check with
P RI for suitability of use.

A1.5 Ledger UH
Form a base frame by connecting the Base
Standard UVB 24 (2) longitudinally with the
Ledger UH 300 (3) and transversely with
the Ledger UH 150 (4).
nsure all Ledgers UH are level by
adjusting the Adjustable Base Plates (1).
Place Steel Decks UDG (9) on the Ledgers
UH 150 (3) as an assembly aid to check
squareness.
Do not secure Ledger wedges at this stage
The decks used at the base are an aid to
erection only, they may be removed later.
