Intr ducti n
Intended use
Pr duct descripti n
These Instructions for Assembly and
Dismantling are supplementary to the
P RI UP Flex Staircase 100 and 125
with Deck UDG Assembly Instructions
for Standard Configuration. All notes
and data contained therein remain valid.
They describe the configuration for stair
towers 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.

Presentati nal reference
The illustrations indicate the sequences for
one bay size option. They are valid for both
1.00m. and 1.25m. bay options.
Components highlighted in red indicate
temporary installed components removed
before completion of the tower.

Pers nal Pr tecti n
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 anch ring
All anchor connections to the supporting
structure should be tested in
accordance with NASC TG4:17
Anchoring Systems for Scaffolding.
PERI UP Flex Staircase 100 and 125 with Deck UDG
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 L ad distributing base area
recting the scaffold must follow the
sequence described below!
Settlement must be av ided! The
scaff ld must nly be erected n
suitable distributi n plates n gr und
r structure capable f withstanding
all imp sed l ads!
Lay the Ledgers UH 250 (3a), Ledgers UH
200 (3b) and Ledgers UH 100 (3c) 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 250 (3a), Ledgers
UH 200 (3b) & Ledgers UH 100 (3c).

A1.3 Changes in base level
Steps, slopes and changes in level can be
accommodated using adjustment of the
Adjustable Base Plates / Base Spindles.
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.

A1.4 Base Standard UVB
Place Base Standards UVB 24 (2) over the
Adjustable Base Plates UJB (1) and
position at the required distance from the
wall. nsure all UVB Ø11 holes are aligned
in same direction.

A1.5 Ledger UH & Base Decks
Form a base frame by connecting the Base
Standard UVB 24 (2) with the Ledger UH
250 (3a), Ledger UH 200 (3b) and the
Ledger UH 100 (3c).
Two red Ledgers UH 250 (3a) are
Temporary, they will be removed later.
nsure all Ledgers UH are level by
adjusting the Adjustable Base Plates (1).
Place Steel Decks UDG 200 (9b) on the
Ledgers UH 100 (3c) as an assembly aid
to check squareness.
Four red Decks UDG 25x200 (9b) are
Temporary, they will be removed later.
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.

A2.5 Stairs Steps
Place first stair step UAR (7) with the riser
on the deck.
Move step forward to the pins on the
stringer. Rotate stair step towards the
stringer.
Position the second step (7) with the front
side on the first step. Push the step
forwards into the support of the Stair
Stringers UA (6). The upturned edges
engage in the slits. (Fig. A2.7b)
Turn the step upwards. The slits support
the upturned edges and connect both
steps. The top of the step rests against the
Stair Stringers UA. (Fig. A2.7c)
Repeat procedure up to the last step.
Lift the last step (7) slightly out of the
holder. Horizontally position nd Step UA
(8) on the last step (7). (Fig. A2.7d)
The upturned edges engage in the slits.
The nd Step UA (8) and the last step
are wedged together.
Pull back the nd Step UA (8) together
with the last step, and then swivel up. nd
Step UA (8) engages on the Ledger. Last
step engages in the Stair Stringers UA (6).
Last stair step is secured by tightening of
the bolts on the stringer (8).
Attach UBK 250/200 (10) as intermediate
guardrails and remove temporary Ledger
UH 100 (3c) above stairs.

A5 Anchoring
15
Anch rs are n t designed t carry
vertical l ads!
- Anchors should be installed
progressively along with the erection of
the scaffolding.
- Fix with suitable fixings in accordance
with NASC TG4:17.
- The load-bearing capacity of the
connecting components between the
Wall Ties and anchoring base must be
verified by the contractor.
- Install the first row of anchors at a
height of 8.0 m. The position of the
other anchors is given in P RI UP Flex
Staircase 100 and 125 with Deck UDG
Assembly Instructions for Standard
Configuration.
- Install anchors only in the levels which
have been braced with Horizontal
Braces..
A5.1Triangulated anch rs
For shorter wall spacing, both corner
standards must be connected with
triangular anchors at 45°.
Fix the Standard Couplers (16) to the
Corner Standards with Wall Ties UWT 45
or scaffold tube (15). (Fig.A5-1a)
Fix Wall Ties or scaffold tubes to the wall.

For large wall spacing up to max. 200 cm,
single Wall Ties and crossed diagonals are
to be used.
Fix Wall Ties, UWT 140 or scaffold tube

Standard Couplers (16).
Fix Wall Ties UWT 140 or scaffold tube to
the wall
Fix Scaffold Tubes (18) to the Wall Ties
UWT 140 or scaffold tube using Swivel
Couplings (17). (Fig. A5-3a and Fig. A5-4)
At the intersection point of the diagonal
Scaffold Tubes, use Swivel Couplers to
