– and its ingenious Allround technology
It’s the Allround Connector
that gives you the edge:
design, top-quality material
and precision manufacture
by Layher guarantee
stability, quality and safety.
The »Original« Layher AllroundScaffolding®For demanding and complex scaffol-
ding applications – i. e. wherever
conventional scaffolding technology
falls short of optimal thus cost effec-
tive use, Layher Allround Scaffol-
ding® convincingly comes in with an
unmatched range of advantages:
unbeatably fast assembly, persua-
sive economic arguments and an
extensive range of series-produced
accessories. This and more is avail-
able thanks to allround versatility
from one system.
Connections in this quick to assemble
and spannerless scaffolding system
make a unique combination: providing
structural strength immediately on
assembly and subsequent ultimate
force transmission while offering a
choice of automatically right-angled
or splayed connections with unrival-
led safety right from the start.
Layher Allround Scaffolding® has
become a by-word on the market for
both modular scaffolding and out-
standing quality.
Layher Allround Scaffolding® is an
investment in a perfected and com-
plete system – in steel or aluminium
– with all the necessary approvals,
and rapid, safe, highly versatile and
continually profitable scaffolding
construction.

More possibi l i t ies. Unique connection technology.
The Allround Force Connector makes it poss
. . . the component is
immediately secured against any possibility of shifting or dropping out. That means:
safe 1-man-assembly,
whatever the height.
Structural assembly from thebeginning: By sliding the wedge
head over the rosette and
inserting the wedge into
one of the holes…
A blow with a hammer on the wedge transforms the connection from structural assembly to force transmitting rigidity.
For industry, chemical plants, power
stations, aircraft hangars, shipyards,
theatres and arenas, at any site or
facility, the “Original” does full justice to
its reputation as an all-rounder.
As work and protective scaffolding at the
facade, as birdcage, tower and suspended
scaffolding, or as a rolling tower – the
right scaffolding at all times and for all
jobs and requirements.
For very difficult ground plans and
anchoring conditions, for very irregular
structures, and for jobs with increased
safety requirements.
The flat rosette without
recesses or raised edges
prevents clogging with con-
crete, sprayed foam, dirt etc.
that might otherwise hamper
assembly.

What use is a spannerless con-
nection if the time saving
is lost by having to measure
for right angles?
Built-in assembly speed: the four
narrow holes in the perforated
rosettes centre the ledgers auto-
matically and securely at right
angles – while the four large
holes permit the alignment of
ledgers and diagonal braces at
the required angle.
Forget about ... ... lengthy measuring and levelling,... time-consuming spanner work,... repeated adjustments,... tube/coupling entanglements,... undefined structural
force situations...
The wedge head is precisely
matched to the radius of the
standard at the front end –
so forces are applied to
a surface not a line and always
centrally into the standard.
The result of superior design: up to 8 connections at various angles can be made in one plane with the structurally ideal Allround Connector. The assembly of the system is straight-forward.

Z-8.22-64: The Allround Modular System in steel (new version K 2000+ and previous version [Variant II])
Using the latest computer technology,
the Layher Allround connector, which has
been proving its worth since 1974, has
been optimised: The outcome is the new
K 2000+ connector.
Its outstanding benefits are…
� substantially higher loading capacities� bending moment of ledger connection: + 49%
� vertical diagonal braces: +113%
That means: Material savings.New possibilities.
� Compatibility with Allround material
of the previous design is assured
as a general principle.
When K 2000+ diagonal braces
are used with previous Allround standards,
higher loading capacities are approved
for these connections,
see approval.
That means: existing material is »upgraded«.
The Allround Connector that gives you
the edge: design, top-quality material
and precision manufacture by Layher
guarantee stability, quality and safety.
Layher Allround scaffolding has – in addition
to its German approval – other national
approvals in all the European countries.

Approval for standard assembly.
Z-8.22-64
� Approval for standard assembly as facade scaffolding:
Besides the approval for the Connector,
Allround Scaffolding® is also approvedfor assembly as facade scaffolding,meaning that assembly is possible with-
out additional calculation.
Vertical diagonal braces are not required
in the standard assembly.
� For facades too, Allround Scaffolding® offers the well-tried Allround benefits:
� low susceptibility to clogging
� »automatic« right-angled structure
� versatility
� high loading capacity
� decks can be fitted or removed at any
point and at any time
� Allround Scaffolding® is an intelligent and economical solution.
Particularly irregular facades and structures
with curving ground plans can be enclosed
economically and safely using Allround®
scaffolding.
This is where Allround® scaffolding with
its superlative adaptability offers an intel-
ligent and economical alternative.

Allround Scaffolding in aluminium
Z-8.22-64.1
Possible applications in which the speci-
fic advantages of the Layher Allround®
scaffolding systems made of aluminium
can be used to particular advantage in
terms of both profitability and design ele-
gance include
� rolling towers
� suspended scaffolding
� scenery in theatres
� for trade fairs and events
� a support base insufficient to with-
stand the forces from a steel scaffold-
ing structure
� historic natural masonry requires refur-
bishing, but is crumbling under the
effects of the environment and hence
is unable to bear the weight of steel
scaffolding.
�These are possible scenarios where
the use of Layher’s Allround aluminium
system is ideal.
Other outstanding arguments in favour of
using Layher’s Allround in its aluminium
version are:
� faster assembly
� low loading weight
� less physical strain on the assembly
personnel.
Layher Allround in aluminium can be
used in conjunction with Layher Allround
in steel, as both systems are compatible.
