Quality Factors & Designation
Quality Factors
All of Doka Ringlock products are engineered to meet
the highest quality standards based on three simple
factors:
▪
Material
We only use the highest quality steel in our products.
Our steel is certified and tested, it conforms to or
exceeds industry standards no matter the location or
climate.
▪
Fit
Doka products are engineered with versatility and
usability in mind. Our modified product designs
increase efficiencies and productivity, saving your
projects time and money.
▪
Finish
Where applicable, our products are finished and pro-
tected by hot-dipped zinc galvanizing. This method
of finishing maximizes the utilization and extends the
product life.
For additional information on Ringlock system compo-
nents please consult your local Doka representative.
Designation
The Designation of Ringlock in accordance with
EN
12810-1:2003
is:
Scaffold EN
12810 - 3D - SW06/307 - H2 - B - LS
Service Load Class 3 may be extended from Service
Load Class 1 to Service Load Class 6 if required
although there are restriction on bay length for Service
Load Classes 5 and 6. This User Information only con-
siders Service Load Class 1 to Class 3 as the general
loading required of a system scaffold under normal cir-
cumstances.
Service Load Class 3: The following combinations of
platform width and bay length are also available:
SW06/73 to SW06/307
CLADDING:
Maximum permissible heights and tie pat-
terns are given for both unsheeted, debris netted and
sheeted scaffolds.

Node capacities 1.65 Safety Factor
The Ringlock modular scaffold system may be used as
a work and protective scaffold according to EN
12811
with load class 3. The system dimensions of the stand-
ard design are bay length L
≤
3.072m and bay width b
= 0.732m. The maximum height of the top scaffold layer
is 24m plus the spindle extension. If the actions on the
framework from the traffic load do not exceed the ser-
vice value of the loads specified in EN
12811,

3,
the standard design can be used without further verifi-
cation. According to EN
12810, the following designa-
tion must be used for the standard designation of the
Ringlock scaffold system as a facade scaffold:

All the decks of the Ringlock modular scaffold system
can be used as overhead protection. The following
information provides an overview of the most important

and is taken from the general building approval / gen-
eral type approval Z-8.22-992.
