shown.
In all cases, users are obliged to ensure compliance
with national laws, standards and regulations
throughout the entire project and to take appropriate
additional or alternative workplace safety precau-
tions where necessary.
Hazard assessment
▪The customer is responsible for drawing up, docu-
menting, implementing and continually updating a
hazard assessment at every job-site.
This booklet serves as the basis for the site-specific
hazard assessment, and for the instructions given to
users on how to prepare and utilise the system. It
does not substitute for these, however.
Remarks on this booklet
▪This document can be used as general Instructions
for Assembly and Use (Method Statement) or be
incorporated into site-specific Instructions for
Assembly and Use (Method Statement).
▪The graphics, animations and videos in this doc-
ument or app sometimes depict partially assem-
bled assemblies and may require additional
safety equipment and/or measures to comply
with safety regulations.
The customer must ensure all applicable regulations
are complied with, even if they are not shown or
implied in the graphics, animations and videos pro-
vided.
▪Individual sections contain further safety
instructions and/or special warnings as applica-
ble.
Planning
▪Provide safe workplaces for those using the scaffold
(e.g. for when it is being erected/dismantled, modi-
fied or repositioned etc). It must be possible to get to
and from these workplaces via safe access routes!
▪If you are considering any deviation from the
details and instructions given in this booklet, or
any application which goes beyond those
described in the booklet, then revised static cal-
culations must be produced for checking, as well
as supplementary assembly instructions.
Regulations; industrial safety
▪All laws, Standards, industrial safety regulations and
other safety rules applying to the utilisation of our
products in the country and/or region in which you
are operating must be observed at all times.
▪If a person or object falls against, or into, the side-
guard component and/or any of its accessories, the
component affected may only continue in use after it
has been inspected and passed by an expert.

User Information Ringlock Introduction
5999817902 - 10/2022
Rules applying during all phases of
the assignment
▪The customer must ensure that this product is
erected and dismantled, reset and generally used for
its intended purpose in accordance with the applica-
ble laws, standards and rules, under the direction
and supervision of suitably skilled persons.
These persons' mental and physical capacity must
not in any way be impaired by alcohol, medicines or
drugs.
▪Doka products are technical working appliances
which are intended for industrial /commercial use
only, always in accordance with the respective Doka
User Information booklets or other technical docu-
mentation authored by Doka.
▪The stability and load-bearing capacity of all compo-
nents and units must be ensured during all phases of
the construction work!
▪Strict attention to and compliance with the functional
instructions, safety instructions and load specifica-
tions are required. Non-compliance can cause acci-
dents and severe injury (risk of fatality) and consid-
erable damage to property.
▪Sources of fire in the vicinity of the scaffold, specially
hatch decks with plywood top, are prohibited. Heat-
ers are permissible only when used correctly and sit-
uated a correspondingly safe distance from the scaf-
fold.
▪Customer must give due consideration to any and all
effects of the weather on the equipment and regards
both its use and storage (e.g. slippery surfaces, risk
of slipping, effects of the wind, etc.) and implement
appropriate precautionary measures to secure the
equipment and surrounding areas and to protect
workers.
▪All connections must be checked at regular intervals
to ensure that they are secure and in full working
order.
In particular threaded connections and wedged con-
nections have to be checked and retightened as nec-
essary in accordance with activity on the jobsite and
especially after out-of-the-ordinary occurrences (e.g.
after a storm).
▪It is strictly forbidden to weld Doka products – in par-
ticular anchoring/tying components, suspension
components, connector components and castings
etc. – or otherwise subject them to heating.
Welding causes serious change in the microstruc-
ture of the materials from which these components
are made. This leads to a dramatic drop in the failure
load, representing a very great risk to safety.
It is permissible to cut individual tie rods to length
with metal cutting discs (introduction of heat at the
end of the rod only), but it is important to ensure that
flying sparks do not heat and thus damage other tie
rods.
The only articles which are allowed to be welded are
those for which the Doka literature expressly points
out that welding is permitted.
Assembly
▪The equipment/system must be inspected by the
customer before use, to ensure that it is in an accept-
able condition. Steps must be taken to exclude com-
ponents that are damaged, deformed, or weakened
due to wear, corrosion or rot (e.g. fungal decay).
▪Using our safety and scaffolding systems together
with those of other manufacturers can create risks
that may lead to injury and damage to property. This
requires separate verification by the user.
▪The equipment/system must be assembled and
erected in accordance with the applicable laws,
standards and rules by trained customer personnel
whilst maintaining any applicable safety inspections
that may be required.
▪It is not permitted to modify Doka products; such
modifications constitute a safety risk.

6999817902 - 10/2022
Introduction User Information Ringlock
Transporting, stacking and storing
▪Observe all country-specific regulations applying to
the handling of scaffolding. For system scaffolding
the Doka slinging means stated in this booklet must
be used – this is a mandatory requirement.
If the type of sling is not specified in this document,
the customer must use slinging means that are suit-
able for the application envisaged and that comply
with the regulations.
▪When lifting, always make sure that the unit to be
lifted and its individual parts can absorb the forces
that occur.
▪Remove loose parts or secure them so that they can-
not slip out of position and drop.
▪When lifting scaffolding or scaffolding accessories
with a crane, no persons must be carried along, e.g.
on working platforms or in multi-trip packaging.
▪All components must be stored safely, following all
the special Doka instructions given in the relevant
sections of this document!
Maintenance
▪Only original Doka components may be used as
spare parts. Repairs may only be carried out by the
manufacturer or authorised facilities.
Miscellaneous
The weights as stated are averages for new material;
actual weights can differ, depending on material toler-
ances. Dirt accretions, moisture saturation, etc. can
also affect weight.
We reserve the right to make alterations in the interests
of technical progress.
Eurocodes at Doka
The permissible values stated in Doka documents
(e.g. Fperm = 70 kN) are not design values (e.g. FRd =
105 kN)!
▪It is essential to avoid confusing permissible values
with design values!
▪Doka documents will continue to state the permissi-
ble values.
Allowance has been made for the following partial fac-
tors:
▪γF= 1.5
▪γM, timber = 1.3
▪γM, steel = 1.1
▪kmod = 0.9
Consequently, all the design values for an EC design
calculation can be determined from the permissible val-
ues.

Safety Guidelines and Safe Use
The guidance given here is not intended to replace any
relevant local/regional standards, Company Proce-
dures, Work at Height Regulations and other legisla-
tion, but is a practical guide to good scaffolding practice
using Ringlock System scaffolding. Please refer to the
latest versions of EN 12810, EN 12811, the NASC
Guidance Notes and current legislation prior to starting
your work.
The assembly, modification or dismantling of the Rin-
glock system may only be carried out by professionally
qualified personnel ('authorized person'). The instruc-
tions and specifications of DIN 4420, EN 12811 and
DGUV Information 201-011 'Instructions for handling
work and protective equipment' as well as the regula-
tions of the technical rules for operational safety TRBS
2121 or any other local/regional specific rule must be
observed.
Before working on the Ringlock scaffold, a hazard anal-
ysis must be carried out considering the special fea-
tures of the individual case. The result must be
recorded in a risk assessment and the personnel must
be instructed. Particular attention should be paid to
technical protective measures against falls from a
height and to the measures required for possible res-
cue operations. If the use of personal protective equip-
ment against falls from a height (PPE) is required, the
information on anchor points in the relevant section
must be observed.
Damaged or improperly modified scaffolding compo-
nents must not be used and must be replaced immedi-
ately with sound material.
Scaffolding components should be stored and trans-
ported in such a way that the risk of damage is avoided.
Scaffolding components must not be thrown. If neces-
sary, the use of lifting equipment must be checked.
After completion of the assembly work and before each
use, an inspection must becarried out to ensure that the
equipment is in proper condition. Work may only be car-
ried out on approved and apparently faultless scaffold-
ing, see also the following sections.

User Information Ringlock Introduction
11999817902 - 10/2022
Safety Guidelines and Safe Use
▪Ensure that you follow your Company’s safe systems
of work at all times.
▪Ensure that your staff erecting, dismantling or modi-
fying any Ringlock scaffold are licensed to carry out
the task.
▪Ensure that all persons erecting, dismantling or mod-
ifying the scaffold structure are working to the latest
version of the applicable standards and current leg-
islation.
▪Ensure all Personal Protective Equipment (PPE) is
suitable and sufficient and worn as appropriate.
▪Consideration should also be given as to where addi-
tional hazards may be present whilst scaffolding
operations are taking place, such as overhead power
cables, roadways, schools and if public protection is
required, if the scaffold is to be sheeted, who is
responsible for the design.
▪Ringlock scaffold structures are recommended to be
inspected and recorded:
- Prior to being put into use for the first time
- After any alteration or adverse weather
- After any event likely to affect its stability
- Regular intervals as per site requirements or
Company procedures but generally not exceed-
ing 30 days
▪Access and egress should be considered as early as
practicable, for both the scaffold operatives and the
end user in mind. Ladders should be used by the
scaffolders when erecting, modifying or dismantling
any Ringlock scaffold. Ledgers and brace compo-
nents etc. must not be used as a means of support.
Ensure that access and egress routes including lad-
ders and stairways, are kept clear.
Below is the hierarchy of measures to consider when
selecting methods to prevent a person falling at
access and egress points:
- Install staircases
- Install ladder Access Bays with Single Lift Lad-
der
- Install ladder Access Bays with Multiple Lift Lad-
ders
- Install internal ladder access with protection i.e.
ladder trap/handrails etc.
- Install external ladder access using the Ringlock
adjustable Swing Gate
▪Employers have an obligation to ensure that Work at
Height is::
- Properly planned
- Appropriately supervised
- Done in a safe manner 'so far as is reasonably
practicable'
- Include planning for emergencies & rescue
- Weather conditions do not jeopardise health and
safety
▪Before allowing people or materials on the Ringlock
scaffold, ensure that it has been erected correctly
and complies with the specified requirements and all
applicable legislation.
▪Ensure that all people using the Ringlock scaffold
are aware of the purpose for which it is intended to
be used and the maximum loading to which it can be
subjected.
▪Ensure users understand that any unauthorised
modification to the Ringlock scaffold or removal of
components could cause a safety hazard. Alteration
or extensions should be carried out only by a
licensed person.
▪Provide barriers and warning notices to prevent
access to incomplete sections of scaffolding.
▪Do not overload and ensure that crane and forklift
drivers understand loading restrictions on each part
of the scaffold structure.
▪Because of the increased use of mechanical lifting
plant on site there is an increased possibility for scaf-
folding components to become fouled/caught. When
using cranes or other mechanical lifting devices near
any Ringlock scaffold care should be taken to ensure
that nothing catches under any part of the scaffold.
Otherwise uplift could occur with potentially danger-
ous consequences.
▪Pigtail Pins/ Toggle Pins or Standard Leg Locks are
available to positively fix standards together if your
Method Statement/Risk Assessment indicates that
uplift cannot be eliminated.
▪Scaffold access should be secured when not in use
to prevent unauthorised access onto scaffolding.
Ladders should be kept in a storage compound or
container.
▪Consider enclosing the base of the scaffolding to
prevent climbing, especially near occupied prem-
ises.
▪Consider the environment particularly with respect to
pedestrian and vehicle movements.
If you are in any doubt regarding any information con-
tained within this Safety Manual and User Guide,
please contact your local Doka representative.

Ringlock Overview
Ringlock Node Connection
Ringlock node connection consists of Standards with
rosettes every 0.5m and horizontal members with a
cast end captive wedge (Ledger and Transom). When
connected together the Ledger ends and rosettes cre-
ate a very strong connection. This connection transmits
the forces throughout the scaffold structure.
The Ringlock rosette has a diameter of 123mm and has
been manufactured with 8- trapezoidal slots, 4-small
and 4-large. The smaller holes represent the 90 degree
angle at the Ledgers and Transoms are installed. The
larger trapezoidal holes accommodate the Diagonal
Bay Braces.
If the needed, the Ledgers can be installed in the larger
holes, allowing up to 15-degrees of rotation. This pro-
vides added flexibility to clear obstacles when neces-
sary.
It is recommended that a 500g hammer is used to
secure the Ringlock wedge, when the hammer
rebounds, the wedge is secure.

Instructions for Scaffolding Construction
Thanks to the flexibility of the wedge connection, the
Ringlock modular scaffolding system can be used for
everything from simple façade scaffolding to complex
industrial support scaffolding. The relevant characteris-
tic values such as stiffness and load-bearing capacity
of the scaffolding system can be found in the approval
certificate Z-8.22-992.
Vertical Standard
The robust Ringlock is made of high-quality steel. For
maximum flexibility, rosettes are welded to the vertical
standards at 50 cm intervals, to which up to 8 compo-
nents can be connected using the widely used and
proven wedge connection.
Ringlock rosette
▪Each rosette has eight openings. The smaller open-
ings are generally used to help guide the scaffolding
to make 90 degree connections, whereas the larger
opening enable connections at variable angles to be
achieved.
▪Unless erecting a scaffold around a circular building
structure, align the Base Collar rosettes so that one
of the small openings in the rosette points in the
Ledger direction. The small openings at right angles
to the first will automatically align the Transoms at 90
degrees.
▪The larger openings are generally used for connect-
ing the diagonal braces.
Ringlock Ledger
The ledgers can be easily installed by sliding the tran-
som head onto the rosette and then wedging it in place.
The wedges are permanently connected to the ledger
and, as an assembly aid, allow a rigid connection to be
made even when the wedge is only loosely inserted.
Before the components are loaded, the tight fit between
the wedge and the rosette or vertical stem must be
achieved with a 500g hammer until impact is felt. The
disassembly of the ledgers is done in reverse order:
The wedge is loosened by hitting it from below with a
hammer and pulled out of the rosette by hand.

Color Coded Components
A new feature offered by Doka is the horizontal compo-
nents manufactured with a colourcoded identification
label. This process allows the scaffolder to easily match
particular components for each size of the bay to be
erected. (For example: An Green Ledger 2.57m will
work with an Green Diagonal and an Green Plank.)

Erection Guidelines
Recommendations
Prior to Erecting Ringlock the following is recom-
mended:
▪The job site should be inspected to ensure that the
ground or other supporting structure is strong
enough to safely support the self-weight of the scaf-
fold and the imposed loads on the platforms. In addi-
tion, please make yourself aware of the proximity of
power lines, overhead obstructions and weather
conditions. These could pose a possible danger dur-
ing the erection, use and dismantling of Ringlock and
should be evaluated and adequately addressed in
accordance with the requirements for provision of
Risk Assessments and Method Statements.
▪Check the condition of the building façade at the pro-
posed tie locations.
▪The spacing of the Standards should be in accord-
ance with the relevant layouts, if available.
▪If design drawings of the scaffold are required, check
the requirements of the local authority with respect to
what must be shown on the drawings (load rating,
erection/dismantling instructions etc.).
▪All equipment should be inspected prior to use to
ensure that it is in good condition and is serviceable.
Damaged or deteriorated equipment must not be
used.
▪Avoid storing or handling scaffold components below
or close to electrical power lines. Check the require-
ments of the authority having jurisdiction for the
exclusions zones.
▪Care must be taken when scaffolding work is in close
proximity to exposed and insulated electrical lines
and hidden electrical cables (for example, cable con-
cealed behind a surface where a scaffold anchor is
to be fitted).
▪Be aware of all Client and work related site safety
procedures as well as reference to local/regional and
National legislation.
▪Be aware of possible dangers regarding explosions
or fire.
▪Ensure that the scaffolders are trained and fully
instructed to erect Ringlock system scaffolding.
▪Check the safety and function of all the tools that are
used during erection.
