ditionalhazardsmaybepresentwhilstsca󰀨olding
operationsaretakingplace,suchasoverheadpow-
ercables,roadways,schoolsandifpublicprotection
isrequired,ifthesca󰀨oldistobesheeted,whois
responsible for the design.
▪ Ringlocksca󰀨oldstructuresarerecommendedtobe
inspected and recorded (tagging system):
- Priortobeingputintouseforthersttime
- After any alteration or adverse weather
- Afteranyeventlikelytoa󰀨ectitsstability
- Regular intervals as per site requirements or
Companyproceduresbutgenerallynotexceeding
7 days
▪Access and egress should be considered as early
aspracticable,forboththesca󰀨oldoperativesand
the end user in mind. Ladders should be used by
thesca󰀨olderswhenerecting,modifyingordis-
mantlinganyRinglocksca󰀨old.Ledgersandbrace
components etc. must not be used as a means of
support. Ensure that access and egress routes in-
cludingladders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 Ladder
- 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

cesstoincompletesectionsofsca󰀨olding.
▪Do not overload and ensure that crane and forklift
drivers understand loading restrictions on each part
ofthesca󰀨oldstructure.
▪Because of the increased use of mechanical lifting
plant on site there is an increased possibility for
sca󰀨oldingcomponentstobecomefouled/caught.
When using cranes or other mechanical lifting devic-
esnearanyRinglocksca󰀨oldcareshouldbetaken
to ensure that nothing catches under any part of the
sca󰀨old.Otherwiseupliftcouldoccurwithpotentially

ErectionGuidelinesforRinglockSca󰀨old
Recommendations
Prior to Erecting Ringlock the following is recommend-
ed:
▪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 ad-
dition,pleasemakeyourselfawareoftheproximity
ofpowerlines,overheadobstructionsandweather
conditions. These could pose a possible danger
during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
proposed tie locations.
▪The spacing of the Standards should be in accord-
ancewiththerelevantlayouts,
if available.
▪ Ifdesigndrawingsofthesca󰀨oldarerequired,
check the requirements of the local authority with re-
spect 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sca󰀨oldcomponentsbe-
low or close to electrical power lines. Check the re-
quirements of the authority having jurisdiction for the
exclusionszones.
▪ Caremustbetakenwhensca󰀨oldingworkisin
closeproximitytoexposedandinsulatedelectrical
linesandhiddenelectricalcables(forexample,
cableconcealedbehindasurfacewhereasca󰀨old
anchoristobetted).
▪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re.
▪ Ensurethatthesca󰀨oldersaretrainedandfullyin-
structedtoerectRinglocksystemsca󰀨olding.
▪Check the safety and function of all the tools that
are used during erection.
Risk Assessment
Prior to Starting Erection Conduct a Risk Assessment
A risk assessment is simply a means of determining
what could cause harm within your workplace and
developing suitable control measures to prevent ac-
cidents. It is also a legal requirement and you have
duties under HSE legislation.
BeforestartingerectionofRinglocksca󰀨olding,we
would recommend you consider the following:
▪ Ensurethatallsca󰀨oldershaveseentheriskas-
sessment and ensure that they understand it.
▪ Ensurethatallsca󰀨oldingworkerssigntheriskas-
sessment form.
▪ Doublechecktheworksite,ensurethatallsca󰀨old-
ing workers have checked their tools.
▪ Securetheworkarea,isolatefromothersandes-
tablish drop zones.
▪Consider the job at hand and ensure that nothing
has been missed.
▪Never be taken in by the “Big Risk” and miss other
potentialproblems(suchastriphazards,people
workingnearby,possibilityofdroppingobjectsetc.)
Onceyoustarttheerectionwork:
▪Never work outside the scope of the Risk Assess-
ment.
▪Always stop work and re-assess if conditions
changeorifadditionalhazards,whicharenotin-
cludedintheRiskAssessment,becomeapparent.
▪Always stop work if you feel unsafe.

Sca󰀨oldingErectionGuidelines
Step 1
➤Preparethefoundationforthesca󰀨old.
➤InstallBaseCollarsontheAdjustableBaseJacks,
and set them out roughly in position with their cor-
responding Ledgers. Pick the highest ground level
for the starting point to simplify later adjustment. It
helps if the Base Jack adjusting handle is near the
bottomofthethread.Thiswillallowmaximumad-
justment on the lower ground levels.
➤The Base Jack must be located centrally on
sole plates boards.
➤Forlevelsurfaces,startatoneendwherethescaf-
foldisrequired,andbuildtowardstheotherend.
SettheBaseJackaslowaspossible.Onlevelsur-
faces,theyshouldallbeatapproximatelythesame
height.
➤Each rosette has eight openings. The smaller
openings are generally used to help guide the scaf-
foldingtomake90degreeconnections,whereas
the larger opening enable connections at variable
angles to be achieved.

➤Unlesserectingasca󰀨old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rstwillautomaticallyaligntheTransomsat
90 degrees.
➤The larger openings are generally used for connect-
ing the diagonal braces.

Step 2
➤Connect the Ledgers to the rosette on the Base
Collar. Do not hammer in the wedges at this stage.
➤Usingaspiritlevel,adjusttheJackssothatthe
Ledgers and Transoms are horizontal. Accuracy in
leveling at this stage eliminates the need for further
levelingplumbingasthesca󰀨oldiserected.

Detail of Plank connection
➤Place Planks of the correct bay length into the end
bay to fully deck out the bay. Adjust the position of
the Jacks and Base Collar by pushing one Jack
sideways either in or out in order that the Planks
areparallelwiththeLedgers.Onlyasmallamount
of movement may be needed to ensure the bay
is square enough to lock down the Planks with
DeckLocks.Onceyouaresatisedthatthebayis
square,llallotherbayswithPlankssothataplat-
formiscreatedfromwhichtherestofthesca󰀨old
can be erected.
➤Whenyouaresatisedthatthesca󰀨oldisfully
squaredandlevelled,hammerinthewedges.
Sca󰀨oldingNote:
Irrespective of whether a platform is required on the
lowest rosettes it is recommended that the Planks are
installedatthislevel.Thisensuresthatthesca󰀨oldis
square and level prior to erection and it also provides
plansti󰀨ness.Thisismostimportant,especiallywhen
themaximumheightofthesca󰀨oldisaboveeightlifts.
The installation of these Planks ensure that the out
of alignment eccentricities are kept to a minimum in
orderforthesca󰀨oldtoattainthemaximumpermissi-
ble height for each recommended tie pattern (refer to
Technical Manual).
