Bay width
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).
