Scaffold
User Information
Ringlock
Ground Adjustment
The base setup of the scaffold should be started at the
highest point of the ground level. The base jacks are
placed on the ground and installed with longitudinal and
transverse ledgers at the base lift. The jack spindle
should be located about 5cm above the floor to provide
adjustability to extend in lower areas.
If the maximum spindle extension length of the jack is
not sufficient for horizontal alignment of the longitudinal
ledgers, additional vertical uprights must be used to
compensate for the difference in height. Additional lon-
gitudinal and transversal ledgers are required to pro-
vide the sufficient stiffness by installing 50 cm below the
higher adjacent scaffold bay. The rest of the framework
is erected as described in the section 'Erecting a facade
framework'.
Slopes
Shallow Slopes
1)
Pick the highest ground level for the starting point
to simplify later adjustment. Start with the Base
Jack adjusting handle as near as possible to the
bottom of the thread. This will allow maximum
adjustment as the ground drops below the level of
the first Sole Board.
2)
When the ground is more than 500
mm
below
high-
est ground level, set the Base Jack adjusting han-
dle near to the bottom of the thread and fit the Base
Collar. Introduce a Standard and wind up the thread
on the Base Jack until the second rosette in the lift
is level with the previous Standard. Introduce the
Ledger to fix the Base jack, base Collar and Stand-
ard in place.
3)
Continue down the slope positioning the adjusting
handle on the Base Jack such that the Ledger
always engages with the nearest Rosette to allow
the Ledger to be level.
Steep Slopes
➤
Depending on the nature of the ground and the
steepness of the slope it may be necessary to use a
Swivel Jack where the base plate can rotate to any
angle up to 90 degrees.
➤
It may be more appropriate to place scaffold boards
continuously up the slope in place of an individual
Sole Board. The Swivel Jacks may be fastened to
this with suitable screws to avoid any slip between
the two surfaces.

NOTICE
When erecting scaffolds on soil (excavatable
surfaces) prepare a level base by removing
sufficient soil to completely fit the Mudsill.
Consider the surface type and the scaffold sills
to determine if anchorage between the two is
necessary.
