SAFETY MANUAL & USER GUIDES

Shallow 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 500mm below highest
ground level, set the Base
Jack adjusting handle 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 Standard 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:

4. 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.
5. 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.

6. Continue with the erection of Ringlock scaffold following items 1. to 3. above.
