Ladder Access
Ladder Access
This is the ladder access solution that is most often
used. It involves installing inclined ladders within the
sca󰀨oldandsecuringthemtoalongitudinalLedger
near the bottom and to the Guardrail at the top. Meth-
ods of securing the ladder may include the use of
Doka ladder clips/hooks.
The ladder bay is usually erected at the same time as
theaccesssca󰀨oldandisbuiltfollowingtheSca󰀨old
Erection Guideline Steps. The opening in the plat-
form to receive the ladder is formed using a Ledger
to Plank Transom and generally a Plank that is half
the length of the bay. The usual opening width is two
Planks and the opening should be at least 1.00m
along the length of the platform to allow safe access
up and down the ladder.
Ladders should be inclined at a 1 in 4 slope. It is
recommended that the top part of the ladder should
extend1000mmabovethelandingplatformtoallow
easyaccessonando󰀨therungs.
Ladder Hatch Deck
Alternatively a ladder hatch deck can be used to pro-
videaccessinexternalladdertowersorwherespace
is a premium on a site the ladder hatch deck can be
incorporatedintothemainsca󰀨old.
The Ladder hatch deck replaces 2No standard 0.32m
decks.
The component compromises a manual opening and
closing hatch that is locked when closed and can
be unlocked from above or below the platform level
allowing access to the ladder and the ladder locking
mechanism.
The ladder can be locked in the horizontal plane im-
mediately below the hatch deck allowing safe passage
below.
