PLATFORM EXTENDERS
Except for being smaller, platform extenders are the same as standard platforms. They are intended
to allow end loops to be used on both sides of a ramp without impeding the walking area of an
adjacent platform or landing. Platform extenders are available in two sizes: 4-1/2-ft x 1-ft (for 48”
wide ramps) and 5-ft x 1-ft (for 54” wide ramps) and are available with either picketed guards or
two-line rails. If a 5-ft x 1-ft platform extender is used on a 5-ft platform side, no closure is required.
Otherwise, special platform extender closures are available (in both picketed guards and two-line
rails) for the specific combination of platform extender and the platform side to which it will be
attached.
7.3.1.
Install legs in the platform extender and set at the desired height (as described in
‘PLATFORMS’ section), including bracing the legs if required for the height, and then
set the long side next to the main platform in the desired location.
Always use four legs in the platform extender even if the extender is being used
with a platform connector.
7.3.2.
Install a ramp hanger pair on the side of the platform extender opposite the main
platform and set the ramp end in the hangers per ‘INSTALL RAMPS ON PLATFORMS’
section.
7.3.3.
Install picketed guards or two-line rails on the 1-ft. sides of the platform extender as
described in ‘ASSEMBLE TWO-
LINE PLATFORM RAILS AND PICKETED GUARDS’ and
‘INSTALL TWO-
LINE PLATFORM RAILS AND PICKETED GUARDS’
sections.
7.3.4.
Install end loops in the ramp handrails as described in ‘INSTALL RAMP HANDRAIL END
LOOPS’ section (or ‘INSTALL RAMP HANDRAIL END LOOPS WITH LOWER (CHILD)
HANDRAILS’ section if lower handrails are present). FIG. 7.6 shows the installation at
this stage.
7.3.4.1.
Platform extender closures are installed in essentially the same manner as
other closures, except there is no adjacent ramp so the barrier attachment
plate and spacer are not used. Refer to ‘INSTALL TWO-LINE PLATFORM
RAILS AND PICKETED GUARDS’ and ‘CLOSURES’ sections
for installing the
platform angle post in the open platform corner pocket.
7.3.4.2.
Refer to ‘HANDRAIL CLOSURES’ section for installing a two-line rail closure
or picketed guard closure.
