4.5 ASSEMBLY OF MID/LOWER PLATFORM END
STIRRUPS
(For stirrup model MLP1030D)
a. Always use a platform section with hatch (PMR1060D) at
one end of the platform assembly (adjacent to the ladder) if
the assembly is intended to be used as a mid level platform
of a Three-Level assembly. If the lower platform is to be
used in a Two-Level assembly the platform without a hatch
should be used.
WARNING!
A Platform Section with a hatch is not to
be used on the bottom tier of a multi-level
platform, unless the hatch is locked.
b. Align the Mid/Lower Stirrup and platform pinholes. Align
Section Horizontal Life Line Brackets as required. Install the
4-H-bracket connectors with the gravity lock pins from the
inside of the platform. Do not hammer or force the pins into
place. (see fig. 14)
c. Use only the supplied 5/8-inch diameter gravity lock pins.
Make sure that the pins are not worn, bent or otherwise
damaged.
Never substitute alternative pins or bolts
.
d. After each pin is installed, ensure that the gravity lock is
rotated closed and nearest to vertical to prevent the pin
dislodging. (see fig. 7 and 8 page 14)
4.6 CONNECTION OF MID/LOWER PLATFORM
ASSEMBLIES TO LADDER FRAME & LINK
HORIZONTAL LIFE LINE
a. Assemble or move the mid/lower platform below the
suspended upper assembly. Use the hoists to adjust the
height of the upper assembly so that the ladder frames are
level with or just below the pinholes at the top of each
Mid/Lower Platform End Stirrup. (see fig. 15)
b. Swing the Ladder Frames so that they are in line with the
pinholes at the top of each Mid/Lower Platform End Stirrups.
The Vertical Life Line should be hanging connected at the
top of the Ladder Frame. Insert the lower Vertical Life Line
Bracket between the Mid/Lower Platform End Stirrup
pinholes and the lower clevis of the Ladder Link.
c. Secure mid/lower platform and Link Horizontal Life Line with
the 4 provided Gravity Lock Pins. (see fig. 8 and 9 page 14)
d. Use only the supplied 5/8 inch diameter Gravity Lock
Pins. Make sure that the pins are not worn, bent or
otherwise damaged.
Never substitute alternative pins or
bolts.
