4.3 ASSEMBLY OF UPPER PLATFORM END STIRRUPS
AND HOISTS
(For stirrup model MLP1011D )
a. Always use a platform section with hatch (PMR1060D) at
one end of upper level platform assemblies (adjacent to
the ladder).
b. Align the upper platform stirrup and platform pin holes.
Align horizontal lifeline 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. 11)
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. 12)
e. Bring a hoist to the top of the end stirrup. Attach the
hoist to the stirrup saddle using mounting hardware
provided by your supplier.
f. Install secondary suspension rope.
g. Repeat the stirrup installation on the opposite end of the
platform.
h. When a platform with a hatch is not required for access
install the lock on the hatch.
4.4 ASSEMBLY OF LADDER FRAME & VERTICAL LIFE
LINE ON TO UPPER PLATFORM END STIRRUPS
(For Ladder Frame part # MLP1021C, MLP1022C &
MLP1023C and link vertical life line PMR0037B,
PMR0038B & PMR0039B)
a. Always use a platform section with hatch (PMR1060D) at
one end of upper level platform assemblies (adjacent to
access ladder).
b. Connect Ladder Frames of matching lengths to the
bottom of the upper platform End Stirrups. Align each
clevis at one end of the frame with the corresponding pin
holes located at the bottom of each stirrup. Install Vertical
Life Line Bracket at the top of one side of the access
ladder section. Secure with provided Gravity Lock Pins.
(see fig. 13)
c. With operators on the assembled upper platform at each
hoist location and connected to the Horizontal Life Line
with lanyards and full body harnesses, use the hoists to
raise the upper platform so that the ladder frames hang
freely. Adjust the height of the platform so that the bottom
clevis of each Ladder Link is just below the pin hole
height of the lower assembled platform Mid/Lower End
Stirrups.
d. Use only the supplied 5/8 inch diameter Gravity Lock
Pins. Make sure that the pins are not worn, bent or other-
wise damaged.
Never substitute alternative pins or
bolts.
WARNING
Never set the Multi-level Platform down and
remove tension from wire ropes. The Multi-level
platform may collapse!
