a.) Remove the lower beam assembly, Figure #2, from the shipping crate using a
forklift or bridge crane.
b.) Locate the lower beam assembly securely on heavy blocks to allow approxi
mately 4" of clearance between the bottom of the lower beam and a smooth flat
surface preferably a concrete floor, as shown in Figure #2.
c.) Select three long pins, item 7 , and one orange colored size 1 1/4" master link,
item 10 , and one yellow colored size 1" master link, item 9 . Also select six (6)
M8x60mm long bolts, item 32 , and six (6) M8 lock nuts, item 33, all shown on
drawing 50979. Insert two (2) of the long pins in the pin holes labeled 5 ton and
10 ton, sliding them partially through the lower beam. Place the orange 1 1/4"
master link on the pin at the 10 ton location and the yellow 1" master link on the
pin at the 5 ton location. Now slide the pins the remainder of the way through
the lower beam and secure them by placing the M8x60mm long bolt with lock nut
at each end of the two pins, as shown in section A-A on drawing 50979.
d.) Remove the vertical column, Figure #3 from the shipping crate using a forklift,
trolley/hoist, or bridgecrane.
e.) Orient the vertical column in a vertical position with the attachment pin hole at
the bottom and the attachment angle in a position pointing toward the front of the
lower beam. See Figures 2 and 3.
f.) Lift the vertical column high enough to clear the lower beam and center the
attachment pin hole in the vertical column directly above the attachment hole for
the vertical column in the lower beam.
g.) Lower the vertical column down between the two horizontally oriented channels
of the lower beam and align attachment holes between the beam and the
column.
h.) Slide the third long pin, item 7 , drawing 50979 through the attachment holes
coupling the beam and column together. Install M8x60mm long bolts, item 32 ,
and 8 lock nuts, item 33 , as shown in section A-A on drawing 50979.
i.) Slide two pieces of 2"x6"x18" long wood through the opening between the rear of
the vertical column and the rear of the lower beam allowing them to bottom on
the floor and extend vertically upward along the column. See Figure #4 below.
These blocks of wood will prevent the lower beam from rotating about the attach-
ment pin.
