Step 3: Assembly of vertical column, Figure #3, and lower beam, Figure #2, to base assem-
bly, Figure #1.
a.) Lift the coupled vertical column and lower beam assembly by attaching to verti
cal column. Lift high enough to clear the base assembly and move directly over
the base assembly.
b.) Lower the vertical column and lower beam until the outriggers, Figure #5, can be
attached to the base and vertical column.
c.) Before installing the outriggers place the six (6) M20x46x100 bolts, item 13 , with
six (6) 3/4" flat washers, item 54 , through the holes on the rear flange of the
vertical column. These bolts will be used to attach the cylinder mount during a
later step in the assembly instruction. These bolts must be placed with the
threads pointing toward the rear of the load tester and must be inserted prior to
the installation of the outriggers to avoid interference.
d.) Fix both outriggers into position using four (4) M16x65mm long bolts, item 16 ,
pushing through the lower attachment holes of the outriggers and through the
attachment holes on the base. Secure the outriggers by placing M16 "U"
washer, item 34 , and M16 nuts, item 19 , as shown on drawing 50979. Do not
tighten these nuts until the remainder of the attachment bolts have been placed
in the upper holes of the outriggers.
e.) Align the upper holes of the outriggers and the vertical column attachment holes
by using a drift punch until the four (4) M16x65mm long bolts, item 16 , have
been placed through the alignment holes at the top of the outrigger shown in
drawing 50979. Secure the four (4) bolts with M16 flat washers, item 17 , lock
washer, item 18 , and nuts, item 19 .
f.) Make certain that all M16 fasteners are tight by applying 187 foot-lb of force
using a torque wrench.
