Locking Pawl Assembly
13) Install the locking pawl, actuator, and spring (
Fig.
4
). Adjust air cylinder clevis to retract lock against
inside of back of column when air cylinder is fully
extended. Tighten air cylinder clevis jam nut
against clevis.
A
NCHORING
Note:
•
The anchor bolts must be installed at least 8” from
any crack, edge, or expansion joint. Recheck the
area around both base plates.
•
Use a concrete hammer drill with a 3/4 inch carbide
bit. Tip diameter should conform to ANSI Standard
B94.12-1977 (.775 to .787). Do not use excessively
worn bits or bits, which have been incorrectly
sharpened. A core bit may be necessary if an
obstruction is encountered.
Never substitute with
shorter anchor.
14) Recheck “Inside of Columns” dimension (
Fig. 1
).
15) Using the base plate as a template, drill one
anchor hole. Drill through the floor if possible or to
a depth of 5 inches minimum.
16) Clean the hole inside and out.
17) Assemble a washer and nut to the anchor with nut
just below impact section of bolt. Drive the anchor
into the hole until the nut is 3/4” above the
baseplate (leaving room for shims).
Complete steps 15 thru 17 for the seven (7)
exposed anchors (one at a time) around each
column.
18) Raise both carriages (400 lbs. ea.) high enough to
drill the two inner anchor holes on each column.
Measure both carriage heights to ensure they are
in the same lock position.
19)
IMPORTANT
:
Place a safety support inside each
column as a backup to the locks since the
hydraulic cylinders are no longer engaged with
the carriages.
20) Repeat steps 15 thru 17 for the two (2) anchors
under each carriage.
21) Shim both columns to plumb using the shims
provided as shown in
Fig. 5
. DO NOT shim more
than 1/2" at any given point. Use a level no less
than 24” in length to plumb columns.
22) Drive all the anchors until nut and washer contact
baseplate.
Fig. 5 –
Column Shimming
23) Tighten Power Column anchors and recheck
column for plumb. Re-shim if necessary. Torque
to 150 foot pounds to set anchors.
24) Loosen Idler Column anchors 1/8” and proceed
with the Overhead Beam installation.
O
VERHEAD
25) Before raising overhead into position, install 4 (2
per column) hex flange bolts and nuts in bottom
hole of column extension tab
(see Fig. 6
Installation Aid)
for temporary support of
overhead. Lift overhead assembly up into position
and install with 8 (4 per column) 1/2-13 x 1” lg hex
flange bolts and hex flange nuts per side as
shown in
Fig. 6
. For the wide position, the outer
overhead holes will be used. For the 6” reduced
width, use one set of outer overheard holes and
one set of inner overhead holes. For the narrow
width, use the inner sets of overhead holes.
