12. Concrete and Anchoring:
A. Square up runways. Install spacer bar and bolts,
to help maintain the runway spacing, Fig. 14. Adjust
runways until diagonals are equal. Check lift location in
the bay. Check dimensions side-to-side, equal to within
1/8" (3mm), Fig. 15.
CAUTION
DO NOT install on asphalt or other similar
unstable surfaces. Columns are supported only by anchors
in floor.
B. Rear Column Install.
1. Move rear column towards yoke until the sliders
contact the back of column. Center yoke in column,
Fig. 16.
2. Place shims (estimated from Step 3) under each
column. Drill four 5/8" (16mm) diameter holes through
concrete floor using holes in baseplate as guide,
Fig. 17.
3. Insert anchors with washers, Fig. 17. 5/8" anchors
must have a minimum anchor embedment of 2-3/4"
(70mm). If the top of the anchor exceeds 1-1/2"
(38mm) above the floor grade, you DO NOT have
enough embedment.
4. Tighten 5/8" anchor bolts to an installation torque of
60 ft-lbs. (81 Nm). Shim thickness MUST NOT exceed
1/2" (13mm) when using the standard anchors
provided with the lift. Check columns for plumb.
Re-shim if necessary. Repeat for other column.
If anchors do not tighten to required installation
torque, replace concrete under each column base
with a 4' x 4' x 6" (1219 x 1219 x 152mm) thick 3000
PSI (20684 kPa) minimum concrete pad keyed under
and flush with the top of existing floor. Let concrete
cure before installing lifts and anchors.
Drill holes using carbide
tipped masonry drill bit per
ANSI B212.15-1994 (R2000)
C. Front Column Anchoring:
Clean hole.
Run nut down just
below impact section
of bolt. Drive anchor
into hole until nut and washer
contact base.

1. If necessary, readjust runways until diagonals are
equal. Remove Spacing Tool and reattach yoke/
runway bolts. Hold runway spacing at 43" (1092mm).
2. Position front column where both outer yoke
wheels are in contact with the column. Shim and
plumb front of column, taking care to push column
in to contact lower rollers. Push opposite column in
to contact rollers.
3. Drill six 3/4" (19mm) holes through concrete floor
using holes in baseplate as guide.
4. Insert anchors with washers, Fig. 18. 3/4" anchors
must have a minimum anchor embedment of 3-1/4"
(83mm). If the top of the anchor exceeds 2-1/4"
(57mm)above the floor grade, you DO NOT have
enough embedment.
5. Tighten 3/4" anchor bolts to an installation torque of
110 ft-lbs. (149 Nm). Shim thickness MUST NOT
exceed 1/2" (13mm) when using the standard
anchors provided with the lift. Check columns
for plumb. Re-shim if necessary. Repeat for other
column. If anchors do not tighten to required
installation torque, replace concrete under each
column base with a 4' x 4' x 6"
(1219 x 1219 x 152mm) thick 3000 PSI (20684 kPa)
minimum concrete pad keyed under and flush with
the top of existing floor. Let concrete cure before
installing lifts and anchors.
Tighten nut with
Torque wrench:
5/8" rear column
anchors 60 ft.-lbs.
(81 Nm)
3/4" front column
anchors 110 ft-lbs.
(149 Nm)
