Yoke Installation
NOTES
Do not use a single yoke as a template when multiple turnstiles
are installed, as yoke dimensions may vary slightly from yoke to
yoke.
NOTE
STEPS AND DIMENSIONS SHOWN
ARE FOR MST MODELS. SEE APPENDIX
A-D FOR OTHER MODELS.
1.
Reconfirm the centerline location for the yoke (Figure 7).
2.
Using a ⅝" concrete drill bit, drill an anchor hole 3" in
depth.
NOTE
The anchor hole(s) must be clean before installing the
anchor bolt(s). If the hole(s) are not clear of debris, the
anchor bolt(s) may not tighten correctly.
3.
Insert one anchor into the drilled hole (Figure 8A). The
threaded end of the anchor must be inserted into the hole
first. Use a hammer to tap the anchor into place, if needed.
Ensure that the anchor is flush with the concrete floor.
4.
Place the Yoke back over the anchor hole and anchor it with
one ⅜" x 4 ½" anchor bolt and flat washer .
NOTE
Prior to drilling the remaining anchor holes, use a tape
measure and measure the distance from the bottom bearing
plate center to the remaining mounting holes on the yoke
(Figure 7). Adjust the yoke until these two distances are
identical. Mark these two locations.
5.
Rotate the yoke to the left. Using a ⅝" concrete drill bit, drill
two anchor holes 3" in depth at the center of each marked
location.
6.
Insert two anchors into the drilled holes (Figure 8A). The
threaded end of the anchors must be inserted into the holes
first. Use a hammer to tap the anchors into place, if needed.
Ensure that the anchors are flush with the concrete floor.
7.
Rotate the yoke back over the anchor holes and anchor it
with two ⅜" x 4½" anchor bolt and flat washer (Figure 9).
8.
Once the yoke has been anchored, use a socket wrench
and 9/16" socket to tighten the anchor bolts (Figure 10).
9.
Confirm the yoke is level and plumb. Shim as needed.
