Installation Manual
INSTALLATION CONT.
ANCHOR TRACK
1. Put DOK-LOK vehicle restraint track in place.
2. Drill holes of 5/8" diameter and minimum of 4-1/2"
deep. Clean out holes.
3. Insert anchor and drive flush with roller track plate,
making certain that the threaded wedge is put in first.
Do not disassemble anchor prior to installation.
4. Torque all anchors to 100 ft-lbs.
5.
Remove track cover plate and weld top of track to
leveler front frame angle and/or pit steel.
WELD TRACK
If the installation being worked on is a “reinstallation”
electrical connections must be disconnected prior to
welding. Make sure to LOCKOUT/TAGOUT the power at
the fused disconnect, then remove sensing switch
connections from control box. Once all welding
procedures have been completed, reconnect all wires.
1.
Put DOK-LOK vehicle restraint track in place.
2.
Plug weld all holes that are in contact with
embedded mounting plate. All holes must be either
plug welded or anchored.
3.
Remove track cover plate and weld top of track to
leveler front frame angle and/or pit steel.
NOTES
:
a.
Figure 2 – Never install DOK-LOK vehicle
restraint directly onto concrete block or brick
dock face.
b.
Figure 2 – When welding DOK-LOK vehicle
restraint, disconnect power and ground leads to
leveler.
c.
Figure 2 – Due to actual conditions, total
mounting height may be different. Refer to RITE-
HITE Application Guidelines for actual mounting
height.
d.
If shims are required, shims must be the full length
of the roller track mounting plate and base plate.
See page 13.
e.
Minimum electrode must be 1/8", 7018 or better.
DO NOT weld in enclosed areas without proper
ventilation.
BEFORE WELDING:
It is recommended that all power, ground and
limit switch wires are disconnected from the
sensor wires at the junction box. When welding
has been completed, reverse the above process.
Concrete anchors are provided with each
STR-4100 DOK-LOK vehicle restraint. You must
install an anchor in each roller track plate hole
except those plug-welded to embedded steel.
