Roller Track Installation - Without Embed - TPR UniLock Owner & User Manual

INSTALLATION

Roller Track Installation - Without Embed

Do not install the UniLock vehicle restraint directly
onto a concrete block or brick dock face; contact
Systems, LLC to purchase a suitable Z-bracket.
Minimum 4" thick bumpers are required at all
positions where a UniLock vehicle restraint is
installed. DO NOT install on docks without minimum
4" thick bumpers. For thicker bumpers, consult the
factory.
Note: Walls must be poured concrete, 8" thick
minimum to install with wedge anchors. Concrete
block or brick is not acceptable.
Install roller track plate onto dock face at specified
location by using the fifteen (15) concrete anchors
provided, in conjunction with welding to pit steel or a
leveler frame. If required, roller track can be trimmed
up to a maximum of 5" from the bottom.
The roller track plate must be plumb with the dock
face. If not, use and weld (6) shims 2" wide x 25-
5/8" long. Shims must be the full length of the roller
track mounting plate. If shims are over 1/2" thick, use
longer anchors. If shims need to be 1" thick or more,
contact Systems, LLC Technical Services.'
Some levelers are slightly recessed within the pit and
thus require a shim to be inserted between the roller
track plate and the leveler front subframe and welded
in place.
Note: Some mechanical dock levelers have an
adjusting nut access hole in the leveler front
subframe. If the TPR vehicle restraint roller track
interferes with the access hole, the track plate must
be cut to allow access.

Anchor Installation
Note: Fifteen (15) concrete anchors are provided
with each TPR vehicle restraint. An anchor must be
installed in each roller track plate hole except for
those plug-welded to embedded steel.
1. Place roller track at desired location, spaced 5/8"
above the drive.
2. Using the roller track as a guide, drill holes of
5/8" diameter and minimum of 4-5/8" deep at all
locations where roller track is not overlapping
curb steel. Clean out holes.
3. Insert anchors and drive them flush with roller
track plate, making sure that the threaded wedge
is inserted first. Do not disassemble anchors prior
to installation.
4. Once all anchors are installed, torque to 60 ft-lbs.
Welding Instructions
Note: If the installation being worked on is a retrofit
or replacement, make sure that the power source
has been tagged and locked out according to OSHA
regulations and approved local electrical codes, then
remove the motor and limit switch connections from
the control harness located in the outside junction
box.
1. Disconnect power and ground leads to dock
leveler (if equipped).
2. Plug weld all holes that are in contact with
embedded steel. All fifteen (15) holes must
be either plug welded or anchored. Minimum
electrode must be 1/8" 7018 or better.
3. Weld across top of roller track plate to curb steel
or leveler frame with 3" long 1/4" fillet welds.
4. Once all welding has been completed, reconnect
power and ground leads to dock leveler (if
equipped).
5. Clean and touch up all welds once complete.
