SAFETY PRACTICES

5609 RS 01/17 PAGE 4
©2017 4Front Engineered Solutions, Inc. - APS Resource
MOUNTING CONSIDERATIONS
1. The dock face on which the APS 2000 Vehicle
Restraint will be mounted must be at and vertical
to prevent binding of carriage assembly. If the dock
face is not at and vertical, it may be necessary to
use shims or physically modify the dock face. Consult
APS Resource for shimming requirements.
2. The anchors provided with the APS 2000 Vehicle
Restraint must only be used on docks constructed
of solid concrete, 4000 psi minimum strength,
6-1/2” minimum thickness. Docks constructed with
other materials, such as brick or block, require
special mounting consideration, which may include
brackets and a solid concrete approach. Consult
APS Resource if the dock does not meet concrete
requirements.
3. Do not install the APS 2000 Vehicle Restraint anchor
bolts into aged or unsound concrete.
4. If the driveway beneath the Vehicle Restraint is
affected by frost, additional clearance may be
required between the Vehicle Restraint and the
driveway to prevent damage.
TOOLS REQUIRED
- Welder
- Impact or rotary drill with 5/8" diameter concrete drill bit
- 3/4" wrench
- General hand tools
- Touch up paint (Gold)
- Torque wrench (60 ft-lb min.)
Before installation read and follow the Safety
Practices. Failure to follow these safety practices
could result in death or serious injury.
READ AND FOLLOW THE OPERATION
INSTRUCTIONS IN THIS MANUAL BEFORE
OPERATING THE APS 2000®VEHICLE RESTRAINT.
If you do not understand the instructions, ask your
supervisor to teach you how to use the Vehicle
Restraint.
Improper installation of the APS 2000®Vehicle
Restraint could result in death or serious injury to
dock workers or other users of the Vehicle Restraint.
Place barricades around pit on dock oor and
driveway while installing, maintaining or repairing the
vehicle restraining device.
Be certain bystanders in the driveway stand clear
when the Vehicle Restraint is operated.
Be certain to follow the installation instructions in
this manual.
Do not install the Vehicle Restraint anchor bolts into
aged or unsound concrete.
5. Vehicle Restraints require a minimum 4" bumper
projection from the front of the bumper to the rear
of the roller track plate of the restraint (the mounting
surface). Less than 4" of projection can allow the
vehicle RIG to damage the restraint.
6. Bumper projection in excess of 4", from the front of
the bumper to the mounting surface, may reduce
the horizontal hooking range of the Vehicle Restraint
depending on driveway and dock conguration.
Use shims to optimize the horizontal hooking range
as needed. Consult APS Resource for shimming
requirements.
7. For bumper projections of 5-1/2" and greater, APS
recommends the use of a mounting bracket. Consult
APS Resource for bracket requirements.
8. A standard installation of the APS 2000 Vehicle
Restraint requires a 26" minimum dock face height
for mounting. If the dock face height is less than 26",
a pit oor mounting plate or mounting bracket may
be required. Consult APS Resource if the dock face
height is less than 26".
9. For installation of Vehicle Restraints with EOD
type docklevelers or any other special site-
specic mounting considerations not covered in
this manual, consult APS Resource at 262-518-
1000.

6. Anchor the roller track plate to the dock face using
the (15) 5/8" dia. x 4" long anchors provided. The
anchor bolts must be torqued to 60 ft-lbs to achieve
maximum holding strength. See Figure 3. If the top
portion of the roller track plate is in contact with the
front pit curb angle, weld across the top of roller track
plate to the curb angle.
7. If the APS 2000 vehicle restraint is being installed at
a loading dock with a pit-style dockleveler that does
not have lip storage supports (otherwise known as
lip keepers), there is a bolt-on lip deector gusset kit
(P/N AP5664) included with the APS 2000. This kit
must be installed to prevent a pendant dock leveler lip
from moving or storing behind the original lip deector
welded to the right-hand spring cover. See Figure 4B
for installation.
8. Install additional lip deector plates, as required by
the application. Materials supplied by the installer.
See Figure 4A.
4. Check to see if the roller track plate is plumb and
ush with dock face. Add shims as required.
5. If shims are required, use (6) shims 2" wide x 25 5/8"
long, and install as shown in Figure 4a. Shims greater
than 1/2" thick require that longer anchors are used
for anchoring the APS 2000 Vehicle Restraint. For
shims greater than 1" thick, a mounting bracket must
be used instead. Consult APS Resource for longer
anchors or mounting bracket requirements.
TYPICAL ALONG SIDES
& BETWEEN HOLES
TOP VIEW
The anchor bolts should be installed as the holes are
drilled to prevent the Vehicle Restraint from shifting.
The anchor bolt heads must be tightly secured
against the roller track plate to prevent interference
with the carriage assembly.
INSTALLATION
Improper installation that allows a pendant dock
leveler lip to be supported by the restraint could
result in death or serious injury. It is sometimes
necessary to install lip deector plates as indicated
in Figure 4A to avoid any chance of the pendant lip
storing on top of or behind the roller track plate.

When lifting the carriage during service or assembly,
use a lifting device. Lifting by hand may result in
back injury.
Do not service this product unless you have read
and followed the Safety Practices, Warnings, and
Operation instructions contained in this manual.
Failure to follow these safety practices could result in
death or serious injury.
Check the lights to be certain they are returned to
the proper display. If no vehicle is at the dock, or
the vehicle is not hitched, the red inside light should
be illuminated and the green outside light should
be illuminated. If a vehicle is at the dock and is
hitched or the wheels are chocked, the green inside
light should be illuminated and the red outside light
should be illuminated.
Before doing any electrical work (including changing
bulbs), make certain the power is disconnected and
properly tagged or locked off.
Place barricades around the pit on the dock oor and
driveway while installing, maintaining or repairing the
dockleveler or the vehicle restraint.
Before working on or around the Vehicle Restraint,
visually conrm that the carriage assembly is at the
top of its travel range. If not, STOP; do not work
on or around the Vehicle Restraint. If the Vehicle
Restraint is not at the top of its travel range, it may
be due to an obstruction in the roller track. Under
this condition the springs may be under considerable
tension. Without properly securing the carriage
assembly, the Vehicle Restraint is unsafe to work on
or around. Call an approved and qualied technician
familiar with the APS Resource line of products. For
a list of approved and qualied technicians call APS
