TABLE OF CONTENTS
INTRODUCTION
Read and understand this manual before attempting to install or operate any DOK-LOK vehicle restraint. For best
results, have this product serviced by your authorized Rite-Hite representative. The VBR-600 DOK-LOK vehicle
restraint by Rite-Hite is intended to provide a safer workplace for workers in shipping and receiving dock areas. The
VBR-600 DOK-LOK vehicle restraint is a hydraulic restraint device that, when properly installed and operated, retains
a secure connection between the truck and dock. Signal lights and signs provide instructions to the truck driver and
DOK-LOK vehicle restraint operator that a safe condition exists. The DOK-LOK vehicle restriant is operated by
pressing push buttons on an inside control panel.
NOTICE TO USER
Your local Rite-Hite representative provides a Planned Maintenance Program (P.M.P.) which can be fitted to your
specific operation. Call your local representative or Rite-Hite at 414-355-2600.

SAFETY WARNINGS
XXXXXXXXXXXX
XXXXXXXXXXX
OPERATE
DO NOT
LOCKOUT/TAGOUT PROCEDURES
The Occupational Safety and Health Administration requires that, in addition to posting safety warnings and
barricading the work area, the power supply has been locked in the OFF position or disconnected. It is mandatory
that an approved lockout device is utilized. An example of a lockout device is illustrated. The proper lockout
procedure requires that the person responsible for the repairs is the only person who has the ability to remove the
lockout device.
In addition to the lockout device, it is also a requirement to tag the power control in a manner that will clearly note
that repairs are under way and state who is responsible for the lockout condition. Tagout devices have to be
constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to
deteriorate or become unreadable.
Rite-Hite Corporation does not recommend any particular lockout device, but recommends the utilization of an
OSHA approved device (refer to OSHA regulation 1910.147). Rite-Hite Corporation also recommends the review and
implementation of an entire safety program for the Control of Hazardous Energy (Lockout/Tagout). These regulations
are available through OSHA publication 3120.
This is the highest level statement. Failure to
follow the listed instructions will most likely
result in severe injury or death.
IMPORTANT is used to draw attention
to a procedure that needs to be followed to
prevent machine or property damage.
When working with electrical or electronic
controls, make sure that the power source has
been locked out and tagged according to OSHA
regulations and approved local electrical codes.
This is a statement of serious hazard. Failure to
follow the listed instructions could place the
individual at risk of serious injury or death.
The statements used with this level of
warning deal with a safe operating
procedure. If the procedure is ignored, the
possibility of personal injury may exist.
FIGURE 1 - LOCKOUT/TAGOUT

INSTALLATION INSTRUCTIONS
(No Hydraulic Leveler Present in Pit)
1. Install VBR6 insert (if removed during pit work) and
tighten (6 ea.) nylock nuts on back face and (2 ea.)
jam nuts on base. See figure 2
2. Install hydraulic dock leveler per dock leveler
installation instructions.
3. Manually raise and strut dock leveler.
HYDRAULIC CYLINDER SUPPORT
(Dock Leveler)
4. If the base clevis of the hydraulic cylinder on the
dock leveler is over the opening of the Dok-Lok,
cylinder support must be placed centered on
cylinder clevis and shimmed to support hydraulic
dock leveler. See figure 3.
5. If the base clevis of the hydraulic cylinder on the
dock leveler is not over the opening of the Dok-Lok,
cylinder clevis needs to be shimmed to pit floor to
support hydraulic dock leveler.
6. Route Dok-Lok hydraulic hoses thru the back
opening of the Dok-Lok pit. See figure 4.

7. Mount a waterproof junction box and stand alone
power unit, if equipped, to the pit floor near Dok-Lok
pit. See figure 4 & 5.
8. Route and secure (SW2) stored sensor cable with
the Dok-Lok hydraulic hoses. Terminate into junction
box. See figure 4.
9. Route and secure (SW1) R.I.G. sensor cable
leaving a minimum loop of 20”. Secure with stored
switch and hoses. Terminate into junction box.
Ensure that the switch cable has enough slack to
travel with the barrier through the entire locking
range. See figure 4.

INSTALLATION PROCEDURES.
11. Install the control box on a wall adjacent to the
overhead door at approximately 48" above the floor
level. See Figure 6.
12. Drill a hole for the power supply conduit (by others) in
the bottom of the control box. All holes drilled
through the control box must be through the

INSTALLATION CONT.
• When drilling holes in the box, DO NOT allow
the drill to go too deeply into the box.
Damage to the control systems may occur.
• DO NOT turn control box upside down to drill
any access holes. Cover internal electrical
components prior to drilling - this will prevent
debris from contacting the internal electrical
components.
• Remove all debris from box using a shop
vacuum. NEVER use air to blow debris from
the control box.

INSTALLATION CONT.
Control Box Installation Guidelines -
Temperature Controlled Applications.
a. Conduit should be routed to enter through the
bottom or side of the enclosure. A drip leg may
be needed if the conduit could fill with water.
b. Seal the conduit in any location where the
conduit transitions temperature zones that may
produce condensation.
c. Spacers should be installed between the
enclosure and the wall to provide tempature
insulation and air flow.
13. Connect wiring as indicated by the Electrical
Schematic and Wiring Diagram. See figures 7 & 8
or figures 9 & 10.
14. To complete installation see page 12, Fill and Bleed
Hydraulic System section.
• The control box and all wiring should be
installed by a qualified electrician in
accordance with all national and local
electrical codes.
• If rigid conduit is installed, bonding must be
maintained between conduit connections by
using ground bushings and a jumper wire.
