NOTICE TO USER
Owner Responsibility
1. The owner should recognize the inherent danger of
the interface between dock and transport vehicle. The
owner should, therefore, train and instruct operators in
the safe use of dock equipment in accordance with the
information provided below. The manufacturer shall
publish, provide to the initial purchaser, and make the
following information readily available to owners:
• Installation instructions
• Recommended initial and periodic inspections
procedures
• Maintenance procedures
• Operating instructions
• Descriptions or specications for replaceable or
repairable parts
• Tables identifying the grade (slope) for all variations
of length or conguration of the dock equipment, and
• Information identifying the maximum uncontrolled
drop encountered upon sudden removal of support
while within the working range of the equipment.
It shall be the responsibility of the owner to verify that
the material listed in this section has been received
and that it is made available for the instruction
and training of personnel entrusted with the use or
maintenance of the dock equipment.
2. When a transport vehicle is parked at a loading
dock, it is important that the vehicle is relatively
perpendicular to the dock face and in close contact
with at least one of the dock bumpers.
3. Nameplates, cautions, instructions, and posted
warnings shall not be obscured from the view of
operating or maintenance personnel for whom such
warnings are intended.
4. Manufacturer’s recommended periodic maintenance
and inspection procedures in effect at date of
shipment shall be followed, and written records of the
performance of these procedures should be kept.
5. As with any piece of machinery, dock equipment
requires routine maintenance, lubrication, and
adjustments. Your local Rite-Hite representative offers
owners the option of a Planned Maintenance Program
(P.M.P.). As part of this service, your local Rite-Hite
representative will do all routine maintenance,
lubrication, and adjustments.
6. Dock equipment that is structurally damaged shall be
removed from service, inspected by a manufacturer’s
authorized representative, and repaired as needed
before being placed back in service.
7. The manufacturer shall make available replacement
nameplates, caution/instruction labels, and operating/
maintenance manuals upon request of the owner.
The owner shall see that all nameplates, caution/
instruction markings or labels are in place and legible,
and that the appropriate operating/maintenance
manuals are provided to users.
8. Modifications or alterations of dock equipment shall
be made only with written permission of the original
manufacturer. These changes shall also satisfy all
safety recommendations of the original equipment
manufacturer for the particular application of the dock
equipment.
9. In order to be entitled to the benefits of the standard
product warranty, the dock equipment must have
been properly installed, maintained and operated
within its rated capacities and/or specific design
parameters, and not otherwise abused.
10. It is recommended that trailers equipped with air
ride suspensions should remove the air from the
suspension to minimize trailer bed drop, prior to
loading or unloading.
11. When industrial trucks are driven on and off transport
vehicles during the loading and unloading operation,
the brakes on the transport vehicle shall be applied
and wheel chocks or a positive restraining device
shall be engaged.
12. It is recommended that an adequate stabilizing device
or devices be employed at the front of the trailer in all
cases where a trailer is being loaded or unloaded with
the trailer resting on its support legs (landing gear)
rather than a tractor fifth wheel or a converter dolly.
13. In selecting dock equipment, it is important to consider
not only present requirements but also future plans or
adverse environments.

VBR‑300 Dok‑Lok®Owner’s Manual Rite‑Hite®

NOTICE TO USER
Definition and Function
The VBR-300 Dok-Lok vehicle restraint is a hydraulic,
ground stored restraint device used to secure trucks and
semitrailers with an intact Rear Impact Guard (R.I.G.) to
the face of a loading dock. This is achieved by securing
the R.I.G. with a hydraulically powered steel barrier. This
prevents forward movement of the truck/trailer that may
create an unsafe void between the face of the dock and
the rear end of the truck/ trailer as a forklift travels from the
loading dock onto the trailer; or to create an obstruction
noticeable to the truck driver, should the driver accidentally
try to pull the truck/trailer away while it is being serviced.
The proper activation of the barrier and the locking
mechanism is monitored by:
• Visual Control
1 set of ashing green or red lights located at the inside
of the building for dock personnel and 1 set located
outside of the building for the truck driver. In addition to
the lights, there are 3 instruction signs.
• Audio Control
A horn will sound at the inside of the building, warning
dock personnel if there is not R.I.G. present, or if the
engagement is improper. In this case, the trailer must
be secured by other means (wheel chocks, etc.) prior
to servicing trailer.
Prerequisite for proper barrier engagement is that the
trailer is parked rmly against a 4in [102mm] (trade
standard) thick dock bumper. The activation/deactivation is
solely controlled from inside of the building by momentarily
pressing either the Lock (raise) button or the Unlock
(lower) button.
The normal mode of the barrier is in the lower STORED
position, showing a ashing red light (trailer not secured)
at the inside of the building and a ashing green light
(trailer free to move to or away from the loading dock) at
the outside of the building.
Once the trailer is parked, the dock attendant will depress
the Lock button. This will raise the barrier to engage the
R.I.G. As soon as the R.I.G. is properly locked, there will be
a simultaneous light change - the inside will change from
red to green ashing (trailer secured and supported) and
the outside will change from green to red ashing (DO NOT
move trailer). After the service is complete, the dock
attendant will have to depress the Unlock button which then
will return the barrier to its lower STORED position.
A proper barrier engagement is achieved when the
barrier raises unobstructed to secure the horizontal cross
member of the R.I.G. Assembly. An improper barrier
engagement is if the horizontal cross member of the
R.I.G. is missing, obstructed or it is bent or located so far
from rear of trailer that it will prevent the free passage of
the barrier. At this point, the trailer must be secured by
other means (example: wheel chocks) in order to become
serviceable.
