DEFINITION AND FUNCTION FEATURES
The VBR-300ALP DOK-LOK vehicle restraint is a manually
activated, ground stored restraint device used to secure trucks
and semi-trailers 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 steel barrier positioned by a gas spring 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 or improper activation of the barrier is monitored by:
• VISUAL CONTROL
— One set of flashing green or red lights located at the
inside of the building for the forklift operator, and one
set located outside of the building for the truck driver In
addition to the lights, there are three instruction signs
• AUDIO CONTROL
— A horn will sound at the inside of the building, warning
the forklift operator if there is no 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 firmly against a 4” (trade standard) thick dock bumper.
The activation/deactivation is solely controlled from the inside of
the building by momentarily depressing either the Lock (raise)
button or the Unlock (lower) button.
The normal mode of the barrier is in the lower STORED
position, showing a flashing red light (trailer not secured) at the
inside of the building and a flashing 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 lift the barrier
with the operating bar This will raise the barrier to engage the
R I G As soon as the R I G is properly locked, there will be
simultaneous light change — the inside will change from red to
green flashing (trailer secured) and the outside will change from
green to red flashing (do not move trailer). After the service is
completed, the dock attendant will have to lower the barrier with
the operating bar to its stored position and press the UNLOCK
button to change the lights 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 toward
the rear axle of the trailer that it will prevent the free passage of
the barrier In either case, the lights will stay in a non-serviceable
mode and a horn will sound At this point, the trailer must be
secured by other means (example: wheel chocks) in order to
become serviceable

R.I.G.
Acronym used for the Federally mandated rear impact guard
located on the rear of over the road trailers to prevent accidental
underride by automobiles
ROLLER TRACK ASSEMBLY
Mounted to the loading dock wall to guide the barrier assembly
in a vertical plane and transmit the creep or pull out force from a
trailer to the loading dock wall
BARRIER ROLLER ASSEMBLY
Comprised of a steel roller housing, a pre-lubricated needle
bearing to allow easy movement of the barrier assembly
GAS SPRING
Keeps barrier assembly in constant contact with the R I G
R.I.G. SENSOR
Detects when the barrier is secured to the R I G
BARRIER ASSEMBLY
Secures R.I.G. to prevent trailer from rolling/creeping away from
the dock
BASE COVER
Protects the barrier assembly, float mechanism, hydraulic hoses
and lift cylinder from debris
TRACK COVER WITH INTEGRAL LIP GUIDE
Keeps debris out of the roller track Integral lip guide is used to
guide the lip past the roller track assembly in a below dock end
load condition
CONTROL BOX, OUTSIDE LIGHT BOX AND SIGNAGE
Combination of these components is used to provide audio/visual
communications to the dock attendant and trailer driver
OPERATING BAR AND BRACKET
Used to position the barrier assembly from inside of building
Bracket provides storage for Operating Bar while not in use
