NOTICE TO USER
Definition and Function

The STR-4200 Dok-Lok vehicle restraint is a hydraulic,

self-aligning restraint device used to secure trucks and

semi-trailers with an intact Rear Impact Guard (RIG) to

the face of a loading dock In addition this device, when

engaged, limits the vertical motion of the trailer when

loading and/or unloading This is achieved by securing

the RIG with a hydraulically positioned steel hook, while

support cylinders extend under the carriage to limit vertical

motion 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 flashing green or red lights located at the inside

of the building for the forklift operator, 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

the forklift operator if there is not RIG present, or if

the engagement is improper In this case, the trailer

must be secured by other means (wheel chokes, etc)

prior to servicing trailer

Prerequisite for proper barrier engagement is that the

trailer is parked firmly against a 4in [102mm] (trade

standard) thick dock bumper The activation/deactivation is

solely controlled from inside of the building by pressing the

Lock (raise) button or the Unlock (lower) button

The normal mode of the hook is in the lower STORED

position, with support cylinders retracted 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 depress

the Lock button This will raise the hook to engage the

RIG and simultaneously extend the support cylinders

to support the carriage As soon as the RIG is

properly locked with carriage supported, there will be a

simultaneous light change - the inside will change from red

to green flashing (trailer secured and supported) and the

outside will change from green to red flashing (

DO NOT

move trailer) After the service is complete, the dock

attendant will have to depress the Unlock button which

then will return the hook and support cylinders to their

STORED position
A proper hook engagement is achieved when the hook

raises unobstructed to fully trap the horizontal cross

member of the RIG Assembly An improper hook

engagement is if the horizontal cross member of the

RIG is missing, obstructed or it is bent or located too

far from rear of trailer that it will prevent the free passage

of the hook At this point, the trailer must be secured by

other means (example: wheel chocks) in order to become

serviceable

CAUTION

The support cylinders will not be engaged without

proper hook engagement. If trailer can not be

secured, expect normal vertical motion of the trailer.
