A DOK-LOK vehicle restraint may be installed on docks
with or without levelers. Consult RITE-HITE for proper
application.
Follow the six (6) step installation procedure below:
1. Inspect DOK-LOK materials.
2. Anchor or Weld track.
3. Position DOK-LOK assembly into track.
4. Electrical component and sign installation.
5. Hydraulic installation.
6. Test operation.
INSPECT DOK-LOK MATERIALS
Open and inspect all materials. Immediately report any
damage or material shortage. Study component
assemblies and determine their proper locations.
Install DOK-LOK vehicle restraint onto dock face at 27
inches off of the approach, unless otherwise noted in the
“RITE-HITE Installation/Application Guidelines”, at the
specified location by welding to an embedded steel plate
or by using the concrete anchors provided in conjunction
with welding to pit steel and a leveler frame. The track
will need to be trimmed if the mounting height is less than
26 inches. A maximum of 1 inch is allowed between the
bottom of the track and the approach.
For site specific installation refer to RITE-HITE
Installation/Application information provided with DOK-
LOK vehicle restraint. If the recommended mounting
height cannot be achieved call your RITE-HITE
Representative or RITE-HITE Customer Service at (800)
456-0600.
NOTES
:
a. Some levelers may be slightly recessed or protruding
within pit. A shim must be inserted between the roller
track plate and the leveler front subframe and then
must be welded in place. See page 17.
b. If the dock conditions DO NOT allow lights and signs
to be mounted in full view of the forklift and/or truck
trailed drivers, consult the factory.
c. If the DOK-LOK is installed with a hydraulic leveler,
verify that the leveler’s recycle function has not been
adversely affected.
d. Track MUST be centered. Offset track installations
ARE NOT allowed. If there is existing anchor hole
interference call your RITE-HITE Representative or
RITE-HITE Customer Service at (800) 456-0600.
e. Approach must be concrete or there must be a
concrete pad where the base plate is installed.

INSTALLATION
When lifting carriage use a proper lifting device
(ex. crane, jack). Lifting by hand may cause back
injury.
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.
Whether there is a leveler or not, a 4" thick
bumper is required. DO NOT install a
DOK-LOK
vehicle restraint on docks without 4" thick
bumpers. For thicker bumpers consult factory.
