RHV Dock Leveler Owner’s Manual

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 specifications for replaceable or
repairable parts

Tables identifying the grade (slope) for all 
variations of length or configuration of the dock
equipment

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.

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.

10.

In selecting dock equipment, it is important to  
consider not only present requirements but also
future plans or adverse environments.
