SAFETY PRACTICES
Read and follow all safety practices, placards
and owners manual warnings before installing,
operating or servicing the Dockleveler. Failure
to follow the information provided could result
in death or serious injury.
Before doing any maintenance or repair on the
dock leveler SECURE WITH THE MAINTENANCE
STRUT. See Fig. 23 & 24.
If you do not understand the instructions or if you
have any proble s or questions using or operating
the dock leveler, contact your supervisor or the
factory for assistance.
OPERATION
ONLY trained ersonnel are to o erate or service
dockleveler. Follow rocedure on lacards osted
near dock leveler. Call factory for re lacement
lacards, warning labels, or owner’s manual.
ALWAYS before activating dock leveler:
- Ensure trailer is backed in against
bum ers.
- Remove any end loads if required.
- Check trailer alignment to avoid li
interference. If li does not lower
to trailer bed, re osition
vehicle.
- Chock truck wheels or lock truck in
lace with a truck restraining
device and set brakes.
ALWAYS before allowing vehicle to leave the dock:
- Ensure that no equi ment, material
or eo le are on the dock leveler.
- Return the dock leveler to its stored
osition at dock level.
NEVER exceed 5 m h when driving on leveler.
NEVER exceed the rated ca acity of the leveler.
NEVER travel on leveler unless li is securely on
truck floor. Visually check that the li is su orted
by the truck bed and has a minimum of 4” of
overla onto the truck bed.
NEVER travel on the bum er blocks or over the
edges of the leveler.
DO NOT o erate the dockleveler with equi ment,
material, or eo le on or in the ath of the ram or
li .
DO NOT o erate the dockleveler when anyone is in
front of it.
DO NOT attem t to lift or lower the dockleveler
ram or li by any means other than that described
in the o eration rocedures contained in this
manual. Kee hands and feet clear of the hinges at
all times and maintain a safe distance from the
underside of the leveler while raising or lowering.
NEVER stand in the driveway between the
dockleveler and a backing truck.
DO NOT use this unit to service trailers outside its
intended working range, which is 5” above and 5”
below dock height. Verify with the manufacturers of
all equi ment to be used on your s ecific edge-of-
dock leveler, to ensure that o erating equi ment at
all s ecified grades are within safe o eration. Do
not o erate any equi ment that will not safely
o erate at any of the grades shown on age 4 at
either ram or li .
Many trailers have air ride sus ensions that may
cause the trailer to move away from the dock
during loading and unloading o erations (commonly
referred to as dock or trailer walk). The otential for
dock walk caused by air ride sus ensions may be
reduced by exhausting or “dum ing” the air from the
air ride sus ension system before servicing the trail-
er.
DO NOT USE THE DOCKLEVELER if it looks
broken or does not seem to o erate ro erly. Tell
your su ervisor it needs re air right away.
DO NOT o erate the dockleveler if o eration causes
undue hysical strain or if hysical im airments
could lead to undue strain in back, muscles, limbs,
or joints.
ALWAYS kee both hands firmly on the hand
leveler while raising or lowering the dockleveler.
Kee other body arts clear of hand lever travel
ath while raising or lowering the dockleveler.

CALCULATIN CAPACITY
Determining required leveler ca acity: Determine
gross vehicle weight (GVW = lift truck weight +
battery + heaviest load) of the largest lift truck to be
used. The (GVW x 1.5) = the minimum leveler
ca acity for normal use. However, if any one of the
following condition below exists, multi ly the (GVW
x 2.1) to determine the minimum leveler ca acity. If
two or more of these conditions exists multi ly the
(GVW x 2.55). If a three-wheeled fork truck is to be
used a 30,000# ca acity Edge of Dock is
recommended, unless the GVW multi lied by the
factors requires a higher ca acity. (Refer to Figure
2 for reference)
CONDITIONS
More than 8 trucks serviced per day
Three-Wheeled fork trucks (14,000# GVW or less)
Fork trucks travel faster than 3-ph
Fork trucks have front-end attach ents or side
shifters
Do not exceed dockleveler capacity. Over
loading dockleveler could result in death or
serious injury.

GENERAL INSTALLATION
Read and follow Safety Practices on page 2.
Failure to follow these safety practices could
result in property damage, serious injury or
death.
Installation should not be attempted by persons
not familiar with equipment and techniques
required for proper installation. Improper
installation could result in property damage,
serious injury or death.
1. Using a 1,000# minimum ca acity late clam ,
clam the li late at the center of the width.
(See Figure 12).
Inadequate lifting equipment or practices can
cause a load to fall unexpectedly. Make sure the
lifting chain or other lifting devices are in good
condition and have a rated capacity of at least
1000 lbs. for the lifting angle used. Never allow
anyone to stand on or near the dockleveler
when it is lifted or placed onto the dock. Stand
clear of the dockleveler when it is being placed
onto the dock. Failure to follow this warning can
allow the dockleveler to fall, tip, or swing into
people, causing death or serious injury.
Follow plate clamp manufacturer’s use
instructions. Failure to follow plate clamp
manufacturer’s use instructions could result in
property damage, death or serious injury.
2. Position dockleveler mounting late centered on
face of dock and 1/4” below to of curb channel,
transition late, angle late or steel a roach
ram . (See Figure 12).
NOTICE!
The dockleveler ust be plu b to operate properly.
Use shi s or re ove concrete as necessary to
ake the ounting plate plu b.
3. Weld two 2” welds at the u er outside edges of
the mounting late and lug weld the two outer
holes in the mounting late (if curb channel is
not used install two 5/8” DIA. anchors).
4. Su ort dockleveler by inserting hand lever into
lever socket located on right side of ram late.
(See Figure 17).
5. While one erson holds the hand lever down as
shown in (Figure 18), with the use of the late
clam , carefully lower li to the full back osition
as shown in (Figure 18). Remove late clam .
6. Using the hand lever, carefully lower the
dockleveler to the rest osition as shown in
(Figure 22). While lowering dockleveler to the
rest osition it is necessary to have another
erson use a i e or similar device to hold the
li extender link disengaged as shown in (Figure
18). This will revent the li from extending out
away from the dock.
Do not use hands or feet to hold lip extender link
disengaged. Use of hands or feet could cause a
pinch point resulting in death or serious injury.
Failure to keep lip extender link disengaged
while lowering dockleveler could result in
damage to the link.
7. Weld four 1” long welds evenly s aced across
the to edge of mounting late to secure
dockleveler.
8. With the hand lever, hinge the ram to the
u right osition and back to rest osition,
checking for freeness to ram and mounting
late hinge.
Do not allow lip and ramp to fall free. Allowing
the dockleveler to fall free could result in the
dockleveler coming free from the dock or
damaging linkage, resulting in property damage,
serious injury and/or death.
Do not allow lip to extend out away from the
dock before all welding and anchor installation
is complete. Operating the dockleveler before
all installation is complete could result in
property damage, death or serious injury.

7. With the dockleveler in the rest osition, adjust
the hydraulic cylinder rod eye so that the rod eye
hole center is about 3-1/2” from the unthreaded
ortion of the extension rod. Then extend the
hydraulic cylinder until the rod eye lines u with
the hole in the u er mounting bracket. Verify
that the EOD ram late is resting on the
mounting late gussets. (See Figure 15).
Do not use fingers to check alignment, use bolt
supplied. A pinch point could result in serious
injury.
If electrical connections are completed prior to
hydraulic cylinder adjustment, disconnect and
lockout until all work is done. Failure to follow
these safety practices could result in death or
serious injury.
The “L” dimension (or minimum amount of
exposed extension rod with the dockleveler in
it’s rest position.) must be greater than 1-3/4”.
Failure to do so will cause the hydraulic cylinder
to bottom out under load resulting in permanent
damage to the hydraulic cylinder.
8. Assemble and tighten 5/8” hex bolt and lock nut
su lied. Then tighten the rod eye nut to secure
rod eye. (See Figure 15).
9. Mount control box er local codes. Control box
should be mounted inside the building, and give
the o erator a clear view of the dock during use.
The control box must be mounted where the
o erator has a com lete and clear view of the dock
and EOD during o eration. Failure to mount the
Control Box in the correct area could result in
ersonal injury or death.

OPERATION
Before operating the dockleveler, read and
follow Safety Practices on pages 5 & 6.
Use by untrained people could result in serious
injury or death. Read and follow complete
Operation instructions. DO NOT USE THE
DOCKLEVELER IF IT LOOKS BROKEN OR DOES
NOT SEEM TO WORK RI HT. Tell your
supervisor it needs repair.
Always be certain that the truck wheels are
chocked, or that the truck is locked in place by a
truck restraining device and the brakes are set,
before loading or unloading. Trucks pulling
away from the dock unexpectedly could result in
death or serious injury.
Keep both hands firmly on the hand lever while
raising or lowering the dockleveler. Keep other
body parts clear of hand lever travel path while
raising or lowering the dockleveler. Do not use
legs or feet to move or hold hand lever. Failure
to follow these and other provided warnings
could result in death or serious injury.
Do not operate dockleveler if operation causes
undue physical strain or if physical impairments
could lead to undue strain in back, muscles,
limbs, or joints.
To avoid damage to load and dockleveler do not
activate unit if loads will be in way of extended
lip. If the lip touches loads before resting on
carrier floor, linkage must be disengaged. Use
hand lever to hold 12” ramp plate in the full back
position and with a pipe or similar device,
disengage lip extender link from the extender
bushing. Once disengaged, return unit to rest or
pendant position.
INTRODUCTION
The Edge-of-Dock Dockleveler is designed to s an
and com ensate for s ace and height differences
between a loading dock and freight carrier to allow
safe, efficient freight transfers.
The Mechanical Edge-of-Dock Dockleveler is s ring
counterbalanced. A hand lever is used to osition
the ram and li onto the truck bed and to return the
dockleveler to the stored osition.
Moving the hand lever back moves the ram to the
full raised osition, engaging the li extension link.
Moving the lever forward extends the dockleveler li
onto the truck.
After loading, moving the hand lever moves the li
off the truck. The hand lever is then moved back to
lace the dockleveler back into stored osition.
1. Wait until a truck is in osition against the dock
bum ers.
2. Tell truck driver “ Your truck must stay at the
dock.”
3. Chock or hitch truck.
4. Remove end loads with the dockleveler in the
stored osition. (See Figure 16).
FIGURE 16
5. To extend the dockleveler li into the truck:
5.1 Insert hand lever into lever socket
located on right side of ram late.
(See Figure 17).
