Caster System
Standard on the PR 4500 Series
are shim free, spring loaded,
articulating, stabilizing casters for
fork lengths up to 96". Quick
adjustment casters with torsion
bar are standard on fork lengths
above 96". Quick adjustment

Operator Area and Controls
The PR 4500 Series incorporates
numerous design features to
improve operator comfort and
productivity. The side-stance
position provides the operator
with maximum visibility. The
compartment cradles the operator
with a wrap-around chassis while
the suspended floorboard with
premium floor mat provides
maximum comfort.
7. Polyurethane load wheels
Quick adjustment casters adjust
quickly to enable braking, traction,
steer effort and stability to become
balanced. This system can also
increase tire life by as much as
60 percent by permitting more
tire wear. The torsion bar suspen-
sion is designed to maximize
stability on tall unwieldy and less
stable loads.

sion bar (fork length > 96")

Technical Information
PR 4500 Series
Fork adjustability is done at the
toe with no need to remove a
cover plate. Fork heel height ad-
justment is done quickly without
removing battery. Quick and
easy fork adjustment promotes
servicing of fork assembly to
keep pallet entry/exit productive.
Pallet Planning Guide
Other Options
Fork Assembly
On standard-tip fork models, the
load wheel will drop in the second
opening of the pallet when “A” or
“B” dimension equals the nominal
fork length. On extended-tip fork
models, the load wheel will drop
in the first opening of the second
pallet. On models with a single
load wheel, the “C” dimension
should be 6" maximum and the
“D” dimension should be 14"
minimum. On models with tandem
load wheels, the “C” dimension
should be 6" maximum and the
“D” dimension should be 17"
minimum. Customers that need
tandem load wheel trucks, but
use pallets with smaller openings,
may be accommodated if the
maximum lift height of the truck
is reduced. Contact your local
Crown dealer for details.
1. Audible travel alarm
Fork width - 9.12" on standard-tip
fork models, 10" on extended-tip
fork models. Fork spread - 22"
and 27" on standard-tip models.
23" - 26" spread available in one
inch increments. 23" and 28"
standard on extended-tip models.
Fork spreads from 24"-27" avail-
able in one-inch increments.
Fork lengths - 36", 42", 48", 54",
60", 96" with standard-tip; 84",
93", and 96" forks available with
extended-tip design for shorter
wheelbase.
2. Flashing lights
Safety considerations and
dangers associated with audible
travel alarms and flashing lights
include:
•
Multiple alarms and/or lights
can cause confusion.
Pull rod design incorporates
a replaceable “tenon” for fast
servicing of pull rod while still in
the truck. Damage related to
impacts is limited to the replaceable
“tenon”, not the entire pull rod.
•
Workers may ignore the
alarms and/or lights after
day-in and day-out exposure.
•
•
Operator may transfer the
responsibility for “looking out”
to the pedestrians.
Power Unit Structure
Heavy gage steel is used in the
platform and power unit skirt with
additional steel reinforcement
where needed.
To facilitate pallet entry/exit
Crown has engineered several
features into their fork assembly.
Standard-tip forks have pallet
entry rollers to lift fork over
bottom board of pallet. Rollers
are made of high molecular
weight polyethylene with .75"
axle and roll pin.
Annoys operators and
pedestrians.
Dimensions and performance
data given may vary due to
manufacturing tolerances.
Performance is based on an
average size vehicle and is
affected by weight, condition of
truck, how it is equipped and
the conditions of the operating
area. Crown products and
specifications are subject to
change without notice.
The power unit door and motor
cover also utilize heavy steel for
protection of critical components
and long term durability. The
power unit door swings out for
easy access to components.
B
Extended-tip fork design has
totally enclosed tip with full length
convex bottom surface creating
an entry ramp. Ramp design
helps fork glide over bottom
boards of pallet and keeps welded
edges from touching boards
of pallet.
A
e-GEN™ Braking System
Variable regenerative motor
braking is optimized and virtually
eliminates brake maintenance.
When the truck is traveling, if
the operator releases the brake
pedal, removes travel input
request or reverses direction
e-GEN braking is applied.

Abrasion resistant steel entry/exit

from contact point of slide.
