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

casters with torsion bar is optional  
for 96" forks and below.

and other system inputs and  
outputs. Access 1 2 3 technology  
simplifies the system by reducing  
componentry including contactors,  
relays, and other hard-wired  
components.

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.

free casters (fork length < 96")  
9. Quick-adjust caster with torr-

InfoPoint System allows your  
technician to troubleshoot without  
complicated schematics, wiring  
diagrams or cumbersome service  
manuals for over 95% of your  
repairs. Simplicity is complete  
with InfoPoint Quick Reference

maps, and “information nuggets”  
located on the truck.

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

which have convex bottom  
surfaces to prevent snagging as

radial edges are welded away  
from contact point of slide.
