Operator Area and Controls  
The PC 4500 Series incorporates  
an operator compartment designed  
for comfort and productivity.  
System Control with AC  
Traction  
This system provides unmatched  
truck control and system perfor-  
mance in:  
The compartment features  
rounded edges, a large operator  
platform to allow quick entry/exit  
onto the truck and a choice of  
handle options. Dual twist grips  
with soft urethane covering and  
cams improve operator comfort.  
Full width raise, lower and horn  
buttons are employed for easy  
actuation.  
* Traction control  
* Operator interface  
* Diagnostics  
Clearly labeling each component  
and providing an area map  
showing component locations  
helps to minimize downtime.  
A Quick Reference Trouble-  
shooting Guide is supplied with  
each truck showing display  
operation, code definitions,  
and overall component ID of  
the entire truck.

Crown technology provides  
a closed-loop traction control  
system which maintains speed  
throughout the battery charge  
and provides optimum accelera-  
tion and speed as the load on  
the forks increases.  
Optional Equipment  
1. “T”-type control handle  
includes urethane covered  
twist grips with cams, full  
width raise, lower and horn  
buttons with automatic park  
brake  
2. Molded urethane leg cushion

In low level order picking applica-  
tions, where walking through the  
compartment is common, the  
larger compartment, low profile  
high speed pedal, rounded edges  
and optional load backrest widths  
and heights improve order picking  
efficiency. Preset lift height pro-  
vides operators with a consistent  
platform step height and is ad-  
justable to individual operator  
preference for improved comfort  
and productivity.  
Access controller has full-time  
management control of traction  
and other system inputs and  
outputs. Access 123 technology  
simplifies the system by reducing  
componentry including contac-  
tors, relays and other hard-wired  
components. The Access 123  
system is covered by a 3 year /  
6000 hour supplemental warranty.

Technical Information  
PC 4500 Series  
Hydraulics  
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 bottom  
boards of pallet.  
e-GEN Braking System  
Heavy-duty pump, motor, reservoir  
and control are assembled into  
one unit. A centrally located lift  
cylinder, mounted vertically,  
is equipped with long-life  
Variable regenerative motor  
braking is optimized and virtually  
eliminates brake maintenance.  
Other Options  
1. Audible travel alarm  
2. Flashing lights  
While moving, e-GEN braking is  
applied if the operator moves the  
standard handle into the brake  
zone, activates brake levers on  
“T” handle, removes travel input  
request or reverses direction.  
Safety considerations and dangers  
associated with audible travel  
alarms and flashing lights include:  
polyurethane packings. A  
pressure compensating flow  
control valve is an integral part  
of the valve block and regulates  
lowering speed. Overload valve  
protects hydraulic components.  
Abrasion resistant steel entry/exit  
slides on both sides of each fork  
have convex bottom surfaces to  
prevent snagging as forks move  
over bottom boards of pallet.  
One-piece design with radiused  
edges are welded away from  
contact point of slide.  
• Multiple alarms and/or lights  
can cause confusion.  
• Workers ignore the alarms  
and/or lights after day-in and  
day-out exposure.  
The closed loop Access 123  
traction control will keep the  
truck static until a travel input is  
requested, even when operating  
on a grade.  
Drive Unit  
All gear drive from drive motor to  
drive wheel axle. Crown-manu-  
factured gears are hard finished  
and dual machined for high quality.  
Drive tire axle is mounted in the  
drive unit on both sides for maxi-  
mum strength in rough floor or  
docking applications. Drive unit is  
top and bottom mounted. Top  
mount is a large, tapered roller  
bearing for vertical or horizontal  
forces. Bottom mount has four  
shock mounted rollers on drive  
unit running in a hardened steel  
roller race. Gear train runs in oil-  
filled, sealed housing.  
• Operator may transfer the  
responsibility for “looking out”  
to the pedestrians.  
Automatic electric parking brake  
activates when the truck has  
been stationary for four seconds,  
the truck is keyed off or the bat-  
tery has been disconnected.  
Exit roller design prevents load  
wheel from dropping after cross-  
ing bottom board. The 4" wide,  
steel exit roller is positioned di-  
rectly behind the load wheel  
to keep the fork rolling. The  
• Annoys operators and  
pedestrians.  
Dimensions and performance  
data given may vary due to manu-  
facturing tolerances. Performance  
is based on an average size vehicle  
and is affected by weight, condi-  
tion of truck, how it is equipped  
and the conditions of the operating  
area. Crown products and speci-  
fications are subject to change  
without notice.  
.
entry/exit slide design also assists  
in trouble-free pallet entry/exit.  
Pallet Planning Guide  
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" mini-  
mum. 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 Crown  
dealer for details.  
Fork adjustment is done at the toe  
with no need to remove a cover  
plate. Fork heel height adjustment  
is done quickly without removing  
battery. Quick and easy fork  
adjustment promotes servicing of  
fork assembly to keep pallet  
entry/exit productive.  
Caster System  
Standard on the PC 4500 Series  
are the quick adjustment casters.  
These casters adjust quickly to  
enable braking, traction, steer  
effort and stability to be  
Pull rod design incorporates a  
replaceable “tenon” design for

“balanced” based on your  
specific application. This system  
can also increase drive tire life by  
as much as 60% by permitting  
more tire wear. The optional  
torsion bar suspension is avail-  
able to maximize stability on tall,  
unwieldy and less stable loads.  
Power Unit Structure  
Heavy gage steel is used in the  
power unit structure and skirt.  
Rugged steel power unit doors  
protects electronic components  
and swing open providing

excellent access. Doors also can  
be lifted off if desired. Door bolts  
have exclusive convex design  
that mate with concave door  
holes for fast reinstallation of bolts.

on the Power Unit and Fork  
Weldment structures.
