Operator Area and Controls
The PC 4500 Series incorporates
an operator compartment designed
for comfort and productivity.
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.
In low level order picking applications, 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 provides operators with a consistent
platform step height and is adjustable to individual operator
preference for improved comfort
and productivity.
PC 4500 Series
Technical Information
When the high speed pedal is
engaged, it is approximately flush
with the platform cushion for
maximum comfort.
A large back cushion and molded urethane platform cushion are
standard to minimize fatigue
when the operator is in transport
position.
Optional leg cushions are available to further reduce fatigue,
increase comfort and maximize
productivity.
Optional width and height load
backrests can be specified for
your application. Hip, shoulder and
elbow clearance are maximized
when this feature is customized
to your operators and load sizes.
An optional control module is
available to provide raise, lower
and horn buttons in the load
backrest.
Electrical System
Heavy-duty 24-volt electrical
system for demanding warehouse, dock and transport applications. Crown-manufactured
AC drive motor delivers powerful
performance and proven reliability
for long lasting productivity in
any environment.
A lift limit switch shuts the pump
motor off at full fork elevation.
Color coded wiring is used for
ease of service.
Access 123® Comprehensive
System Control with AC
Traction
This system provides unmatched
truck control and system performance in:
* Traction control
* Operator interface
* Diagnostics
Crown technology provides
a closed-loop traction control
system which maintains speed
throughout the battery charge
and provides optimum acceleration and speed as the load on
the forks increases.
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 contactors, relays and other hard-wired
components. The Access 123
system is covered by a 3 year /
6000 hour supplemental warrantyy.
The Access ™ display offers six
hour meter readouts and
odometer. The operator message
mode can be programmed to
display model number (default),
BDI, truck hours, odometer, trip
odometer or timer. Built-in PINcode (up to 25) capability.
The Access display also includes
a full featured on-board service
tool. Proven Access 123
diagnostics has been extensively
developed to provide superior
troubleshooting and service
ease. The service technician can
actively view inputs and outputs
during truck operation. Event
code history includes the most
recent event code plus the previous 15 codes. No service key,
laptop or handset required.
Performance tuning is accessed
through the display to customize
truck performance for specific
applications or operator
requirements.
The large Crown-manufactured
AC drive motor specifically designed for lift truck applications,
provides improved acceleration
and plug reversal contributing to
greater productivity.
InfoPoint®
InfoPoint System allows technicians to troubleshoot without
complicated schematics, wiring
diagrams or cumbersome
service manuals for over 95%
of repairs. Simplicity is complete
with InfoPoint Quick Reference
Guide, color-coded components
maps and “information nuggets”
located on the truck.
Clearly labeling each component
and providing an area map
showing component locations
helps to minimize downtime.
A Quick Reference Troubleshooting Guide is supplied with
each truck showing display
operation, code definitions,
and overall component ID of
the entire truck.
PC 4500 Series
Hydraulics
Heavy-duty pump, motor, reservoir
and control are assembled into
one unit. A centrally located lift
cylinder, mounted vertically,
is equipped with long-life
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.
Drive Unit
All gear drive from drive motor to
drive wheel axle. Crown-manufactured gears are hard finished
and dual machined for high quality.
Drive tire axle is mounted in the
drive unit on both sides for maximum 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 oilfilled, sealed housing.
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
“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 available to maximize stability on tall,
unwieldy and less stable loads.
Fork Assembly
Fork width - 9.12" on standardtip fork models, 10" on extendedtip fork models. Fork spread - 22"
and 27" standard on standard-tip
models. 23"- 26" spread available
in one-inch increments. 23" and
28" standard on models with
extended-tip models. Fork spreads
from 24"- 27" available in oneinch increments. Fork lengths 36, 42, 48, 54, 60 and 96" with
standard tip; 84, 93, and 96"
forks available with extended-tip
design for shorter wheelbase.
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.
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.
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.
Exit roller design prevents load
wheel from dropping after crossing bottom board. The 4" wide,
steel exit roller is positioned directly behind the load wheel
to keep the fork rolling. The
entry/exit slide design also assists
in trouble-free pallet entry/exit.
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.
Pull rod design incorporates a
replaceable “tenon” design for
fast servicing of pull rod while still
in the truck.
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.
Crown provides an exclusive
5 year Supplemental Guarantee
on the Power Unit and Fork
Weldment structures.
Technical Information
e-GEN™ Braking System
Variable regenerative motor
braking is optimized and virtually
eliminates brake maintenance.
Other Options
1. Audible travel alarm
2. Flashing lights
Safety considerations and dangers
associated with audible travel
alarms and flashing lights include:
• Multiple alarms and/or lights
can cause confusion.
• Workers ignore the alarms
and/or lights after day-in and
day-out exposure.
• Operator may transfer the
responsibility for “looking out”
to the pedestrians.
• Annoys operators and
pedestrians.
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.
The closed loop Access 123
traction control will keep the
truck static until a travel input is
requested, even when operating
on a grade.
Automatic electric parking brake
activates when the truck has
been stationary for four seconds,
the truck is keyed off or the battery has been disconnected.
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.

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" 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 Crown
dealer for details.
