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.

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 warrant
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.

Technical Information
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.

e-GEN
Braking System
Variable regenerative motor braking is optimized and virtually eliminates brake maintenance.
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.

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.

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.
