Crown Equipment Sit-down Rider Lift Truck FC 4500 Series - Manual (Page 8)

FC 4500 Series Technical Information
Driveability
The FC 4500 benefits from
Crown’s design and engineering
excellence. Numerous features
improve operator comfort
and productivity.
A low 18" step height first greets
the operator. A low, streamlined
battery cover helps the operator
glide into the truck’s seat. The
overhead guard is shaped to
open up the entry/exit window
and its tubular design provides a
comfortable hand grip location for
a variety of operator heights. The
compact tilt steer column and
steer wheel further facilitate
entry/exit. Tilt column is spring
loaded to easily move up and
away. Floorboard (625-sq in) is
uncluttered and rubber covered
to insulate the operator from
vibration. Sculpted floorboard
design promotes visibility to the
drive tires, which can reduce
product and pallet damage. Brake
pedal effort is reduced. Pedal to
pedal and floor to pedal relation-
ships are refined for comfort.
Better visibility can be seen
everywhere you look. A low
cowl for fork and carriage
visibility, a high visibility mast,
a compact steer column, a
sculpted floorboard and a
“waterfall” overhead guard all
contribute to superior visibility.
Control handles are crafted into
the compartment and “fanned” for
easy selection. They are
urethane covered with tactile
feedback for comfort and easy
selection. Control actuation forces
are minimal and responsive.
Finger applied/released parking
brake with tone alert enhances
operator entry/exit and naturally
encourages its use. Battery
disconnect is easy to reach and
operate. Easy to actuate rocker-
type switches are conveniently
located to select optional work
lights or fan. A large convex horn
button is housed in the center of
the wheel.
Crown Drive System
Crown has applied the latest
generation AC drive system,
enhanced with Access 1 2 3 ®
technology. The demand for
high efficiency systems that
closely match customer torque
requirements is met with this
generation control system.
Drive motor is transverse-
mounted high above the floor
away from dirt and moisture.
Heavy-duty triple reduction, all
gear design operates in oil bath.
Engineered for durability with
reduced vibration and noise.
Crown’s Access 1 2 3
technology provides optimum
performance and control by
offering a communication
interface for both operators

Mast Assembly
Large, rugged mast trunnion
mount on drive axle and extra
heavy tilt cylinders with self-align-
ing bushings secure mast.
High visibility mast features
nested-rail design with lift
cylinders positioned behind
the rails. Heavy-duty mast is
engineered to provide smooth
reliable operation. Large hydrau-
lic hose reeves and hose place-
ment are engineered to reduce
hose wear and increase hose
life. Hose routing places hoses
in-line versus side-by-side to
reduce visual interference. Large
lift chains are used for long reli-
able service life. Large diameter
lift cylinders provide smooth
operation.
Class II and III fork carriages are
available. Optional TL and quad
mast is available.
Hydraulics
Premium hydraulic function
control valve provides precise
metering of lift, tilt and acces-
sory functions. Compensating
section in the valve provides
repeatable function speed
regardless of load condition.
Hydraulic lever actuation is
minimal, reducing stress.
Compensating section also
improves overall system efficiency.
Tilt compensator prevents tilt
from lunging or speeding up when
doing simultaneous functions.
Crown lift/tilt interlock system
provides extended forward tilt
at low fork heights, reduced
forward tilt at elevated heights
to improve truck stability when
forks are elevated.
The control valves’ modular
design allows easy addition of
accessory functions. Maximum
lowering speed is limited by
pressure compensating flow
control valve and velocity fuses.
Integrated hydraulic cylinder
cushions soften mast staging.
and technicians, intelligent
coordination of lift truck
systems and simplified service
with advanced diagnostics.
The Crown display is used for
easy troubleshooting, access
event history and set perfor-
mance features. A distribution
panel is conveniently located
with all test points, control
fuses and central wiring for
easy troubleshooting.
Three modes of performance
can be selected to accommo-
date operator experience or
application requirements.
Crown Power Brake System
Service brakes are located in the
wheel ends with a unique full
circle power disc design.
Hydraulic power is utilized to
actuate a full circle rotor. This
design reduces operator pedal
effort and improves brake
response. Brake service life
is increased due to a large full
circle friction pad. Access to the
friction pads for inspection or
replacement is direct and easy,
reducing downtime for brake
maintenance. Parking brake
is activated by a push button
located on the cowl to the right
of the steer wheel column.
Tone alert reminder is standard.
Parking brake is located on the
end of the motor shaft to take
advantage of gear reduction.
Optional seat activated auto-
matic parking brake is available.
Steering
Fully hydrostatic system with
equal area, double-acting
cylinder provides equally respon-
sive steering rate both ways
(4.8 turns lock to lock). Rugged
axle frame; forged spindle and
connecting links eliminate the
need for adjustment. One-piece
forged spindle and kingpin
in tapered roller bearings for
improved life and serviceability.
Spherical bearings with tapered
pins in connecting links eliminate
any play in linkage. All bearing
locations are sealed to exclude
contaminants and are equipped
with lubrication fittings for ease
of service. Axle articulates in
rubber isolation bushing to
improve truck handling and ride.
All lift cylinder rams are plated
and retract into the hydraulic oil
for additional corrosion protec-
tion when forks are lowered.
The steel oil reservoir is integral
to the frame which helps to dis-
sipate hydraulic oil heat. This
clean, leak-free design includes
suction strainer with separate,
easily accessible fill port and
dipstick with filtered breathers.
Oil is returned through a replace-
able spin-on type oil filter.
Batteries
Battery deck lid releases easily
to expose battery for lift out or
side battery removal. Optional
battery rollers for use with
mechanized extraction equip-
ment. A low battery side retainer
is standard. Full battery side
doors are optional.
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.
