Several designs contribute to
better visibility everywhere you
look. A low cowl for fork visibility,
a unique waterfall overhead
guard for load handling, a high
visibility mast and a compact
steer column all improve operator
visibility around the truck.

Driveability
The SC 4500 Series benefits
from Crown’s design and
engineering excellence.
Numerous design features
improve operator comfort
and productivity.
A low 15" step height first greets
the operator. A low battery cover
that is streamlined helps the
operator glide into the truck’s full
suspension seat. The overhead
guard is shaped to open up the
entry/exit window. The compact
tilt steer column and steer wheel
further facilitate entry/exit. Floorboards are large, uncluttered
and rubber covered to insulate
the operator from vibration.
Brake and accelerator pedals are
rubber covered to provide good
grip and comfort.
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.
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.
Crown-manufactured, independently controlled, AC drive
motors are specifically designed
to optimize system integration
between the traction and
braking controls.
Crown’s Access 1 2 3
technology provides optimum
performance and control by
offering a communication
interface for operators and
technicians, intelligent
coordination of lift truck
system and simplified service
with advanced diagnostics.
The Crown display is used for
easy troubleshooting, access
service history and set performance 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 accommodate operator experience or
application requirements.
e-GEN™ Braking System
Variable regenerative motor
braking is optimized and
assisted with electric friction
brakes, eliminating maintenance
associated with typical wet,
disk or drum and shoe style
brakes. The appropriate amount
of stopping force is applied to
match operator brake input
and the current operating
conditions of the truck.
The closed loop Access 1 2 3
traction control will keep the
truck static until a travel input is
requested, even when operating
on a grade.
Automatic electric parking
brakes activate when the
operator leaves the seat, a
travel input has not been
requested or battery power
has been disconnected.
Proportional Rack and
Pinion Steering System
Hydrostatic power steering uses
a large, totally enclosed rack and
pinion gear assembly.
The steering geometry is
matched to the controller to
deliver smooth steering at all
angles. The advantage is less tire
scrubbing which extends tire life.
Both motors receive power, even
in the tightest turns. This helps
the truck to accelerate, turn and
maneuver even from a full turn
start position.
Cornering speed control
regulates the drive motor’s
output by the turning degree
of the truck. The advantage is
smooth, stable steering which
may increase operator
confidence and productivity.
Large, (15" diameter) dual steer
wheels provide good traction
and stability.
Hydraulics
The hydraulic system provides
continuous filtration. A heat
stabilized polymer hydraulic tank
is free from contamination and
retains strength over a wide
range of temperatures. Hydraulic
attachments can be added easily
in the field using modular valve
bodies. Hydraulic valve handle
actuation is precise and oil
is controlled using metered
spool valves.
Ram displacement type lift
cylinders and two double
acting tilt cylinders are
Crown-manufactured. All
rams and piston rods are
hard chrome plated to
reduce pitting and extend
cylinder packing life. O-ring
face seal fittings are used
to eliminate leaks.
Mast Assembly
Crown-manufactured mast
assembly utilizes a “flush-face”
interlocked I-beam design to
improve visibility and save truck
length. Roller bearing studs are
welded on both sides of the rails
for maximum strength and roller
bearings are canted to run in the
thick cross section of the rail. Tie
bars wrap around the rails for
added strength and to resist
off-center load forces.
SC 4500 Series
Technical Information
“In-line” hose routing opens up
visibility. Cylinders are placed
to the sides to create a high
visibility design.
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.
The mast has four points of
attachment to the truck for good
load force distribution. Two
mounting points are at the
frame, where tilt cylinders attach.
Tilt cylinders use spherical
bushings to resist off center load
distortions. Two large diameter
trunions secure the mast to
the drive units.
Drive Units
Two independent double
reduction gear drives offer
22.5 to 1 gear reduction.
The first reduction uses spiral
bevel gears for low noise and
efficiency. The second reduction
uses helical gears.The drive unit
gears are constantly lubricated
in an oil bath.
This time proven design is quiet
and reliable, providing years of
trouble-free service.
Carriage
An ITA Class II carriage is standard. An optional hook type ITA
sideshifter or other attachments
are easily added. Optional fork
lengths are available.
• 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.
Other Options Available
Contact your local Crown dealer.
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.
