Operator Platform
Crown’s Access 1 2 3...
The Comprehensive Access 1 2 3
System Control is a modular
based communications and
control system. It monitors all
on-board sensors, makes
decisions based on the sensor
readings, and subsequently, con-
trols all system movements safely
and smoothly. All five modules are
in constant communications with
each other via a CAN (Control
Area Network) bus so that real
information is accessible to the
system at all times.
®
1. Crown’s Access 1 2 3
The operator area is designed for
maximum visibility and stability for
increased operator confidence
and comfort.
Comprehensive System Control
2. Crown’s AC traction

The operator platform features
a large window (1088 sq in) for
excellent visibility. A Crown-
designed clear-visibility mast
affords the platform window one
forward and two peripheral win-
dows for maximum visibility, even
when the platform is lowered.
3. 24-volt electrical system
4. Electronic steering

Crown Drive System
Crown has applied the latest
generation AC drive system,
enhanced with Access 1 2 3
technology. A Crown-manufac-
tured drive unit uses spiral bevel
and helical gears from motor to
drive wheel axle.
(non-wire guided trucks)
A soft urethane twist grip is solidly
mounted to the truck console to
provide excellent stability for the
operator during travel, plugging
and braking. Controls for lift/lower,
horn and emergency disconnect
are conveniently located for
efficient operation and minimal
operator fatigue. The steering
wheel is angled at 10° and
recessed to maximize the work
area and reduce steer effort. The
steering wheel and spinner knob
are covered with soft urethane to
reduce grip force and insulate
against vibration. Control location
keeps the operator’s posture
neutral at all times.
6. Battery retainer

15. Premium platform cushion
The platform cushion, made of
a microcellular composition,
absorbs shock and vibration.
The brake pedal has a low-profile
design and when engaged is flush
with the platform cushion for
maximum comfort. Heavy-duty

and one vertical support rails,
communicate security to the
operator. For additional safety,
cut-out switches disengage
truck operation when side gates
are raised.

Travel System
Intelligent Braking System
(IBS)
compensating flow control valve.
Velocity fuses are used in all
cylinders to stop lowering should
lowering speed exceed a preset
value due to a line rupture. A
hydraulic accumulator is used to
cushion raise and lower func-
tions. Manual lowering control on
manifold block allows lowering of
platform from ground level. Oil
reservoir is designed with a 100
mesh screen at the fill location,
a suction strainer, spin-on type
10 micron return line filter and a
magnetic drain plug.
Wheels and Tires
Truck performance specifications
(maximum travel speed, coast,
plugging, acceleration, travel
speed at height, and low speed
lowering) are adjustable using
Access 1 2 3. This enables cus-
tomizing truck performance to
meet specific application or
operator requirements.
Polyurethane drive tire, 13"
diameter x 5.5" wide x 8" hub
diameter. Tandem load wheels
are 6" diameter polyurethane
x 2.8" wide (4.25" wide for lift
heights above 348"). Optional
polyurethane aisle guide
wheels are 2" wide with a 4"
or 2.5" diameter.
Crown’s patented Intelligent
Braking System combines
motor braking with optimum
amounts of friction braking
(three varying levels of force).
The appropriate level of braking
is applied dependent upon plat-
form height, direction of travel,
and truck weight. Braking force
is automatically reduced as
height increases and speed
decreases. Optimum braking
for the right elevation gives
operators more confidence and
better control, while eliminating
abrupt stops and reducing plat-
form sway. Brake lining life can
be expected to last up to twice
as long before replacement
is necessary.
Forks
Crown’s InfoPoint system offers
evolutionary refinement for
service simplicity. The InfoPoint
Quick Reference Guide, on-truck
component maps and informa-
tion nuggets located throughout
the truck allow technicians to
troubleshoot without schematics,
wiring diagrams, or service
manuals for more than 95
2" thick x 4" wide forged steel.
Fork spread (adjustable) 24" to
30". Standard length is 36".
Optional lengths available.
Pallet Clamp
The Crown Mast Assembly
High visibility two- and three-
stage masts feature nested rail
design with lift cylinders posi-
tioned behind mast rails. Three-
stage mast has a low center
position cylinder for free lift.
Routing of hosing and cables
optimizes visibility through mast.
Built-in sensors detect chain
slack and shut down primary
lower function. Exclusive
spring-loaded staging bumpers
virtually eliminate platform
impact as platform stages.
Negative rail drop allows shim-
ming of mast rollers without
major disassembly.
Standard equipment includes a
foot-applied, hand-released pallet
clamp designed for use with
pallets having center stringers.
Safety Shield
percent of repairs.
Safety glass to protect operator
from chains and moving parts
while in his normal operating
position.
The InfoPoint Quick Reference
Guide provides code definition
and overall component ID so
the technician knows what it is,
where it is, and what it does
(Three W’s). InfoPoint ensures
faster, simpler, and higher
quality service.
Braking can also be accom-
plished by proportional plugging,
which permits the operator to
control the rate of deceleration
when extended stopping
Audible Travel Alarm Option
Safety considerations and
dangers associated with audible
travel alarms include:
distance is preferred.
Simplified Hydraulics
• Multiple alarms can cause
confusion.
Heavy-duty series wound pump
motors and gear pumps are
assembled into an integral unit.
High-speed lift is standard on
SP 3520 and SP 3550H models.
Crown-manufactured solenoid
type manifolds with built-in
checks and relief valves.
Intelligent Steering
Standard on the SP 3500
Series is electronic steering
that is microprocessor based.
• Workers ignore the alarms
after day-in and day-out
exposure.
Stronger Low Profile
Power Unit
Crown’s intelligent steering fea-
ture slows the truck automatically
when the steer wheel is turned
beyond 10°. Access 1 2 3 moni-
tors the height of the operator
platform, truck speed and steer
wheel position.
• Operator may transfer the
responsibility for “looking out”
to the pedestrians.
Power unit is fabricated from
heavy-gauge steel. Lower skirt
is .75" steel that runs 9" high for
component protection. Rugged
steel doors suspended on
heavy-duty pin hinges cover
power unit componentry. Doors
swing wide for open access.
Doors can also be lifted off for
unrestricted service access.
Door bolts have exclusive
convex design that mates with
concave door holes for fast
reinstallation of door bolts.
Battery side covers are all steel.
An optional battery retainer
interlock switch is available. Top
battery access is available by
lifting cover. Cover has integral
support post.
Two-speed lowering (high/low)
with soft start is standard on all
models. Low speed lowering is
adjustable with the use of the
Access 1 2 3 Display. Soft-start
lowering feature reduces the
harshness at the beginning and
end of the lowering cycle. The
softer start is accomplished by
controlling how quickly the
proportional valve is opened
or closed. Valve actuation is
controlled by a driver in the
steering control module.
• Annoys operators and
pedestrians.
