Guide and Maps
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. 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 side gates, with
two horizontal and one vertical
support rails, communicate
security to the operator. For
additional safety, cut-out
switches disengage truck
operation when side gates are
raised. Two work lights, two
dome lights and a two-speed fan
are optional. “Power-on” key
prevents unauthorized operation
of the truck; start position
initializes truck “self-test”.
The Information Display Panel
provides concise, clear
feedback for the operator
during truck operation.
Responsibly Innovative
Electronics
Environmentally hardened
heavy-duty 24-volt electrical
system. The system utilizes an
intelligent network of modules
to provide real time truck
control, display, diagnostics and
calibration. A distribution panel
provides a central location for
troubleshooting, reduces wiring
requirements, and enables future
options to be added easily. The
control system can be accessed
by the Service Terminal to provide
calibration of truck parameters
and optional features set-up.
The control system is also used
to extract service diagnostic and
management data. The link-up
port is conveniently located
on the platform and is easily
accessible without removal of
covers for connection.
The Crown Program Analysis
Cartridge (PAC) works in
conjunction with the Service
Terminal and ensures users
simple, fast program upgrade
of systems.

Human Factor
The operator area is designed for
maximum visibility and stability for
increased operator confidence
and comfort.
The operator platform features a
large window (1088 sq in) for
excellent visibility. A Crowndesigned clear-visibility mast
affords the platform window one
forward and two peripheral windows for maximum visibility, even
when the platform is lowered.
The clear-visibility mast, with
full free lift, extends the platform
window above the mast
channels for unobstructed
visibility when raised.
A low-profile power unit, low
placement of the lower cross
brace and an outer C-channel
rail assembly also contribute to
excellent visibility.
Information Display Panel
The Information Display Panel
travels with the operator at all
times. Features include audible
and visual prompts for the
operator, steer wheel direction
indicator, battery fuel gauge with
lift interrupt, wire guidance status
lights, hour meters for all motors,
brush wear indicators and motor
temperature indicators, elapsed
time counter, optional battery
retainer interlock light, and
optional fork height “zone
select” control.
The Service Terminal also provides extensive service history
information as well as “real time”
electrical system diagnostics
and fault isolation information
for servicing.
Enhanced and
Interchangeable Drive Unit
A Crown-manufactured drive unit
uses spiral bevel and helical gears
from motor to drive wheel axle.
Fixed, mounted drive motor does
not rotate minimizing wear on
electrical cables. Drive tire
changing is simplified with this
new drive unit. Crown Turret
Trucks and Reach Trucks also
use this drive unit.
Four-wheel Configuration
A drive tire, caster wheel, and two
load wheels provide a four-point
foot print. Caster is adjustable to
compensate for tire wear.
Travel System
Crown’s exclusive Access
traction control module
dramatically improves travel
speeds, acceleration and
deceleration, thus increasing
productivity. The network of
modules knows the position
of side gates, the speed and
direction of travel, the position of
the steer wheel, the truck weight
and the height of the operator
platform. The traction control
module uses this information to
control acceleration, braking,
plugging and maximum speed.
The Crown traction system
provides high available torque
utilizing a Crown manufactured
separately excited motor and
maintains constant performance
levels under varying loads, conditions and battery state of charge.
Speeds remain the same empty
or loaded. Separately excited
motor technology eliminates
forward, reverse and bypass
contactors achieving higher
levels of reliability. Regenerative
motor braking helps save energy,
increases motor brush life and
decreases motor temperature.

Technical Information
Travel System–continued
Linear speed control provides
smooth travel speed transition as
lift heights change and increases
productivity.
Truck performance specifications
(maximum travel speed, coast,
plugging, acceleration, travel
speed at height, and low speed
lowering) are adjustable using the
Crown Service Terminal. This
enables customizing truck performance to meet specific application or operator requirements.
Crown’s InfoPoint system offers
evolutionary refinement for
service simplicity. The InfoPoint
Quick Reference Guide, on-truck
component maps and information nuggets located throughout
the truck allow technicians to
troubleshoot without schematics,
wiring diagrams, or service
manuals for more than 95
percent of repairs.
The InfoPoint Quick Reference
Guide provides code definition
and overall component ID so
the technician knows where it is,
what it is and what it does
(Three W’s). InfoPoint ensures
faster, simpler, and higher
quality service.
Intelligent Steering
Standard on the SP 3400
Four-Point Series is electronic
steering that is microprocessor
based.
Crown’s intelligent steering feature slows the truck automatically
when the steer wheel is turned
beyond 10°. Using the intelligence of Crown’s Access
traction control module, the
truck monitors the height of
the operator platform, truck
speed and steer wheel position.
Steering wheel rotation provides
smooth, operator feedback. Steer
effort is minimal, lock-to-lock
revolutions is 4.5 turns. Drive
wheel rotates a full 180° for
maximum maneuverability. Auto
centering drive tire for trucks
equipped with rail guidance.
Steering is connected to the
Control System for full
diagnostics and operator
interface. Crown PAC also
interfaces with steering system
for fast upgrade.
Intelligent Braking
System (IBS)
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 platform 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 platform sway. Brake lining life can
be expected to last up to twice
as long before replacement
is necessary.
Brake system eliminates
hydraulic lines running in mast to
control braking. Braking can also
be accomplished by proportional
plugging, which permits the
operator to control the rate of
deceleration when extended
stopping distance is preferred.
Simplified Hydraulics
Heavy-duty series wound pump
motors and gear pumps are
assembled into an integral unit.
Two-speed lift (high/low) is
standard. Crown-manufactured
solenoid type manifolds with
built-in checks and relief valves.
Two-speed lowering (high/low)
with soft start is standard. Low
speed lowering is adjustable with
the use of the Service Terminal.
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
networks
traction control module.
Maximum lowering speed is
regulated by a pressure 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 functions. 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.
The Crown Mast Assembly
High visibility three-stage mast
features nested rail design with
lift cylinders positioned behind
mast rails. Mast has a low center
position cylinder for free lift.
Improved mast cable life due
to larger, 5" diameter pulleys.
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 shimming of mast rollers without
major disassembly.
Stronger Low Profile
Power Unit
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.

while in his normal operating
position.
Audible Travel Alarm Option
Safety considerations and
dangers associated with audible
travel alarms include:
• Multiple alarms can cause
confusion.
• Workers ignore the alarms
after day-in and day-out
exposure.
• Operator may transfer the
