Technical Information  
SP 3470F Series  
37. Color-coded wiring  
38. 6" diameter load wheels  
39. Four-point foot print  
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

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.

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.

excellent visibility.  
 
Technical Information  
SP 3470F Series  
Travel System–continued  
Linear speed control provides  
smooth travel speed transition as  
lift heights change and increases  
productivity.  
Intelligent Braking  
Maximum lowering speed is  
regulated by a pressure com-  
pensating 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  
Polyurethane drive tire, 13"  
diameter x 5.5" wide x 8" hub  
diameter. Load wheels are  
6" diameter polyurethane x 4.25"  
wide. Optional polyurethane aisle  
guide wheels are 2" wide with a  
4" or 2.5" diameter. Casters have  
dual 3" wide x 10" diameter  
polyurethane load wheels.  
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 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.  
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 perfor-  
mance to meet specific applica-  
tion or operator requirements.  
Forks  
Standard fork is 2" thick x 4"  
wide x 36" long forged steel,  
with optional lengths available. A  
3" thick x 6" wide x 84" long box  
section fork is optional. Fork  
spread (adjustable) 24" to 30".  
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  
Pallet Clamp  
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 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.

Audible Travel Alarm Option  
Safety considerations and  
dangers associated with audible  
travel alarms include:

Power Unit  
• 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. 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.  
Crown’s intelligent steering fea-  
ture slows the truck automatically  
when the steer wheel is turned  
beyond 10°. Using the intelli-  
gence of Crown’s Access  
traction control module, the  
truck monitors the height of  
the operator platform, truck  
speed and steer wheel position.
