ST/SX 3000 Series
Technical Information
Operator Controls
The control hand grips are
urethane covered for insulation
from cold and vibration. Full
function control handle includes
travel direction, raise, lower and
reversing switch.
The physical efforts to hold the
handle at a comfortable height
was minimized to reduce fatigue
a distinct advantage. The
operator is positioned to
maximize the steer effort and
maintain excellent visibility.
The rabbit/turtle switch
incorporates two levels of
programmable travel performance
to match operator experience
and application environment.
Exclusive brake override allows
slow speed travel with the
handle near vertical. This feature
improves maneuverability in
tight areas.
Performance
The ST/SX 3000 Series benefits
from Crown’s design and
engineering excellence.
The transistor control module
works in conjunction with a new
separately excited (SEM) drive
motor to provide excellent acceleration and top travel speed
loaded or empty. Transistor
control is programmable for
specific tasks or operator
skill levels.
Smooth travel and lift combine
with excellent controls to reduce
product damage and increase
productivity.
Electrical System
A heavy-duty 24-volt fused
electrical system provides good
travel and lift speeds.
Separately excited motor control
eliminates directional contactors
reducing maintenance and
downtime.
The transistor control is sealed
from dirt, dust and moisture for
trouble-free operation. Transistor
control features include overtemperature protection, polarity
protection, self-test and visible
diagnostics.
Regenerative motor braking is
activated under a downhill condition, during plugging or when
the directional control is returned
to neutral. “Regen” reduces heat
build-up and extends motor
brush life.
An anti-roll down feature will
apply the brakes if the truck rolls
without a travel command.
175-amp battery connector with
standard disconnect handle.
Hydraulic System
Heavy-duty hydraulic motor
(ST–2.2 kw, SX–3.0 kw) with
integral pump and reservoir for
maximum efficiency and
durability.
Single-speed lift and two-speed
lowering is available to the
operator.
Cylinder rods are hard-plated
chrome with polyurethane seals.
Relief valve tuned to capacity
protects all components in the
hydraulic system.
Drive Unit and Brakes
Heavy-duty gearbox with spur
gears for low noise emission.
Drive unit is equipped with an
electromagnetic disc brake that
is spring applied and electrically
released. Brake is activated by
the control handle position.
Brake rotor and disc are easily
accessed for inspection and
replacement. Regenerative motor
braking assists brake effort and
improves component life.
Drive unit mounts in truck frame
with a permanently lubricated,
twin-conical roller bearing that
disperses load forces evenly,
reducing maintenance and
downtime.
Mast
High visibility two- and threestage mast design features
nested I-beams and canted
rollers. Lift cylinders are positioned in outer I-beam profile for
best visibility through the mast
and clear view onto fork tips
during load handling. Mast
cushioning between stages
ensures smooth operation.
Heavy-duty mast and chain
rollers are sealed and lubricated
for life. Mast design allows for
easy access to carriage rollers.
Fork Carriage
ST 3000 Series feature 25" wide
pin-type fork carriage. Forks are
adjustable from 6.5" to 24.8".
Standard fork lengths are 36",
42" and 48".
SX 3000 Series feature a standard 32" wide ITA Class II fork
carriage. Forks are adjustable
from 10" to 31". Standard fork
lengths are 36", 42" and 48".
Ser viceability
One-piece steel power unit
cover is removed easily for
access to all major components.
Brake rotor and disc inspection
and replacement are easy.
Drive motor brush access is
excellent.
Color-coded wiring speeds
troubleshooting and the transistor control module uses visible
LED flashes for fault communication. Optional plug-in hand
set analyzer for servicing and
programming capability.
Control handle switch cap is
easily removed to expose
components.
Wheels and Tires
• Drive tire – Vulkollan
10" dia x 3.35" wide
• Load wheels – Vulkollan
4" dia x 2" wide (ST)
4" dia x 3" wide (SX)
• Optional poly casters are
3.5" dia x 2" wide
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.
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.
