Operator Platform
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 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.
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.
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 unau-
thorized operation of the truck.
The Access 1 2 3 Display Panel
provides concise, clear feedback
for the operator during truck
operation.

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.
• Interactive Display Module
• Traction Control Module
• Vehicle Control Module
• Steering Control Module
• Guidance Control Module
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.
Fixed, mounted drive motor does
not rotate minimizing wear on
electricall cables. Drive tire
changing is simplified with this
drive unit.
Crown’s AC Drive system dra-
matically improves travel speeds,
acceleration and deceleration,
thus increasing productivity.
The standard linear speed control
provides smooth travel speed
transition as lift heights change
and increases productivity.
