RC 5500 Series Technical Information
e-GEN™ Braking System
Variable regenerative motor
braking is optimized and virtually
eliminates brake maintenance.
The appropriate amount of
stopping force is applied to
match operator brake input
and the current operating
conditions of the truck.
The closed loop Access 1 2 3
traction control will keep the
truck static until a travel input is
requested, even when operating
on a grade.
Automatic electric parking
brakes activate when the
operator releases the brake
pedal, a travel input has not
been requested or battery
power has been disconnected.
Steering
Load-sense hydrostatic
steering is an on-demand
system which reduces energy
consumption. Smooth, quiet
steering control with minimal
operator effort required at the
steer tiller. Steer tires rotate 182º
for maximum maneuverability.
Crown’s hydrostatic steering
system is simplified with signifi-
cantly fewer parts, thus reducing
maintenance requirements.
Hydraulics
The hydraulic system provides
continuous filtration. A pressur-
ized steel hydraulic tank reduces
oil misting and contamination.
Hydraulic attachments can be
added easily in the field.
Hydraulic manifold is mounted
on the mast reducing the number
of hoses and fittings.
Ram displacement type lift
cylinders and two double
acting tilt cylinders are
Crown-manufactured. All
rams and piston rods are
hard chrome plated to
reduce pitting and extend
cylinder packing life. O-ring
face seal fittings are used
to eliminate leaks.
Mast Assembly
Crown-manufactured mast
assembly utilizes a “flush-face”
interlocked I-beam design to
improve visibility and reduce
truck length. Roller bearing studs
are welded on both sides of the
rails for maximum strength and
roller bearings are canted to run
in the thick cross section of the
rail. Tie bars wrap around the
rails for added strength and to
resist off-center load forces.
“In-line” hose routing opens up
visibility. Cylinders are placed
to the sides to create a high
visibility design.
The mast has four points of
attachment to the truck for good
load force distribution. Two
mounting points are at the
frame, where tilt cylinders attach.
Tilt cylinders use spherical
bushings to resist off center load
distortions. Two large diameter
studs secure the mast to the
drive units.
Drive Units
Two Crown-manufactured
independent double reduction
planetary gear drives offer
27 to 1 gear reduction. The
first and second reduction
use helical gears for low noise
and efficiency. The drive unit
gears are splash lubricated in
an oil bath.
Carriage
An ITA Class II carriage is stan-
dard. An optional hook type ITA
sideshifter or other attachments
are easily added. Optional fork
lengths are available.
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.
