Travel System
Truck performance specifications
(maximum travel speed, coast,
plugging, acceleration, travel
speed at height, and low speed
lowering) are adjustable using
Access 1 2 3. This enables cus-
tomizing 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 informa-
tion nuggets located throughout
the truck allow technicians to
troubleshoot without schematics,
wiring diagrams, or service
manuals for more than 95
percent of repairs.

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 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.

Braking can also be accom-

which permits the operator to
control the rate of deceleration
when extended stopping
distance is preferred.

Two-speed lowering (high/low)
with soft start is standard on all
models. Low speed lowering is
adjustable with the use of the
Access 1 2 3 Display. 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
steering control module.

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.

The Crown Mast Assembly
High visibility two- and three-
stage masts feature nested rail
design with lift cylinders posi-
tioned behind mast rails. Three-
stage mast has a low center
position cylinder for free lift.
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.
