Material handling solutions that deliver Quality, Reliability and
superior Customer Service are what you’ve come to expect from Cat®
lift trucks. Whether you’re hauling pallets of packaged foods, stocking
shelves, or loading manufactured goods for shipment, there is a Cat
electric walkie to get the job done smarter, better, faster. These 3,000­
6,000 lb capacity electric walkies are designed to meet the challenges
of rough-and-tumble real-world environments like yours. The tough and
rugged 6,000 lb capacity model is compact and easy to maneuver,
managing hefty loads easily, even in tight quarters. The versatile 4,500
lb capacity and light-duty 3,000 lb capacity Alternating Current (AC)
electric walkies offer dependable performance with clean AC drive
motors. From their rugged, torque-resistant frames, premium Vulkollan®
tires and impact-resistant control handles, these trucks are built with
quality. With the shortest head lengths in the industry for vehicles of
their size and class, these trucks are highly maneuverable for improved
productivity. Low maintenance requirements help to ensure an excellent

robust chassis and load section meet the needs
of hard-working applications.
The frames on all three models have been
rigorously tested, fully loaded, at 100 percent of
their rated capacity for 60,000 cycles to ensure
dependable performance. Solid steel forks offer
exceptional durability in comparison to bent­
and-formed steel designs. For improved grease
retention and reduced maintenance, readily
accessible grease fittings and dimpled bushings
are standard at each pivot point on the 6,000 lb
truck (shown above) and on the 4,500 lb model.
The heavier duty models also offer added-value
features such as stability casters with Vulkollan
tires, which provide excellent lateral balance,
even when traveling at full capacity.

Walk A Tight Line
These electric walkies improve your productivity in more
ways than one. With the shortest head length in the
industry, every one of these models offers a turning
radius so tight that pin-wheeling in a trailer is a breeze.
The compact WP4500 model (shown here), with its head
length of only 21.7 inches (550 mm), makes turning easy
while leaving you more room to pack more product into
every trailer.
4
Powered To Meet Your Needs
A maintenance-free battery with a built-in charger
(standard on the WP3000 electric walkie and
available on the WP4500 electric walkie), is enclosed
in its own compartment for protection against
moisture and dirt. For information concerning the
standard and optional battery packages for all
models, consult your dealer.
Driven To Perform
The powerful WP4500 model uses innovative
3-phase AC technology with a high efficiency factor
to optimize energy resources. Energy efficiency is
further enhanced through advanced regenerative
braking, which recovers energy while the truck is
slowing. The advanced regenerative braking also
provides very smooth directional changes while
reducing brake-pad wear. The drive motor controller
can be programmed to meet the specific speed and
acceleration requirements of your application.
The AC motor is brushless and virtually
maintenance free.
5
WP4500 Options
• A comprehensive selection of fork lengths
and widths
• A combo battery discharge and hour meter, with a
fault display for diagnosing problems
• Optional key pad access so that you can program up
to three modes of performance at the touch of
a button
• Roomy battery compartment for even greater
amp-hour capacity
• Spring Loaded Torque-tube (SLT) casters
• Load backrest extension to minimize the shifting of
loose loads during operation
• Freezer package
Ramp Up
These dynamic vehicles let you ramp up your
expectations a notch, delivering consistent performance,
whether empty or loaded. All electric walkies offer
exceptional torque, with smooth starts and stops, and
great speed control. Regardless of the position of the
control handle, the brake sets automatically to prevent
unintentional roll-backs, providing secure operations
when operating on ramps.
6
Get Excited
Quality is built into every feature of these electric
walkies. Don’t be fooled by their compact size. Inch for
inch, the WP6000 (shown here) performs like a champ,
with durability that’s second to none, and a short head
length for great manueverability.
Take Control
WP6000 Options
Multi-functional, ergonomically designed control
• A comprehensive selection of fork lengths and widths
handles protect the hands of your operators while
• Large battery compartment
allowing them to lift, lower, and travel comfortably.
• Hour meter with battery discharge indicator
On the WP6000, the control handle comes with the
• Key pad access
added benefit of dual controls, optimizing efficiency
• Stability casters
and helping to reduce worker fatigue by allowing the
• Load backrest extension to minimize
operator to use either hand for control of the lift and
lower functions. Crawl speed, standard on all models,
the shifting of loose loads during operation
• Freezer package
enables travel when the control handle is in the vertical
position; when the crawl speed button is pressed and
travel is requested, the controller releases the electric
brake to allow travel. This feature significantly reduces
travel speed to assist your operator and the load, while
allowing operation in very tight areas.
7
Moving On Up
If you’re still using manual hand pallet trucks, you’ll be
impressed by the low cost of ownership of these low­
maintenance electric walkies. As the newest member of
the electric walkie family, the light-duty WP3000 allows
your operators to move materials with less strain, effort,
and fatigue. The short head length ensures excellent
maneuverability, making it easier for operators who are
accustomed to manual hand pallet trucks to efficiently
transition up to an electric walkie.
Dollars And Sense
The WP3000 comes with durable, 50 amp-hour
Pictured: WP3000 Battery (located in the
bumper well)
capacity, maintenance-free batteries that provide up to
one full hour of continuous use per day. An integrated
battery charger, with extension cord, can be connected to
any 120-V AC outlet for convenient recharging.
The AC motors on both the WP3000 and WP4500 are
brushless, so no brush maintenance is required.
8
WP3000 Options
• A comprehensive selection of fork lengths and widths
• More robust electro-magnetic horn (quieter, electronic
horn is standard for noise-sensitive environments)
Stop Worrying
These electric walkies feature an electro-magnetic brake
that acts directly on the motor shaft to hold the truck
stationery or to stop the truck quickly when necessary.
Whenever the control handle is released, or the travel
control is returned to neutral, the truck will automatically
come to a stop and set the electric brake. By moving the
handle into the operating position and requesting travel,
the brake will release and the electric walkie will resume
operations, moving smoothly in the direction requested.
