Performances are of trucks with 410 lb (185 kg)
industrial battery and 200 lb (91 kg) battery pack.
Performance may vary +5% or -10% due to motor,
tire, drive unit and hydraulic efficiency tolerances
and battery weight.

For Your Safety
•Do not operate motorized hand trucks unless
you are trained and authorized. Read and
understand the operator’s manual before
operating.
•Do not operate a damaged or faulty truck. Do
not attempt repairs unless you are trained and
authorized.
•Keep hands on designated grips and feet away
from truck. Do not operate truck with wet or
greasy hands or shoes.
•Enter confined areas with load end first. Be
very careful when operating in confined areas
to avoid being pinned.
•Avoid uneven or slippery surfaces and loose
materials.
•Travel slowly and with caution on slopes and
do not turn. Always travel with load end down
grade.
•Do not load truck over capacity on nameplate.
Do not handle unstable loads. Be very careful
when handling long, high, or wide loads.
•Do not exceed floor weight limits.

Clark WP 45 electric low-lift pallet trucks are ideal for moderate duty
cycles. Their quiet operation, and clean self-contained hydraulic
systems make them ideal for most indoor work areas. Their low initial
cost, ease of maintenance and 24-volt electrical system make
them an economical alternative to hand pallet jacks.
Operator Comfort/Convenience
•Formed steel handle with closed loop design
•All controls at operator’s fingertips
•International symbols identify functions
•Smooth, stepless speed control in forward and reverse
•Reversing switch in handle
The enclosed handle with designed-in hand guards is especially
convenient in tight workspaces. It allows control from either side of the
truck and provides excellent hand protection. The smooth
contours help prevent snagging on clothes, posts, doorways,
machinery or adjacent loads.
Direction, speed, lift/lower and horn controls are located on the
handle, marked with international symbols.
Reversing switch at the end of the handle is spring-loaded and
designed to override the directional control, automatically reversing
the truck on contact.
The directional control is thumb actuated and designed for left or right
hand operation.
Motors
Drive motor is 6.6 in. diameter, fan cooled and has class “H” insulation
for increased protection from heat damage. 24-volt drive motor is
separately excited (shunt wound).
Hydraulic motor is 4.5 in. diameter with class “H” insulation and
vertically mounted.
Electrical Systems
•Infinitely variable, separately excited transistor drive control
•24-volt operation
•Utilizes convenient battery pack with built in charger or
industrial battery (neither included in truck price)
•100 amp contactors
•Automatic resetting circuit breakers
•Easy access for inspection and testing
The separately excited control allows elimination of the forward and
reverse contactors. This control has many features designed to
improve productivity and serviceability including: programmable
neutral braking, creep and top speeds, variable plugging and
diagnostics to facilitate troubleshooting.
Wiring through the handle is contained in a heavy-duty harness
designed to last without undue binding, chafing or twisting.
A battery pack is optional and eliminates the need for special charging
equipment. It consists of a steel tray that holds four 6-volt, deep cycle,
heavy-duty batteries and a built-in charger. The charger plugs into any
grounded 110 volt AC outlet for quick, economical recharging of
batteries. The steel tray features hinged, swing-out top batteries for
easy bottom battery maintenance. Maintenance free batteries are also
available. Units equipped with either battery pack cannot carry UL
label.
•Battery pack provides 3.52 kwh with a 152 amp hour rating
(maintenance free battery pack provides 4.6 kwh with 195 amp
hour rating) and is equipped with a SB-175 red connector.
•Industrial battery - 12 cell 7 plate, 25.7 in. x 8.9 in. x 23.3 in. (653
mm x 226 mm x 592 mm) battery provides up to 7.6 kwh.
Drive Line
•Double reduction helical and spur gears
•Totally enclosed
•Protected location
Power from the horizontally mounted drive motor is transmitted
through 22 to 1 double reduction helical and spur gears to the drive
wheel axle. The gears are mounted on ball and tapered roller bearings
and operate totally enclosed in a bath of oil. Drive wheel is mounted
on a spline type axle and secured with a single, heavy duty lock nut for
quick change in the field.
Brakes
•Double acting
•Self adjusting
Brake is actuated by positioning the handle up or down. In either
position, the motor shuts off as the brakes are applied. When the
handle is released a heavy spring and chain return it to the vertical
position which applies the brake for parking. Brake pads are self-
adjusting and easily replaced.
Hydraulic System
•Integral pump and motor
•Simple hosing
•Serviceable cylinder
Hydraulic pump, motor, fluid reservoir, relief valves and inlet filter are
completely integrated, eliminating most of the connections associated
with hydraulic fluid leaks. Plumbing consists of a single, non-flexing
hose from the pump to the lift cylinder. The cylinder is a single acting,
ram type with an easily removable wire ring retainer for easy seal
replacement.
Steering
•Handle rotates drive unit 180°
•Design assures positive control
Long steer handle with low pivot point provides increased leverage to
reduce steering effort. Rectangular tubular design prevents handle
flexing and improves control.
Frame and Chassis
•Formed, unitized steel
•Uniquely tooled fork design
Major components of the truck frame are formed steel, resulting in
superior strength at reduced weight. Forks are one piece steel
sections designed for added rigidity to increase service life. Frame
provides single point mounting of hydraulic cylinder and drive unit,
absorbs stress of lifting/lowering and travel. All exposed surfaces are
covered with a highly durable powder coat, free of chromium and lead.
This finish is smooth, easy to clean and resistant to chipping, rust and
corrosion.
Standard Equipment
Full 6” lift; 24-volt separately excited transistor control, rubber drive
tire with string guard; poly load wheels; poly skid stabilizers; horn; key
switch; BDI and 27 in. x 48 in. (686 x 1220 mm) forks. Finish is high-
visibility Clark green with black.
Options
Battery pack (standard or maintenance free batteries); poly drive tire;
various fork lengths from 32” (813 mm) to 60” (1524 mm) and widths
from 18” (457 mm) to 27” (686 mm), 48 in. (1220 mm) and 60 in. (1525
mm) load backrests; hour meter/BDI combination; cold
storage/corrosion conditioning, UL “E” and“EE” construction (“E”
