Technical Information
Series WB
Hydraulic System
Drive Unit
Optional Equipment and
Modifications
1. Transistor speed control.
2. Raise and lower control on
retractable cord.
Capacities
Standard equipment includes:
Gear drive from motor to drive
wheel axle. The gear train is
mounted on ball and tapered
roller bearings, and operates in
an oil-filled, sealed housing.
Model 20WB: 2000 lb
at 24" load center.
Model 30WB: 3000 lb
at 24" load center.
Model 40WB: 4000 lb
at 24" load center.
1. Heavy duty motor and gear
pump assembled as an
integral unit.
2. Spool-type hydraulic control
valve with built-in check and
relief valve for efficient over-
load protection of lift and tilt
circuits.
3. Pressure compensating flow
control valve at base of lift
cylinder regulates maximum
lowering speed.
4. Lift cylinder diameters vary,
and are designed to maintain
optimum hydraulic pressure
depending on capacity of
truck. All WBTF and WBTT
models are equipped with a
three cylinder cluster to
provide full free lift.
5. A conveniently located
raise/lower lever is standard
equipment. This throttle per-
mits infinite control. Push but-
ton raise/lower controls can
be installed in control handle
as optional equipment.
6. Fixed flow control at side of tilt
cylinder regulates maximum tilt
speed.
7. Two double acting piston-type
tilt cylinders.
8. A conveniently located lever
for forward or backward tilt
activation is standard. This
throttle permits infinite control
of tilt functions.
3. Hour meter.
4. Higher lifting heights.
5. Additional counterweight, when
smaller batteries are used.
6. One-or two spool auxiliary
valves for controlling various
hydraulic attachments.
7. Special attachment-sideshifter,
drum handling equipment,
paper roll clamp. For other
special attachments, consult
dealer.
Brake
Internal expanding mechanical
brake with 5" drum and bonded
brake linings. Brake is applied
when control handle is within 15°
of full vertical or full horizontal
position.
Maximum Battery Size
31.75" wide x 13.12" long x
23.25" high.
Batteries
Up to 600 amp hour capacity
available. 24 volt electrical sys-
tem. The 20WB, 30WB, and
40WB must have a battery
weighing 975 lbs or more.
Power Unit Structure
Access panel permits easy
entry to all electric and hydraulic
components.
8. Discharge indicator.
Travel Speeds
Lift Structure
In third speed: Loaded, 2.5 mph;
Empty, 3.0 mph. These speeds
are average for all Walkie
Other Options
1. Audible Travel Alarm.
2. Flashing Lights.
Outer and inner masts con-
structed of hot rolled carbon steel
I-beam. Telescoping mast section
nests in main upright to provide
better visibility for operator.
Counterbalanced trucks. For
safety, third speed is automati-
cally shut off when forks reach
68" on WBTL models, or when
forks extend above free lift on
WBTF and WBTT models.
Safety considerations and dan-
gers 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.
Carriage Rollers
Alloy steel rollers contoured to fit
mast are equipped with sealed
ball bearings.
Lifting/Lowering Speeds (fpm)
Control Handle
Empty (E), Loaded (L)
Control handle has dual twist-
grips which control three speeds
forward and reverse. Twist-grips
return to neutral when released.
The handle contains a large
safety button which reverses the
direction of the truck should the
button touch the operator. A
large horn button is standard
equipment, as is a third speed
cutoff switch.

how it is equipped and the con-
ditions of the operating area.
