Capacities

Model 20WB: 2000 lb

at 24" load center.

Model 30WB: 3000 lb

at 24" load center.

Model 40WB: 4000 lb

at 24" load center.

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.

Travel Speeds

In third speed: Loaded, 2.5 mph;

Empty, 3.0 mph. These speeds

are average for all Walkie

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.

Wheels and Tires

Polyurethane Drive Tire - 13" dia

x 4.5" wide x 8" dia hub.

Rubber Drive Tire - 13.5" dia x

5.5" wide x 8" dia hub.

Load Wheels - 10" dia x 4"

wide x 6.5" dia hub. 40WB load

wheels are 5" wide. Polyurethane

load wheels on 30WB and

40WB, rubber power saver

compound standard on

20WB models.

Forks

Fork carriage standard ITA

Class II hook type mounting.

Fork lengths - 30", 36", 42" and

48". Fork spread - adjustable

33" maximum, 8" minimum.

Drive Unit

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.

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.

Power Unit Structure

Access panel permits easy

entry to all electric and hydraulic

components.

Lift Structure

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.

Carriage Rollers

Alloy steel rollers contoured to fit

mast are equipped with sealed

ball bearings.

Control Handle

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.

Safety Switches

1.Third speed switch in control

handle may be used to shut

off high speed when operating

in congested areas.

2.Limit switch automatically

reduces maximum travel

speed immediately upon

extension of second and third

stages on WBTF and WBTT

models, and when forks

extend above 68" on WBTL

models.

3.Reversing button on control

handle reverses direction of

travel when actuated by the

operator.

Hydraulic System

Standard equipment includes:

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.

Electrical System

Standard equipment includes:

1.24 volt electrical system.

2.Series wound high torque

.85 hp drive motor.

3.Series wound high torque

5 hp lift motor.

4.Heavy duty pump contactor

with replaceable tips.

5.Four heavy duty travel speed

contactors. A solid-state time

relay provides controlled

acceleration between 2nd

and 3rd speed.

6. Fused control and power

circuits.

7.Color coded wiring for ease

of service.

8.Key switch.

9.Power disconnect lever.

Optional Equipment and

Modifications

1.Transistor speed control.

2.Raise and lower control on

retractable cord.

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,

paperro ll clamp. For other

special attachments, consult

dealer.

8.Discharge indicator.

Other Options

1.Audible Travel Alarm.

2.Flashing Lights.

Safety considerations and dan-

gersassociated 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.

Dimensions and performance

data given may vary due to

manufacturing tolerances.

Performanceis based on an

average size vehicleand is affect-

ed by weight, condition of truck,

how it is equipped and the con-

ditions of the operatinga rea.
