PPI-90 series Pallet Inverter is a new storage battery
designed power lifter / rotator based, which is made of

three parts （ fuselage with battery, footplate, rotator

amework）. Its main function is to lift or load the logo

fr
from floor and make it to move and rotate. It is adopted

the originally imported electrical control equipment
which consists of unit components such as
microprocessor. It is specially adapted for printing and
relevant outdoor or indoor operation owing to their
functional perfection and high reliability.

1）Structured feature

As the entirety weld, fuselage has a compact structure and high
strength. The electrification controller and the hydraulic part are
both put on the back panel in the truck and with the reasonable
rotator frame design, it is convenient to maintain. It has high
function, no pollution, and low price, and high efficiency, durable
and reliable feature. The new-type battery box can correctly
inspect the capacity and the status of battery. With the drive wheel,
it comes to move ahead or backward.

The implement of main function:

Paper lift / rotator:

Battery -- Electric Controller – Hydraulic Motor-- Gear Pump –

Controller Valve – Cylinder – Fork clamp – Paper clamp –Lift
Cylinder – Paper Rotate

Paper fall/ rotator:

Battery --Electrification Controller –Solenoid Valve changed the

direction – Cylinder loads the oil -- Paper Rotate

Drive Move:
Battery --Electrification Controller – Drive motor changes the

speed – Reduce the speed of gear box - Drive wheel rotated –
Stacker moves

2））））Operation

The control switches of turning, clamping, up and down, forward
and backward, push the horn are all designed on the handle. You
can operate the truck easily. If you push down the handle and
revolve the knob forward or backward, the truck will move ahead
or backward along with your movement. When you free your
hand from hold of the handle or push the handle down to the
lowest level then the truck will automatically turn to brake state.

3

As you begin to operate the truck, open the power with

switch key to turn on the current. A dial of battery volume will
show the electrical volume of batteries. According to the
requirements of loading or unloading, push the relevant switch to
control the truck. The speed regulation must be made slowly to
avoid accidents.

It is strictly forbidden to turn the drive wheel in the air with
in the current for a long time. Otherwise, it may possibly damage
the drive motor in overheat.

3））））Security system

PPI-90 Paper Inverter’s are equipped with automatic brake

system. The brake work only when you loose the switch to
control forward and backward movement, or loose the handle.
Then the electric current will be cut off before the truck stops.
Press the red switch on the top of handle when the truck is
moving, the truck will move rest-direction immediately.
PPI-90 electric locomotive are equipped with powerful tilt resist
system. There is one safe wheel on both sides of the drive wheel.

When the truck inclines to 1.5°(5mm), the safe wheel will
reach the ground. Then 900N reacting force is acted on the truck
(having regulated in factory). The gradient rises as the reacting
force increases until the gradient reaches 5°30’ (25mm), the safe
bush locks the truck (the reacting force reaches 2000N) and the
safe wheel provides the rigid support for the truck.

4) Hydraulic part

Adopted the American Fenner Hydraulic System, the work

ressure is 16Mpa. The hydraulic system is formed in entirety and

p
it is compact in structure and reliable in quality and durable. The
cylinder adopts the piston rod type, with treatment chromate on
the surface of piston rod. The cylinder is wear-resisting and
stainless. The hydraulic system connects the cylinder with
high-pressure hose to make a sealed cycle.

1. The hydraulic cycle: oil pump =>combined valve => manual

Vestil Manufacturing Corp.

change valve => cylinder => oil-tank.

2. The pressure regulation: The truck has been regulated by
specialist. Please do not adjust the truck unless it is necessary. If
necessary, regulate the truck with full load by the specialists or
experts.

3.

The hydraulic oil: If there is no enough oil in the oil-tank (the

truck cannot elevate and it will make a noise), fill the oil-tank
with hydraulic oil to the 4/5 capacity. It is better to used HL-46
hydraulic specific oil, or you can use HV-32 oil instead.

5) Electrification system
Input voltage: DC-24V (2x12V)260Ah

Drive motor: DC-24V 2500RPM 4.5NM
Hydraulic motor: DC-24V 2400RPM
Moving motor and hydraulic motor adopt DC-24V motors. It is
easy to operate, reliable and safe without pollution. Electrification
serves as the power to lifting or moving.

Electrification system consists of charger => battery => Dc

motor.

Battery serves power supply at work. When you want to charge
the battery, pull the plug out of the plug base in truck, and connect
the plug with the charger and connect the charger to 220V/50HZ-AC
mains. When the charge finishes, disconnect the AC mains before
disconnect the battery and the charger.

) Safe operation

6

1. Check the truck’ condition before you operate it. The truck must

be operated in well state.

2. Do not operate this truck unless you are trained and authorized.

The driver must observe the safe operation regulations.

3. Do not operate the truck with riding on it. Never place any part

of your body under the forks or near the moving part when the
forks have been lifted.

5

4. Keep the well sight and enough range to other people or

800-348-0868

mechanism. When handing long high and wide load, avoiding to
affect your sight, you must forego the truck, move carefully.

5. Reduce the speed when other people or truck is nearing. If you

want to forerun the other truck or bring to somebody’s attention,
you can use the electric bell.

6. Pay attention to control your truck, use urgent brake and

repeated start and speedy turn as few as possible in order to
lessen the damage of vehicle and accidental injuries of persons.

7. Before you start the truck, ensure your freight stable. Place the

forks to the lowest, 150~400mm is the best distance to the
ground.

8. Do not overload the truck, otherwise, it will add to the truck’s

wastage and easy to cause accident.

9. Moving on slopes, you must observe the instruction stated below:

Do not hand the unstable or loosely stacked loads. Keep the
forks lowest and travel slowly and with caution. The same as
unload travels. You must not always turn your truck on the
slopes.

10. If there are some faults in your truck, you must repair it in time

by the specialist or expert. Don’t operate the damaged or faulty
truck. Our company provides the specialized maintenance.

7) Battery’s and Charger’s usage and conservation

1. B

2. Charging should be operated in ventilation and non-flammable

3. The charging voltage must be limited within 13.8 ~ 14.2.

attery must be placed stable on rack avoiding to short circuit.
Ensure that the polarities of the battery are connected correctly
and with good contact. Apply some geoline to pretend the
interface from corrosion.

surrounding. Keep battery and charger away from spark, high
temperature and moistness. You must provide enough
operating space for charging, otherwise, it would be result in
overheat.

6

Always inadequate charge will result in transformation

sulphuric acid into sulphate and this will easily to shorten the
life span of battery.

4. You should charge the battery before you conserve it for a long

time. The same you should do if you want to use a battery that
had been conserved for a long time.

5. Battery must be conserved in ventilation and drying

surrounding. Keep it out of sun and keep the temperature
lower than 40 degrees.

6. Battery charger is equipped steering computer monitor and

over-current protector, all the charging status need not manual
controlling. When the capacity of battery is fully charged, the
charger will cut off output automatically.

7. Before charging the battery, be sure that the DC output
charging cables of the charger are connected correctly and
reliably to the battery, take care to connect the correct cables
respectively to the terminals (+) and (-) of the battery.

List of enclosures

1. a Chinese-English instruction manual of charger

2. a electrification principle drawing

3. a electric wire for charger output

5. a instruction manual for walking stacker

5. a customer register

6. a certificate of inspection

7. a guarantee certificate

Note: * After the truck has been sold, our company provides the

free maintenance in three years and the lifelong maintenance.
