、Basic structure and principle
.1 Basic structure
With the battery as the power source, the stacker uses electrical and

. Operating principle
. .1 Running system
The unit’s running system is powered by the battery. (The AC Motor gear
reduces high speed low torque into low speed high torque, in the end by
the driving wheel to perform efficiently. The speed of the driving is done by
variable frequency control of motor speed.)

The gear box has been supplied with enough gear lubricating oil at the
factory. Replace gear lubricating oil every 1000 hours under normal
circumstances and use.
During normal operations, if sounds are heard from the gear box,
immediately stop the unit and determine whether bearing damage or
other gear problems are evident.
. . Steering system
The movements of the Counter Balanced Stacker are controlled by the
steering wheel and operating commands located on the handle bar.

. .4 Braking system
Braking performance depends on road conditions and vehicle load。
The brakes can be activated as follows：
1 Move the Fahrschalter ( ) to position ‘0’(middle position). The
vehicle will brake until it stops.
2 Move the Fahrschalter ( ) in the opposite direction. The vehicle
will brake until it begins to move in the opposite direction.
3 Vehicle braking, if the handle is upright or completely downright
the unit will not function.
4Pushing the belly safety switch (4) may prevent the operator
from being pinned from behind.
. .5 Operating system
The stacker’s main function is tray or cargo loading and unloading,
stacking and short-distance transport operations.
The pallet fork is maneuvered into the pallet. The carriage is moved up
and down inside the stacker door frame by driving chain (see 2.2. :
function 2: Lifting and lowering switch) to lift goods off of the ground or to

deposit them on shelves. The lifting chain and will move the whole inner
frame by lifting the oil cylinder telescopic to activate Stacking process is
implemented by the control operation of oil cylinder telescopic.
.3 Electrical principle
.3.1 Electrical principle
The unit’s electrical system provides the movement and function
operations. The stacker is equipped with the communication electronic
assembly CURTIS12 2E and CURTIS12 0E (Made in America). The
instrument includes the functions of battery indicator, working time
display and voltage protection. When the battery power is too low, the
electricity meter will cut off the oil pump motor and the start control
circuit. The Counter Balanced Stacker will only be able to walk and cannot
lift/lower the forks. If this occurs, charge the battery immediately.
The oil pump motor is not designed for continuous operation over a long
period of time. Lifting action should be limited rather than continuous,
otherwise the motor will overheat and could become damaged.
Note: When the Counter Balanced Stacker has been in use over a long
period of time, the oil pump motor may eventually fail. When this happens,
immediately stop the unit, disconnect the power supply (which will make
the oil pump motor stop running) and replace the starter.
