5. Operating principle
5.1Running system
Stacker use battery as the power source through controlling DC motor on the
driving wheel to fulfill the function of walking, DC motor convert the high-speed
low torque to low speed high torque through gearbox, being implemented by
driving wheel. The speed of walking is controlled by accelerator .
In general, every 1000 hours change the lubricating oil in the gearbox.
During usage, if any noise coming from gearbox, please stop the stacker and
check, to judge whether bearing or gear have some problem.
5.2 Steering system
The steering of the stacker is driven by the operating handle through the
handlebar to drive the motor for steering.
5.3 Brake structure and brake schematic diagram.
Braking performance depends on road conditions and vehicle load conditions.
5.3.1The brake function can be activated by the following ways：
⚫Turn the travel switch (2) to "0" position or release the switch to make truck
brake until it stops.
⚫With the driving switch (2) moving directly from one driving direction to the
opposite direction, the vehicle regenerates the brake until it begins to move
in the opposite direction.
⚫The handle moves up and down to the braking area (' B ') and the truck
brakes. If the handle is released, the handle automatically moves to the upper
braking area (' B ') and the truck stops until it stops.
Emergency Reverse button (3) can prevent the operator will be squeezed, when
trucks are driven towards (' Fw) encounters an obstacle, body touch belly to slow
down or start to switch truck (' Bw) driven a short distance, then stop. If the
handle is in the operating area and the truck is not moving, please consider that
this is still working.

5.3.2Braking operation principle：
As follow picture：The brake constitute by magnetic yoke 6 ,magnet exciting
coil,7 , the spring 2, the brake disc 5,the armature 1, the gear sleeve 4, the
mounting screw 3,And so on .The brake is mounted on the end cap of the motor and
the mounting screw is adjusted to the specified air gap value.
When magnet exciting coil 7for brake on power，The coil generates a
magnetic field to to attract the armature 1 to the yoke assembly 6, and the
armature 1 is disengaged (released) from the brake disc 5.At this time, the motor
drive shaft is normally started and operated with the brake disc 5.When the
magnet exciting coil 7 is de-energized, the magnetic flux disappears, the armature
1 is released, and the spring 2 is pressed against the armature 1, and the friction
plate on the brake disc is pressed to generate frictional force for braking
purposes.

5.4 Operating System
The main working body of a moving truck is a cargo fork, which relies on a fork
to carry the pallet or cargo for transport and short distance transportation. The
expansion of the cylinder is realized by the control of the operating handle, and
the pressure oil is provided by the pumping station.
A descending valve is installed in the circuit of the lifting cylinder to slow down
the speed at which the fork falls, and the safety drop effect is achieved
5.5 Electric System
The electrical system includes walking and operation control. The truck use DC
electric control assembly.
The meter has a battery indicator. When the battery power is too low, the
electric meter will cut off the starting control line of the oil pump motor. The
moving truck can only walk without lifting the fork, and the stacker should be
charged immediately.
The motor of oil pump is the DC motor for 5 minutes, so the pump motor is not
suitable for long running. That is, the lifting movement should have time interval,
can not continuously carry on, otherwise would make the motor heating, even
burn.
Special note: when the truck is used for a long time, the starter of the oil pump
motor may fail, and it can't be broken after being sucked or closed. The latter is
not throw control handle, the oil pump motor is kept in the rotation, should
immediately stop at this moment, to cut off the power supply (unplug battery
plug-in), make the oil pump motor stop running, and promptly replace the
starter.
5.6 Hydraulic principle
The oil pump motor drives the gear pump to provide hydraulic power, lifting oil
cylinder is responsible of fork’s lifting and lowering, The control of the lift oil
road is controlled by the buttons on the operating handle, The lifting action is
controlled by a single action oil circuit on the valve block. This model of the
hydraulic system pressure can only be adjusted on the valve block, has been
debugging good, before they go out after they leave the our company after-sales
