5.Operating principle
5.1Running system
The truck is powered by a battery, which is realized by controlling the AC motor on the drive
wheel. The speed of walking is realized by frequency conversion control motor speed, which
is controlled by the accelerator.
5.2Steering system
The steering of the moving car is driven by the handle lever through the handle lever to
drive the drive motor to realize the 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 (4) can prevent the operator will be squeezed, when trucks

11
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 7 for 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.
5.5 Electric System
The electrical system includes walking and operation control. The truck use AC 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 prompt 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 personnel or professional maintenance personnel are strictly forbidden to adjust
themselves, so as to avoid safety accident.
