5.Operating principle
5.1Running system
The truck is powered b a batter , which is realized b controlling the AC motor on the drive
wheel.The speed of walking is realized b frequenc conversion control motor speed, which
is controlled b the accelerator.
5.2Steering system
The steering of the moving car is driven b 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 directl 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 truc brakes.If the
handle is released, the handle automaticall moves to the upper braking area (' B ') and
the truc start bra ing until it stops.
Emergency Reverse button (4) can prevent the operator will be squeezed, when the truc
is facing an obstacle in (' Fw) direction .The bod touch Emergency reverse button and
the truc deceleates or starts to move to (BW) for a distance and then stops .If the handle is
in the operating area and the truc is not moving, please consider that this button is still
working.

5.3.2Braking operation principle
：
As follow picture ： The brake constitute b magnetic oke 6 ,magnet exciting coil,7 , the
spring 2, the bra e disc 5,the armature 1, the gear sleeve 4, the mounting screw 3,And so
on .The bra e 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 oke assembl 6, and the armature 1 is disengaged (released)
from the brake disc 5.At this time, the motor drive shaft is normall 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.
Brake schematic
5.4 Operating System
The main working bod of a moving truck is the fork, which relies on a fork to carr the
pallet or cargo for transport and short distance transportation.The expansion of the c linder
is realized b the control of the operating handle, and the pressure oil is provided b the
pumping station.
5.5 Electric System
The electrical s stem includes walking and operation control.The truck use DC electric
control assembl .

12
The meter has a batter indicator.When the batter power is too low, the electric meter will
cut off the starting control line of the oil pump motor. The truck can onl walk and can’t lift
the fork,, and the prompt should be charged immediatel .
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 continuousl
carr 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 ma
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 immediatel stop at this moment, to cut off
the power suppl (unplug batter plug-in), make the oil pump motor stop running, and
promptl replace the starter.
5.6 Hydraulic principle
The oil pump motor drives the gear pump to provide h draulic power,lifting oil c linder is
responsible of fork’s lifting and lowering,The control of the lift oil road is controlled b the
buttons on the operating handle,The lifting action is controlled b a single action oil circuit
on the valve block.This model of the h draulic s stem pressure can onl be adjusted on the
valve block, has been debugging good, before the go out after the leaving our factory,If not
the our compan after-sales personnel or professional maintenance personnel are strictl
forbidden to adjust themselves, so as to avoid safet accident.

8.How to assemble the operating handle of pallet truck
EP15SLI/EP18SLI with Manual lowering
Step 1.First take out the 2pcs elastic c lindrical pins (1) on both sides of the
c linder , and then take out the rotating shaft (2)
Step 2 .Install the handle assembl (5) and rotating shaft (2) to the oil
c linder.And then fixed the rotation shaft (2)、
