Operating Principle; Running System; Steering System; Brake Structure And Brake Schematic Diagram - EKKO EP30A Manual

5.1 Running system

The truck is powered by a battery, and the DC power is converted into AC power by a
frequency conversion system, which is realized by controlling the AC motor on the driving
wheels. The AC motor converts high-speed and low-torque into low-speed and high-torque
through a gear reduction box, and finally the drive wheels perform the action. The speed of
walking is achieved through frequency conversion control of the motor speed, which is
controlled by the accelerator.
Gear box in the factory has been posited enough gear lubricating oil. And please change the
gear lubricating oil every 1000 hours under normal circumstances.
If you hear abnormal sound from gear box when using, please stop and check immediately. If
there are bearing failure or some problem in gear, please replace and repair them.

5.2Steering system

The steering of the moving car is driven by the handle lever through the handle lever to
drive t motor to achieve 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 accelerator switch (2) to "0" position or release the switch to make truck brake
⚫
until it stops.
With the accelerator 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 start braking until it stops.
Emergency Reverse button (3) can prevent the operator will be squeezed, when the
⚫
truck is facing an obstacle in (' Fw) direction .The body touch Emergency reverse
button and the truck decelerates or starts to move to (BW) for a distance and then
stops .If the handle is in the operating area and the truck is not moving, please consider
that this button is still working.
