GROUP 3 ELECTRIC COMPONENTS
1. FUNCTIONS OF BATTERY FORKLIFT TRUCK AND ELECTRIC COMPONENTS.
The major functions of forklift truck can be divided into DRIVING FUNCTION and LOADING &
UNLOADING FUNCTION.
All the components that work DRIVING and LOADING & UNLOADING functions are driven by AC
MOTORS. And as the BATTERY works as power source of these motors, a charging device is
needed.
To drive the fork lift truck, a DRIVING CONTROL SYSTEM and some electric components such as
direction change lever(forward/reverse section switch) and accelerator are required to select the
driving direction and to control the speed of driving motor.
The CONTROL SYSTEM includes some protective circuits that protect the equipment and
components from malfunctioning.
A MONITORING SYSTEM is installed in the monitor panel, which monitors the equipment and
working condition, and let the operator take proper action. For the monitoring system, there are many
sensors such as current sensors, hydraulic pressure sensors, and temperature sensors. The
HYUNDAI Battery forklift trucks are equipped with the most advanced DRIVING CONTROL SYSTEM
currently available world-widely. The operator friendliness features enable him to set the truck
conditions properly according to each working circumstance easily on his seat, and the SELF-
DIAGNOSTIC function displays current status of truck in working.
