Electrical System
OVERVIEW
The electrical system in this model series is a single-
line electrical system that utilizes anode bonding in the
truck’s electrical circuitry to ensure that the forklift truck
works properly in various conditions. The electrical
equipment is composed of following systems:
Power supply system
The power supply system consists of battery,
alternator, charging indicator light and other
components. It supplies power to the electric
equipment of the truck. The battery provides power
prior to starting the forklift. The alternator provides
power when the forklift runs, and at the same time
charges the battery. The charging indicator light is
used to display the charging status.
Starting system
The starting system is composed of glow plug (diesel
truck only), key switch, neutral switch, and starter
lamp. The function of the starting system is to start the
engine. After the key switch is turned on, the glow plug
heats up. The starting system has neutral protection
function; the truck will only start if the shift lever is at
the neutral position.
Ignition system (ICE forklift truck)
Gasoline equipped forklifts do not have a preheating
components as diesel forklift do. They have spark
plugs, and on some ICE engines a distributor and
spark plug wires are present for the ignition system to
function.
Preheating system (diesel forklift truck)
The preheating system mainly consists of preheating
plug (glow plug), preheating relay and time relay. The
preheating time is set to 10-13seconds, but can be
adjusted through time relay. Diesel with ECU electric
control system is available. A temperature sensor is
equipped to detect whether the current temperature
needs to be preheated to increase the service life of
components.
