Using the truck after work lights

Usually after the truck lights from red brake lights, showing the wide red lights, yellow and white reverse lights turn signals components. In order to meet the aesthetic requirements of the vehicle appearance, Hill pushed production SF160 type reloading the truck only after lights red, yellow two kinds of colors, with only the red brake lights, showing the wide red and yellow lights turn signals, but not set white reverse lights.

Its reverse indicator lights work by two after the cab after the realization that the work lights down lights during the day, night after backlight. This design based on the reload truck used for container handling port. After the truck during the day and do a job of work lighting, rear work lights just as down lights use. Port of relatively dim light at night, when the High Mast Diesel Forklift job must be front and rear work lights turn on, can ensure the safety of operations.
After the truck working lights control principle as shown in the figure, which is mainly composed of a mode switch, transmission electronic control unit 2, reversing relay 3, 4 batteries, fuses (5, 10), after working lights (6,7 ), reversing buzzer 8, work lights switch 9, headlight combination switch 11 and other components. It works as follows:

During the day when the High Mast Diesel Forklift operations, a mode switch should be placed in the daytime block (ie, closed 1,5). When reversing, the transmission electronic control unit 2 issued a low level to reverse the relay coil 3, reversing relay energized 3 main contacts (ie, 30 and 87 closed). Current from the positive electrode of the battery 4, the fuse 5, reversing relay main contact 3 mode switch contacts 1 (1 and 5), to 6,7 after work lights, back to the negative battery 4, to form a loop. While two rear work lights lit 6,7, reversing buzzer beeps 8 turns.

Lpg Gas Forklift Truck night operations, should be in nighttime mode switch a block (ie, 7 and 5 closed), while the work lamp switch 9 is closed. At this point, the current from the battery positive 4 through fuse 10, work lights switch contacts 9 (1 and 5), a mode switch contacts (7 and 5), to the rear work lights after 6,7, back the negative electrode to the battery 4, to form a loop. At this point, whether the truck is reversing, work lights are lit two after 6,7, to play the role of lighting.

If you do not have to work at night lamp switch 9 is closed, when the truck reversing two rear work lights 6,7 no response, only 8 reverse buzzer sounds. If a night mode switch is in the daytime block (ie, 1 and 5 is closed), the rear work lights 6,7 only when reversing lights.

In addition, in order to facilitate the work of the driver during the night to see the working status of each switch in the work lamp switch 9 and mode conversion has an indicator light on the switch. When the headlight combination switch 11 is in showing the wide gear, before the truck, showing the wide rear lights are lit, while working lights switch 9 and a mode change switch on the lights is also lit.
