Each small part on a forklift is irreplaceable in its function. Today, let's discuss the effect of the rear work lights on a forklift. Generally, the rear indicator lights on a forklift consist of red brake lights, red taillights, yellow turn signals, and white reverse lights. To meet the aesthetic requirements of the vehicle, the SF160 heavy-duty forklift's rear indicator lights are available only in red and yellow, featuring red brake and taillights, and yellow turn signals, with the white reverse light omitted.
The reversing indicator function is achieved by the two rear working lights located at the back of the cabin, which serve as reverse lights during the day and tail lights at night. This design is based on the fact that this heavy-duty forklift is commonly used for port container handling. During daylight operations, the rear working lights are not used for illumination, but instead, they are utilized as reverse lights. At night, when port lighting is dim, it is necessary to switch on both the front and rear working lights to ensure the operation is completed normally.
During forklift daytime operations, the form change switch 1 should be set to the daytime position (i.e., terminals 1 and 5 closed). When reversing, the transmission control unit 2 sends a low voltage signal to the reversing relay coil 3. The main contact of the reversing relay 3 closes (i.e., terminals 30 and 87 closed). Current flows from the positive terminal of battery 4, through fuse 5, the main contact of the reversing relay 3, the contacts of the form change switch 1 (terminals 1 and 5), to the rear work lights 6, 7, and back to the negative terminal of battery 4, completing the circuit. Both rear work lights 6, 7 illuminate simultaneously, and the reversing buzzer 8 sounds.
When operating forklifts at night, the form change switch 1 should be set to the night position (i.e., contacts 7 and 5 closed), and simultaneously, the work light switch 9 should be turned on. At this point, the current flows from the positive pole of battery 4, through fuse 10, the contacts (1 and 5) of the work light switch 9, the contacts (7 and 5) of the form change switch 1, to the rear work lights 6 and 7, and then back to the negative pole of battery 4, completing the circuit. At this moment, regardless of whether the forklift is reversing, the two rear work lights 6 and 7 remain constantly illuminated to provide lighting.
If the work light switch 9 is not closed at night, both rear work lights 6 and 7 will not respond when the forklift is reversing, only the reverse horn 8 will beep. If the night/day switch 1 is in the daytime position (i.e., 1 and 5 are closed), the rear work lights 6 and 7 will only illuminate when reversing.
Additionally, to facilitate drivers in identifying the operational status of switches during night shifts, indicator lights are installed on both the work light switch 9 and the form conversion switch 1. When the combination switch 11 for headlights is set to the indicator position, both the front and rear indicator lights of the forklift are illuminated, and the indicator lights on the work light switch 9 and the form conversion switch 1 remain constantly lit.
