The excavator wiper does not work


Excavator wiper
The frequency of the wiper of the excavator is not as high as that of the car. On the one hand, the visual field of the excavator is better, the light rain can't stop the driver's sight. On the other hand, if the weather is very bad, the excavator will be safe for the sake of safety. Direct work.
Of course, if the safety factor of the construction conditions is high, and it happens to meet the heavy rain and other weather, it is still necessary to catch up with the project. At this time, the wiper will be of great use! But how the idle wiper hasn't responded to it!
Fault phenomenon
The owner reacts, because the rainy season has to catch up with the construction as usual, so the owner presses the wiper and the water spray switch, but the monitor does not have the wiper and water spray symbol, because the excavator wiper has a low opening frequency, so the owner can not determine where it is. broken.
Cause Analysis
▊ In order to prevent the wiper from being damaged by brushing in the large windshield pull-up state, a safety switch is usually installed in the left front of the cab.
▊If the windshield is pulled up and the safety switch is closed, the wiper controller will close the wiper system and the wiper will not move.
The excavator of the main Engine is the Kobelco eight-machine type. The six-type machine also has this switch, but it is installed behind the cab.
▊ Because the switch is very concealed, it can not cause everyone's attention and ignore it. It will even lead the maintenance personnel and the owner's maintenance ideas to other parts of the wiper system, which will bring great repairs to the maintenance.
Processing method
▊Check if the big windshield is locked. The big windshield needs to be pushed forward after it is put down to lock it.
▊Check if the safety switch is disconnected after the large windshield locks.
▊If the safety switch is not disconnected, adjust the pusher next to the safety switch until the safety switch can be successfully disconnected. The problem will be solved!
to sum up:
There are tens of thousands of parts on the excavator, especially the small parts such as the wiper safety switch. The frequency of opening is very low, and even if it is not used for a long time, the owner will inadvertently ignore it. An oolong fault.
Of course, this problem also hopes to arouse the resonance of your friends. Many times, it is not enough to have good driving skills. Knowing the excavator and familiarizing with the excavator can make you a real old driver! In this way, in the judgment of many simple faults and oolong faults, it can be faster and more accurate!
