Crane cab abnormal response to what should be checked, now our small edition for you to introduce how to do if the crane cab abnormal sound. Now let's get together with our little editor. We should do this when the crane cab has abnormal noise.

Is the inspection possible for these reasons?

The steel plate problem, the crane cab under the steel plate friction, this situation is not a big problem, may be due to the failure to run-in, this does not affect the driving;

When the crane cab and chassis are occluded, the lining will not ring.

Check the crane cab to avoid shock. Look at the shockproof glue of the shock absorber.

Crane cab paint body should be how to protect, naked eyes can see the car paint black, white, matte and other phenomena, oxidation can be seriously grinded and polished. If you don't give the paint some necessary care, the cab metal paint may produce a very fine crack, it will from time to time soak the paint, until "break through" the whole paint layer, this phenomenon is called "crack".

Under the sun's ultraviolet rays, the film evaporates oil into the air from time to time to maintain itself. A long time will lose the oil content of the paint. The brightness and depth of the paint surface are greatly reduced, making the paint surface gradually white and forming oxide layer. Sometimes, because of the quality of the paint, cracks can also occur. More wax can be used to reduce the cracking of paint.

Stop checking the cab regularly to find out the potential faults and prevent them from happening. At the same time, you will understand the habit of loving the car more and adjust it to the best condition. Check oil and brake oil, such as shortage, and replenish it in time.

The crane cab can check whether the chassis has leakage or leakage. Check tyre pressure, tread wear and nut loosening. If the driver feels that there is a phenomenon of deviation or swing, to the maintenance station to do four-wheel alignment or dynamic balance check. Check whether the fan belt is damaged or broken, and adjust the tightness of the belt. Check the wiring status of the whole car wiring harness, such as cracking, loosening, and poor contact. Note that the coolant should not be replaced with clean water.

The cab cab has a strong electrostatic layer due to friction during driving. Static electricity has a strong adsorption capacity for dust, oil and chemical dust. A hard traffic film will be formed over a long period of time. It is easy to cause oxidation corrosion of the paint surface and can be used for grinding and polishing.

Crack: If you don't give the paint some necessary care, the metal paint may produce a very fine crack, it will continue to penetrate the paint until it "breaks through" the entire paint layer, this phenomenon is called "crack". Sometimes, because of the quality of the paint, cracks can also occur. The wax cracking can be reduced by waxing and so on. Regular check on the cab crane, timely detection of potential faults, prevention in the future, but also to make you more aware of the habit of car love, to adjust it to the best condition.
