What are the problems that are easily overlooked in engineering auto parts?

Many car owners tend to ignore some problems on the parts of the construction vehicle when they purchase the parts of the construction vehicle. For example, some parts of the construction vehicle are worn out, so they are prone to failures when they are in use. Inspection, maintenance and replacement of accessories. Regarding the selection skills of truck-mounted crane auto parts, today’s truck-mounted crane is briefly introduced.

When buying accessories for on-board crane construction vehicles, you should choose some reputable and better service accessories distribution units to buy, and you should pay attention to choosing a business as you would when buying a complete vehicle. There is also the need to use scientific names as much as possible, and the names of accessories that everyone can understand to buy accessories. In addition, it is necessary to recognize the brand of the accessories, pay attention to grasp the information, buy the recent famous accessories, and ask for the invoice for the purchased accessories, and indicate the detailed origin of the parts. In order to protect our legitimate rights and interests, we try our best to avoid buying some fake and shoddy accessories.

How to test the handling performance of the truck-mounted crane (Dongfeng truck-mounted crane) special vehicle? In fact, this is very simple. The handling performance of the truck-mounted crane can be easily detected from the following three aspects:

One of the detections: the steering of the truck-mounted crane: it is mainly to check whether the direction of the greening sprinkler is sensitive, accurate and stable. The method is, in the process of driving, shake the steering wheel gently and slightly to see if the front of the car shakes with the steering wheel, and the speed of the response. Of course, the response is very sensitive. If there is no response, That means the direction of the car is loose. When driving at high speed, check whether the steering wheel is stable. If you need to hold both hands tightly to drive with confidence, it means that the stability is relatively poor.

The second test: the braking of the truck-mounted crane: mainly feel whether the brake is sensitive, whether the braking response can be consistent with the force of the brake pedal, and whether the vehicle is stable when braking. You can try to step on the brake pedal with different strengths to see if the brake can be lightly stepped on, and whether it can be stopped quickly with a heavy step, without lag or deviation.

The third test: the speed change of the truck-mounted crane: For manual gear vehicles, the transmission is a frequently used operating component. In the test drive, push the shift lever into each gear in sequence, and feel whether the shift lever enters and exits each gear smoothly without blocking feeling, and whether the position of each gear is clear and not easy to hang wrongly。
