Since the second half of last year, the demand for dump semi-trailers has increased sharply. Before buying a car, many new car owners are faced with many manufacturers, brands, configurations, and product explanations that are different from salespersons. They may eventually be dazzled and have no way to start, so what is a good one? What are the good characteristics of the dump truck? Now let’s count them down.
First of all, the structure of the vehicle design should be reasonable, and the center of gravity of the chassis should be as low as possible. According to the load of the dump semi-trailer, the type of cargo, the road conditions and the driver's driving habits, the system should be planned and designed to meet different usage requirements.
Secondly, the materials used should be real. The seemingly identical steels are actually divided into high-strength steel, manganese steel, and ordinary carbon steel. Among them, the high-strength steel is divided into 700, 900, and 980 models. Its durability and strength are gradually improved with the increase of the label. The weight can be gradually reduced, but the cost will also increase.
Once again, the vehicle processing technology has to pass, but now with the popularization of mechanical automation, many factories have realized basic automation in the process of vehicle processing, such as cutting and welding, and the production process has generally been greatly improved.
In addition, after welding and forming, it is necessary to perform processes such as surface sandblasting and rust removal, so as to better increase the adhesion of the paint.
The spraying of the paint should be uniform and the coverage should be comprehensive. The paint is divided into alkyd paint and high-end polyurethane paint. Considering the structural characteristics of semi-trailers, the spraying method is mostly a semi-automatic method combining manual and machine. Many manufacturers have also begun to try in recent years. Emerging electrophoretic coating.
The entire vehicle is reasonably lightweight and matched. The dump industry also follows the principle of lighter trucks and more goods, but considering the particularity of the work nature of dump trucks, it must not be blindly lightweight.
In addition to the use of high-strength material body structure, the application of aluminum alloy accessories is also a good choice, such as aluminum alloy wheels, tool boxes, legs, mudguards, etc. The overall weight loss will also be about 400 kg.
In addition, the quality of key parts must be reliable, such as axles, domestic axles, domestic joint venture brand axles, and imported axles. There is a big difference in price. In terms of quality, practice has proved that it is certainly true that you get what you pay for.
The lifting hydraulic system must be stable, the oil circuit design must be reasonable, and the cylinder lift must be synchronized. The hydraulic system is the power source for dump truck dumping and unloading. It is mainly composed of pumps, valve groups, fuel tanks, pipelines, cylinders, etc. Original composition, the hydraulic system must operate stably to ensure the normal discharge of materials.
In addition, the installed tires need to have a national three-guarantee commitment. This model generally matches 12.00 tubeless tires. High-quality tires are an important guarantee for driving safety. Only brand-protected tires can better protect driving safety.
Dump semi-trailers are not a new thing for a long time. It is recommended that new car owners consult with old car owners, because many old car owners have their own experience in the process of using them, and they have their own opinions on different manufacturers and various accessories. Choose some good word-of-mouth, cost-effective ones, maybe the cost may be higher, but once put into long-term use, after all, the reliable operation of semi-trailers is the prerequisite for car owners to obtain stable income.
