A reliable dump truck must have these characteristics

Nov. 26, 2020

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 whole vehicle is matched with reasonable light weight. The dump industry also follows the principle of light trucks and more goods. However, considering the special nature of the work of dump trucks, light weight must not be blindly reduced.

In addition to the use of high-strength material for the body structure, the application of aluminum alloy accessories is also a good choice, such as aluminum alloy wheels, tool boxes, outriggers, mudguards, etc. The overall weight loss will 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.
