Who has the history of the development of dump trucks 5

In recent years, domestic dump trucks have also begun to focus on lightweight. However, for cost and technical considerations, domestic dump trucks are still made of ordinary steel and steel plates as the main materials, and in order to pursue overload, the box is usually made relatively large, such as 8 4 models have a compartment that is more than 8 meters long, and 6 4 models do 68 meters, the thickness of the carriage is mostly the bottom 10 sides of 8.

In the field of traction semi-trailer dump trucks, domestic products are even rarer. A small number of enterprises have developed overturned and backward overturned monolithic semi-trailer dump trucks, but due to the backward semi-trailer technology and large vehicle length, the application range is greatly limited.

At present, domestic truck manufacturers have begun to pay attention to the potential of product modification. It is worth mentioning that Dongfeng's Tianlong and Tianjin, these two cars are relatively close to European trucks in chassis design, and adopt a standard hole design, which is convenient for modification enterprises. However, for some dump trucks used for medium and long-distance earthwork transportation, in recent years, with the overload of governance, the rapid development of domestic heavy-duty vehicles, in terms of models and product structure have undergone tremendous changes.

In this process, dump trucks have also been developed, especially in the type, structure, vehicle materials have undergone earth-shaking changes, there are many new varieties, such as special mining dump trucks, municipal earthwork trucks, large-capacity coal dump trucks and vehicles with bad road conditions. It is worth noting that these products have gradually introduced European technical concepts, from prototype design to the application of structures and materials, and have begun to focus on learning from the mature experience of Europe, and combined with the actual domestic market, showing some of their own characteristics.

The degree of standardization of European vehicles is high, and many companies have adopted the modular design concept of assembly, and some integrated parts such as guardrails, ladders, spare tire racks, bumper assemblies, etc. are provided by specialized parts manufacturers. These standardized and modular components are unique and aesthetically pleasing. Vehicle manufacturers use bolts and other detachable assembly methods to assemble these integrated parts with the whole vehicle, which greatly improves production efficiency and facilitates maintenance.

Dump trucks make money as long as they have a job! It's better in Suzhou, jj less, and a lot of them are boss bags! If you don't live, the insurance will be four or five thousand a year...

A dump truck is a vehicle that dismantles and unloads goods by hydraulic or mechanical lifting. It is also known as a volcanic fiber bucket truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device and other components.

The structure of the engine, chassis and cab is the same as that of a regular truck. The carriage can be tilted backwards or sideways, and the movement of the piston rod is controlled by the manipulation system, and the backward tilt is more common, and the piston rod is pushed to tip the carriage. A handful of two-way tipping.

The high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and the front end of the compartment has a cab safety protection plate. The engine drives the hydraulic pump through the transmission and the power take-off device, and the hydraulic tipping mechanism of the carriage is composed of a fuel tank, a hydraulic pump, a distribution valve, a lifting hydraulic cylinder, a control valve and an oil pipe. The engine drives the hydraulic pump through the transmission and power take-off device, and the high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and oil pipe, and pushes the piston rod to overturn the cabin.

Rear tipping is more common, and the piston rod movement is controlled by the maneuvering system, which can stop the carriage in any desired tilt position. The carriage uses its own gravity and hydraulic control to reset.

The main technical parameter of a dump truck is the loading weight, and the loading volume is indicated. New cars or overhauled factory cars must be put into trial operation to make the lifting process of the carriage smooth and non-stringing. When using, each part should be correctly selected according to the regulations, which greatly saves the unloading time and labor, pays attention to the lubrication cycle, and the lifting mechanism changes the oil strictly on schedule.

Shipment according to the rated loading capacity, overloading is strictly prohibited.

According to the chassis carrying capacity, it can be divided into light truck series dumping, medium ton series dumping and large tonnage series dumping;

According to the drive form, it can be divided into different series of models such as single-axle dump, double-axle dump, front four and eight dump, front four and ten back;

According to the different unloading hydraulic lifting mechanism, it can be divided into single top dump and double top dump.
