As the fundamental equipment for building engineering and resource transportation, dump trucks have turned out to be indispensable vehicles for the current society. With their outstanding load-carrying overall performance and handy loading and unloading mechanism, dump trucks play an increasingly vital role. Their precise structure and multivariate performance parameters warrant systematic research.
I. Precise structural system
Dump trucks’ structure represents the essence of industrial practice. The chassis mechanism, the “skeleton” of the whole truck, consists of high-strength metal alloys and is equipped with high-usage suspension systems. It can keep stable work even on irregular roads under complete load. The energy system is as essential as the “heart”: diesel power is effective and booming, and electric drive is clean and efficient. Both can adaptively fulfill the load requirements of unique working conditions.
The lifting mechanism and cargo compartment constitute the primary functional modules of the dump truck. For those instances of ore transportation, a wear-resistant steel plate cargo compartment can be adopted to successfully resist the friction loss of strong particles. The hydraulic lifting system coordinated via hydraulic pumps, hydraulic cylinders, and manipulator valves is capable of obtaining the tilting movement of the cargo compartment within 30 seconds to attain full unloading. The smart elevator machine also offers an inbuilt automatic adaptive mechanism to variable loads and road conditions, in such a way as to ensure the same degree of security as efficiency.
II. Performance parameter analysis
The performance of distinctive models of dump vehicles differs greatly. Taking the SITRAK series as an example, the 324 kW (about 440 horsepower) diesel engine can ensure steady output even on uneven roads and gradients. Its front and rear axles are bolstered with heavy-duty type, with a remarkable load-carrying capacity. The 28 cubic meters of cargo space can elevate 75 tons of engineering materials, absolutely meeting the transportation needs of heavyweight construction materials. SITRAK’s maximum velocity for this model is 80 kilometers per hour, and the extraordinary tire configuration permits it to have excellent passability under complicated road conditions.
III. Economic selection strategy
Second-hand first-rate equipment is the best choice for price-conscious consumers. Professional second-hand construction machinery suppliers opt for budget-friendly automobiles for clients through reliable dump truck manufacturer supply channels and satisfactory checks. Each of our machines has to be subjected to more than 200 professional assessments on essential factors such as the motor, frame, cargo box, and hoisting device to ensure that protection risks are eliminated. We have set up an inspection crew of mechanical engineers and test experts. Currently, we have three bases in Tangshan and nine service stations all over the country to provide offerings for customers’ on-site vehicle inspection. Meanwhile, we have also developed foreign markets actively in recent years and successfully exported more than five hundred cars to the world, earning the faith of worldwide clients with flawless and fantastic services.
IV. Future development trends
With improvements in new energy technology and smart manipulation systems, the new generation of dump trucks is trending toward lightweight and electrification. In the future, vehicle-mounted smart terminals might also be capable of monitoring real-time working conditions and equipment load distribution, and carry out remote fault diagnosis through 5G technology.
Conclusion
From breakthroughs in character overall performance to the opening of a variety of utility scenarios, dump trucks have by no means halted the pace of technological innovation. As the mainstay of infrastructure transportation, this kind of engineering gear with power and wisdom will constantly be the cornerstone of global infrastructure construction, driving human development technology to a new height.
