Foton Revo FR360 excavator new appearance BMW show

During the bauma china 2008 exhibition, Foton Lovol launched the 21 ton, 23 ton, and 25 ton medium-sized excavators and launched the new FR360-7 large and medium-sized excavator, which was highly concerned by the exhibition.

In the past two years, the national excavator brand represented by Foton Lovol Heavy Industry has achieved rapid development and has achieved remarkable results, which has aroused widespread concern in the industry. Since entering the excavator industry in 2005, Foton Lovol has been sticking to the high-end route. They are strengthening their technical cooperation with international construction machinery giants, and while they are in line with international standards, they are paying more attention to the absorption and digestion of advanced technologies. In terms of manpower, material resources, and financial resources, the company has conducted in-depth research on the core technologies of excavators such as engine support, hydraulics, and electric control, gradually formed its own technical route, and continuously developed excavator products that are more suitable for Chinese users.

While Foton Lovol achieved rapid breakthroughs in the small digging market, it did not satisfy the status quo. Instead, it quickly advanced to the increasingly fierce market of medium and large digging. After the 13-ton product was put into mass production and 21-ton products were successively trial-produced successfully, It also completed the development of 23 tons, 25 tons and 36 tons of large and medium-duty excavators. The engine uses the Isuzu engine and the emission meets Euro III standards. It has various operating modes, security alarm systems, GPS global positioning, data transmission, and fault self-diagnosis. Function, to ensure that the machine has a high degree of security and work reliability. What is more worth mentioning is that Foton Lovol successfully used the international advanced positive flow hydraulic control system for the first time in the development of this product.
At this stage, the domestic medium-sized hydraulic excavators generally use negative flow control systems. The features of the negative flow control system are: The engine power can be fully utilized, and the flow of the pump is automatically adjusted according to the size of the load, and the change of the load is automatically adapted to reduce the uselessness. Hydraulic loss, reduce system heating, save energy and reduce consumption. However, there are disadvantages such as large flow fluctuations, long response time, and poor maneuverability. With the rapid development of electromechanical and hydraulic integration technology, the forward flow energy-saving control technology for excavators has matured. Its technical features are: the pressure of the main pump is proportional to the output pressure of the pilot operating handle, realizing the real-time control of the variable pump, ie, on-demand For oil supply, the system has less flow and energy loss during neutral or micro operation. Relative to the negative flow control system, the positive flow control system has the advantages of variable response time, small flow fluctuations, good operability, can increase work efficiency by 9%, saving about 12%, while overcoming the pressure compensation Energy loss, system reliability is higher.
The successful application of the positive flow hydraulic control system symbolizes the breakthrough in the high-end technology of large and medium-sized excavators of Levo excavators, and has the strength to compete with foreign high-end brands. The rapid development of the Revox excavators tells us that in order for national brands to achieve rapid development in the excavator industry where foreign brands are strong, the following points must be firmly established:
1. Enhance independent R&D capabilities, pay attention to the application, research and development of hydraulic and electronic control technologies, fully grasp the core technology of excavation, adhere to high-end routes, develop high-performance, high-reliability, and cost-effective products to meet the long-term needs of the market.
2. Pay attention to the investigation and research of the market, paying particular attention to changes in the user's mental needs caused by changes in consumer demand and changes in the user's operating environment, and fully embody the user's needs in product design, and develop differentiated and truly adapted current users. Personalized demand products.
3. Pay attention to the research and application of the excavator's core technology, achieve technological breakthroughs, ensure technological advancement and continuous technological innovation, and truly contribute to the Chinese people.
