① Develop multi-type, multi-functional, high-quality and high-efficiency excavators. In foreign countries, even mini excavators with bucket capacity of only 0.01m³ have been developed . The functions of forward shovel and backhoe can not meet the needs of the project at all, so there are lifting, grab, flat bucket, loading bucket, harrow, breaker, twist drill, electromagnetic suction cup, vibrator, bulldozing Board, impact shovel, container fork, aerial work stand, winch, dragline ... How many have you used? There are even special excavators, low specific pressure, low noise, underwater special, amphibious and so on.
② Rapidly develop all-hydraulic excavators, and continuously improve and innovate control methods, so that the excavator develops from simple lever operation to hydraulic operation, pneumatic operation, hydraulic servo operation and electrical control, radio remote control, and electronic computer integrated program control. With the development of 5G, "remote control" may become a major change in the excavator industry.
③ Pay attention to the adoption of new technologies, new processes and new structures, and accelerate the development of standardization, serialization and generalization. For example, why does Sumitomo save fuel? Because it is equipped with a computer-assisted power control system connected to the hydraulic circuit, it uses a precise control mode selection system to reduce the consumption of fuel, engine power and hydraulic power. Another example is why Kobelco is better to drive? Because it uses an intelligent control system. Another example is why Liebherr works well? Because it has developed a control device for electronically controlling the work, it can adjust the working performance of the excavator according to the work requirements.
④ Update design theory to improve reliability and extend service life. The major exporters of excavators in the United States, Britain, and Japan are relatively successful in the theory of limited life design of excavators. The operating rate of excavators produced is 85% ~ 95%, and the service life is more than 10000h!
⑤ Strengthen the labor protection for drivers and improve their working conditions. For example, using a cab with a falling object protection structure and a tipping protection structure , installing adjustableelastic seats , and reducing noise interference with sound insulation measures .
⑥ Further improve the hydraulic system. This is more professional to say, friends who are interested can leave a message in the background for consultation.
⑦ Rapidly expand the application of electronic and automation technology on excavators. At present, more advanced excavators are equipped with an automatic engine idling and throttle control system, a power optimization system, a work mode control system, and a monitoring system.
