Product Highlights
hydraulic excavator is a brand new product developed by brand itself by widely absorbing advanced technology of similar products abroad and adopting the latest technology. It is an efficient excavator with the latest technology, full attention to safety and environmental protection performance, and high production efficiency. Based on the full absorption of internationally advanced technology and independent innovation, the project has fully solved a number of core and key technologies of the 40-ton hydraulic excavator. The fully upgraded hydraulic excavator has more power, lower oil consumption and stronger operating performance. It can be widely used for irrigation and water conservancy, river dredging, municipal construction and small mine construction. It can meet different operations such as digging, breaking and dismantling, and its working condition adaptability is further strengthened.
Based on fully absorbing the advantages of the previous generation products, it adopts the latest separate pump independent control system and imported new main pump and main valve only for. With arm electronically controlled, for the same earthwork quantity, the efficiency will improve 7% and fuel consumption will reduce 10%. In addition, it reduces the impacts like the start and stop of arm and boom, and greatly improve maneuverability. By adopting large-bore bucket cylinder and arm cylinder, the digging force will be increased by more than 5%.
Adopt the engine that conforms to the national III emission standard, and customize the low-speed and high-torque full-electronic control engine that conforms to the working condition of excavator, the torque reserve will be increased by 15%. With the full-electronic control high pressure common rail engine technology, the fuel efficiency will be improved by 5%, and it is more energy-saving and environmental friendly.
Advanced excavator intelligent management system, using CAN bus communication and Internet of things technology, integrating the main control system, engine ECM, monitoring system, control panel, GPS cloud control system and on-site diagnosis system, to achieve digital sharing of machine information, improve the intelligence level of products. Convenient mobile phone APP micro service enables you to know the location, operation status, working time, fuel consumption and maintenance cycle of the excavator anytime and anywhere. The autonomous controller collects the altitude and engine inlet pressure of the vehicle position, automatically determines the database, and prompts the operator to select the plateau mode on the display. Intelligently match the hydraulic pump and engine power to guarantee the flow of pump output, reduce the engine speed loss ratio, prevent from black smoke and brakes, and thus ensure the efficiency of excavator.
Large new view cab, with lower noise, operating environment is more comfortable. The air conditioner has good refrigeration effect. Integrated control panel is more comfortable to operate. The 8-inch large display is more fashionable. One-button emergency stop switch makes it safer. With the family golden shield shape appearance, the line is steady, and thus the whole machine is more elegant. With simple painting and the high identification, the whole machine is full of the sense of power and three dimension, and is more impressive.
