I. More energy saving and environmental protection
Uses internationally renowned brand engines. It meets the TIER3 emission standard, has the characteristics of strong power, low noise, low fuel consumption and low emissions, and can meet the needs of various construction conditions.
More efficient returns
1. The imported hydraulic components and positive flow control system prolong the service life of the whole vehicle and improve the operating efficiency. The new series of main valve has a series of regeneration, confluence, and priority functions to reduce energy consumption requirements. The engine and hydraulic system are completely used. Independent cooling system, automatic control fan speed according to water temperature and oil temperature, energy saving and noise reduction, meanwhile the fan has reverse function, which is convenient for cleaning the dust on the radiator.
2. Excellent and reliable electrical control system, to achieve the perfect match between power and hydraulic system, maximize the use of engine power, ensure fast and efficient operation of the machine, and reduce energy consumption: the system is equipped with H (heavy load), S (standard) , L (light load) three working modes. When the machine is powered on, the control system defaults to L mode. The throttle knob can adjust the corresponding working mode and speed of the engine, and at the same time control the main pump power valve, so as to control the power of the main pump in different modes. H (heavy load), S (standard), L (light load) power control is to control the engine speed and main pump power according to different operating needs.
Third, more reliable and durable
1. The XE750D uses the Donaldson FRG series of heavy gray air filters imported from the United States. At the same time, the exhaust gas injection system is added, and the filtration efficiency reaches 99.99%, which can adapt to multiple dust and wet conditions.
2. The XE750D is equipped with a four-stage fuel filtration system (two-stage coarse filtration + two-stage fine filtration), which effectively filters impurities in the oil and ensures the engine's long-term, high-load, continuous and reliable operation under severe operating conditions.
3. Establish a solid finite element model of the whole machine, and perform static and dynamic simulation analysis on the whole machine. All key parts of the boom and stick are forged design, with good bearing capacity and high reliability. Analyze or calculate fatigue life of key structural parts such as working devices to ensure long-term and durable work. The carefully designed and reinforced front-end working device has undergone fatigue strength tests, and its reliability meets the needs of heavy-duty mining and mining. It adopts mine-specific rock bucket teeth, which has strong penetrating power and good wear resistance.
4. The I-beam structure of the main body of the turntable is welded by reinforced steel plates, which improves the ability of the main body to withstand positive and negative bending moments and ensures the strength requirements of the upper machine. Left and right skirts designed with D-shaped structural steel can effectively prevent impact deformation.
5. The vehicle's electrical system adopts aviation-grade protection. The connector uses high-grade galvanic connectors with good electrical continuity and excellent protection. The vehicle wiring harness adopts new detachable all-plastic fixtures, which are fixed and reliable. And prevent abrasion; the vehicle's work light uses high-brightness, low-energy-consumption LED work lights, which can work well even in foggy weather, and the life of the LED lights can reach 60,000 hours.
6. The chassis adopts full-protection rail clamps, and the drive wheel side adopts a chain rail retaining structure, which effectively prevents stones from entering the crawler chain rail and reduces wear; the double-reinforced crawler pads have strong grip and better steering performance.
More intelligent control
"Smart" builds the future, and the intelligent control system is newly upgraded: (1) Adopting the new self-developed intelligent control system (XEICS), which efficiently matches the power of the hydraulic system and the power system, intelligently adjusts the working state, and saves energy and efficiency; (2) Equipped with an on-site diagnostic expert system to provide digital diagnosis support for maintenance technicians, improve on-site processing solutions, fast and accurate; (3) complete IoT platform architecture, remote monitoring and diagnosis through intelligent cloud control system and XCMG handheld client, The real-time working condition data is clear at a glance, and customers can control the vehicle dynamics in time; (4) Advanced self-matching of multiple modes of power, adapting to different tools and working conditions, adaptively adjusting the state of the excavator.
Five, more comfortable and safe
1. The XE750D uses an enhanced cab with FOPS certification. The front window of the cab adopts a fence-type metal protective net to effectively protect the operator's safety. The cab frame with thick profiled steel is sufficient to protect the operator's safety. High-performance silicone oil shock absorbers imported from Japan can eliminate the interference of machine vibration to the operator.
2. The new streamlined cab space design and car-grade luxury interior create a comfortable working environment for the operator; the interior of the cab has a large operating space, ample footstep space and a large amount of storage space behind the suspended seat. Designed with gentle walking pedals and comfortable foot pedals. The control device conforms to the principle of ergonomics, and various operation buttons adopt an intelligent layout, which is within reach. Large operating field of view, panoramic front and side windows, and rear window provide the best field of vision in all directions; high-power cooling and heating air-conditioning ensures rapid heating and cooling in the room, making the cabin more comfortable.
Six, convenient maintenance
1. XE750D daily maintenance is all within reach. Whether it is fuel filter, oil filter, pilot filter or water tank, electrical components can be directly maintained on the platform, easy to operate and save costs; optional fuel , Hydraulic oil, gear oil centralized filling system, convenient for rapid detection, filling or replacement of oil.
2. XE750D has built-in expert diagnosis system, which includes engine controller, main controller, electronic monitor, GPS and fault diagnosis instrument, and data and information communication between devices through CAN bus; the application of expert diagnosis technology can realize the whole machine Real-time monitoring, remote monitoring, fault diagnosis, parameter and function adjustment, provide fast and timely fault judgment analysis and processing solutions for product market after-sales service. In addition, remote fault diagnosis can be achieved through the GPS system.
