XE75U Crawler Excavator Highlights
XE75U hydraulic excavator can be used for digging, loading, leveling, ditching, crushing, drilling, clip cutting, lifting and other functions, which has played an increasingly important role in hydropower, transportation, municipal, garden, farmland reconstruction, oil pipeline, and other small-scale construction and production field. Especially with the rapid development of urbanization, a large number of infrastructure projects, such as municipal maintenance, landscaping, environmental protection, water, and electricity facilities and property management, has created a huge market space. Design use: suitable for suburban and narrow space; ambient temperature: -15℃～40℃; Working objects: soil below grade III and loose material.
Main technical performance and characteristics:
Newly designed appearance
Through cooperating with domestic well-known construction machinery design company, the new generation appearance has family-style, fashion atmosphere, and a rich sense of technology.
The new panoramic cab has a larger internal space. By use of large-area high-strength tempered glass cover, the strength of the cab is guaranteed, and at the same time, the cab has a wider view.
- New power system
Japanese Kubota V2607 engine to meet North America Tire4F emissions
Four-cylinder and direct injection — lower maintenance costs and lower fuel requirements compared with EFI engine, and lower filter element maintenance costs.
Turbocharged — high torque at low speed and low power loss at plateau area.
Maintenance convenience — all the maintenance parts of this engine are arranged outside, which is convenient for daily maintenance.
A new intelligent control system
The new color large screen LCD monitor, conforming to ergonomics requirements, has complete instruments information. More automatic control function can intelligently diagnose the fault causes and effectively shorten the troubleshooting time. Electronic control system possesses the automatic idle speed and acceleration, engine start protection, engine overheating protection and other practical functions. The automatic idle function ensures that the engine will automatically reduce the engine speed when the joystick is at a neutral position, reduce unnecessary fuel consumption, and reduce noise and exhaust emissions. When the joystick is operated again, the engine speed will resume. At the same time, it has a rearview camera to access the rear view of the excavator from the instrument.
- New load-sensitive hydraulic system
With the latest technological achievements, it features low energy consumption, rapid response, accurate control, and small impact, and maintains a strong digging force and excellent operating efficiency. By adopting a brand new generation of load sensing hydraulic system, the system pressure loss is much less. The output power of constant power variable piston pump will always adapt to the opening of the multi-way valve element and there is no excess flow loss, which can achieve the flow allocation unrelated to load, the compound action is more flexible, and the leveling action is smoother.
- With three major structural parts upgraded and optimized, it is more reliable and durable
Partially strengthen the parts with great stress on the boom, the arm adopts U-type plate by way of compression modeling and welds together with the upper plate, which makes its life longer. With a standard configured new bucket, unloading material will be faster and easier. The main beam of platform adopts I-beam structure and side beam adopts D-shaped cross-section structure, which makes the whole unit more reliable. By adopting an X frame chassis structure, there are stiffener plates inside the underframe, which can form a box body with a large cross-section and achieve better bearing performance. Weight of upper carriage will be applied on the track beam evenly to reduce the local stress concentration of track beam. Adopt the international standard reinforced track, it is more reliable, and maintenance will be faster and easier.
- Air prefilter system
The new air pre-filter, which can effectively filter large particles of impurities from entering air filter, and thus prolong the service life of air filter.
- High precision fuel filter
large Euro Ⅲ high precision fuel strainer equipped with oil-water separator, filter area is 1.5 times with the same size of other models.
- Convenient maintenance and service
Fully open rear hood and side door, daily maintenance points are within reach. Rear engine hood and side door are all made up of sheer metal parts, which are environmentally friendly. Add prefilter to adapt to rough working conditions with more dust and effectively filter and prevent large particles impurities from entering air filter, which can prolong the service life of air filter. The whole machine is standard equipped with a grease gun bracket, tool case, which makes the whole machine’s lubrication maintenance and storage of commonly used repair tools convenient.
