XE75U hydraulic excavator can be used for digging, loading, levelling, 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 urbanization, many infrastructure projects, such as municipal maintenance, landscaping, environmental protection, water and electricity facilities and property management, have created a vast market space. Design use: suitable for suburban and narrow areas; ambient temperature: -15℃～40℃; Working objects: soil below grade III and lose materials.
Central technical performance and characteristics:
Newly designed appearance
By cooperating with a well-known domestic construction machinery design company, the new generation's appearance has a family-style, fashion atmosphere, and a rich sense of technology. The new panoramic cab has a larger internal space. Using a large-area high-strength tempered glass cover guarantees the strength of the cab, and at the same time, the cab has a broader view.
New power system
Adopt Japanese Kubota V2607 engine to meet North America Ter 4F emissions Characteristics Four-cylinder and direct injection — lower maintenance costs and fuel requirements than EFI engine, and lower filter element maintenance costs. Turbocharging — high torque at low speed and low power loss at a plateau. Maintenance convenience — all the maintenance parts of this engine are arranged outside, which is convenient for daily maintenance.
New intelligent control system
The new colour large screen LCD monitor, conforming to ergonomics requirements, has complete instrument information. More automatic control functions can intelligently diagnose the fault causes and effectively shorten the troubleshooting time. The electronic control system possesses automatic idle speed and acceleration, engine start protection, engine overheating protection and other practical functions. The automatic idle process ensures that the machine will reduce the engine speed when the joystick is at the 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 back 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 solid digging force and excellent operating efficiency. By adopting newew generation of toad-sensing hydraulic systems, the system pressure loss is much less. The output power of the constant power variable piston pump will constantly 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; the compound action being more flexible, and the levelling 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 a U-type plate by way of compression modelling 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 the platform adopts an I-beam structure, and the side beam adopts a D-shaped cross-section structure, which makes the whole unit more reliable. By adopting the X frame chassis structure, stiffener plates are inside under the frame, which can form a box body with a large cross-section and achieve better bearing performance. The weight of the upper carriage will be evenly appltod on the track beam to reduce the track beam's local stress concentration. Adopt the international standard reinforced track, it is more reliable, and maintenance will be faster and easier.
Air prefilter system
The new air prefilter can effectively filter large particles of impurities from entering the air filter, thus pprolongingthe air filter's service life.
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. The 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 the air filter, which can prolong the air filter's service life. The whole machine is standard equipped with a grease gun bracket and tool case, which makes the entire machine's lubrication maintenance and storage of commonly used repair tools convenient.
