7 Ton 4.2cbm Front End Loader Xc978 Bucket Wheel Loader with CE
XC978 wheel loader is a new generation XC9 series loader, which absorbs foreign advanced design and manufacturing technology and is developed by market segmentation. The whole machine meets the requirements of high-intensity, continuous and heavy-duty operation, and has greatly improved reliability, comfort, maintainability and work efficiency, and has obtained good customer feedback. The design concept of the whole machine highlights economy and emphasizes practicality.
Engine
Equipped with Weichai WP10.5H engine, turbocharged, electric start, electric flameout, strong power, large power reserve; three
-stage air filter, specially designed for the harsh working environment of the construction machinery industry, using DOC+DPF+
SCR technical route, emissions meet China's IV stage standards; multi-stage fuel filter, fuel water removal filter, good fuel
adaptability, to ensure the cleanliness of the engine system, proprietary engine curve, according to working conditions,
with a variety of working modes, higher economy.
Double variable system
Adopt self-developed high-end electronic control MYF260A gearbox, the whole box adopts efficient three-element torque converter, helical gear transmission, full flow electro-hydraulic control system for power shift, with front four and rear four gears, neutral protection, KD gear forced downshift, power cut and other electronic control functions, strong bearing capacity, high transmission efficiency, convenient maintenance, long gear life and other characteristics, advanced performance, can simplify the driver's operation, can effectively reduce the driver's work intensity, adapt to the loader various operating conditions of the use requirements, and improve work efficiency. Large carrying capacity, fully meet the power requirements required by the loader.
Drive axle
The wet drive axle, super load capacity. Maintenance-free wet drive axle, multi-friction braking, stable braking, safe and reliable, can withstand ultra-heavy load conditions. The rear axle center swings, reducing the impact of additional torque and external load on the transmission system. The key block type construction machinery transmission shaft has strong impact resistance and high power transmission reliability. 26.5 - 25 tyres are adopted, and the rear axle can swing around the center, so it has good off-road performance and passing performance, and is suitable for driving and working on rough roads.
Hydraulic system
The hydraulic system is equipped with the third generation constant variable hydraulic system with self-developed load-sensitive pressure compensation technology, which improves the working ability and working efficiency of the whole machine under compound working conditions, saves engine power, and saves more than 5% energy compared with the second generation constant variable technology. The pilot handle integrates FNR shift function, which is convenient to operate. New type high position hydraulic oil tank and filter system, improve hydraulic fluid cleanliness and circulation efficiency. The steering limit adopts hydraulic flexibility and mechanical rigidity, first flexible and then rigid to reduce impact.
Brake system
Full hydraulic wet brake system with low pressure protection function, independent brake circuits of front axle and rear axle,
emergency brake and parking brake in one Hand brake adopts hydraulic caliper disc brake to ensure operation safety, and when the engine is not working, it can still release the brake of the whole machine.
Cab and control system
Beautiful and elegant shape, standard reversing image, wide vision, low vibration, low noise, comfortable driving; exquisite interior, configuration storage compartment, teacup holder, cigarette lighter, coat hook and other humanized facilities, excellent ergonomic design, comfortable environment, easy operation.
High performance shock absorbing seat with multi-directional adjustable steering column can meet the requirements of different drivers.
Frame
The front frame adopts four-plate box structure with good rigidity and strong impact energy absorption. CAE analysis optimization, strengthen
important bearing parts; overall large section structure, can withstand various working conditions of torsion and impact load, fully ensure the structural
strength of the frame. The rear frame is designed with super heavy load structure, and the whole structure is analyzed by rigorous finite element
simulation to strengthen the weak points and ensure the structural strength of the frame.
The height of the rear frame tail is reduced, so that the radiator is fully exposed, and the "one-stop" maintenance convenience is improved.
Maintenance convenience features
Electric rear flip type large side door hood, engine air filter, diesel filter element, oil filter element, oil filling and inspection and radiator
maintenance, etc., easy and simple; transmission filter and filler outlet design, various oil level inspection, oil addition and grease filling
and other maintenance points are arranged in easy access. Centralized electrical fuse box, maintenance more convenient, high
reliability. Remote centralized drainage, centralized pressure measurement, convenient daily lubrication and maintenance.
Working gear and bucket
The working device adopts Z-type reverse six-link structure. After optimization design, the lifting force of boom cylinder is 8% higher than that of
existing products, and the unloading angle and digging depth at any position are improved, which can better meet the requirements of different working conditions. With bucket high-level dumping automatic leveling and electromagnetic lift limit technology, shorten the working cycle time. Dustproof seal structure is adopted for all hinge point pin lubrication to protect grease from pollution and prolong the service life of pin.
