Performance Characteristics and Configuration Description of XC938 Wheel Loader
XC938 Wheel Loader is a new generation of high-end models built by XCMG, especially suitable for heavy load conditions. This product fully adopts foreign advanced design and manufacturing technology and is developed and designed through extensive market and technical research closer to the market. With superb performance, streamlined appearance characteristics, the reliability, safety, comfort and maintenance, and other aspects of the previous generation of products have been greatly improved. The main features are as follows:
Main performance and characteristics
The imported electric injection, turbocharged, air-to-air cooling CUMMINS B6.7 engine, which is electric start, electric flameout, and the emissions standard can meet the requirements of Eu Stage V emission regulations; air filter with three-stage filtration, which can adapt to dusty conditions; The engine not only has high reliability and adaptability, but also has the advantages of low fuel consumption and fewer emissions, adapts to a variety of working conditions, and is equipped with a variety of machines to meet the different demands of customers better.
The dual-variable system adopts an imported ZF-4WG160 gearbox, with four forwards and three reverse gears, electronically controlled automatic shifting, with KD gear, neutral start protection, and variable gear lock function; large capacity torque converter, high transmission efficiency, Effectively improve work efficiency and economic performance; the FNR switch integrated with the joystick of the work device can quickly and easily change the driving direction of the whole machine and reduce the shoveling and loading cycle time of the entire machine.
XCMG wet drive axle, maintenance-free multi-piece wet brake pads, prolong the service life of the axle; strong construction machinery drive shaft, strong impact resistance, high reliability of power transmission. 20.5R25 low-pressure wide-base radial tires are used, which have low rolling resistance and can effectively reduce tire wear. With the condition that the rear axle can swing, the tires have good off-road performance and passing performance and are fully adapted to driving and working on rugged roads.
The whole machine adopts a load-sensitive variable, a full-variable hydraulic system, provides pressure and flow according to the demands of the device, eliminates overflow loss, and significantly improves fuel and work efficiency.
The steering system adopts load-sensitive flow amplification technology, which is light and comfortable to operate, flexible steering, energy-saving, and consumption reduction—equipped with a hydraulically driven intelligent, independent cooling system. The fan speed is automatically controlled according to the oil and water temperature. Energy-saving and noise reduction have strong environmental adaptability; the fan can be turned over to effectively prevent the water tank from clogging and improve cleaning convenience. The triple hydraulic system is equipped with quick change and can be adapted to various tools.
Full hydraulic wet service brake and caliper disc parking brake, with low-pressure alarm protection, emergency brake, and parking brake in one, to ensure the safety of your operation, excellent brake components further enhance the reliability of the brake system.
Cab and control system
XCMG's new FPRS&ROPS micro-pressurized cab features ample space, wide vision, and good sealing. The use of a silicon oil shock absorber relates to the frame, which significantly reduces the vibration of the cab. Airbag damping compound control seat, comfortable operation; Intelligent temperature control, high power heating and cooling air conditioning, suitable operating temperature.
The structural parts and connecting rod mechanism pay attention to the overall structural strength through finite element analysis and load spectrum-based optimization design and fatigue test verification of the structural components of the heavy-duty loader; reduce stress concentration parts, eliminate local weaknesses, and fully ensure withstand rugged roads Face the strength requirements of structural components.
Increase the distance between the upper and lower hinge pins of the hinge center, disperse and reduce the stress of the hinge pins, and improve the service life of the bearing.
The lower hinge pin adopts double tapered roller bearings to increase the carrying capacity and improve the driving stability.
Using the welding toe fatigue life improvement technology to prevent the welding seam cracking of the whole vehicle under severe working conditions.
Powder electrostatic coating and unique anti-corrosion technology solve the problem of corrosion.
Working device and bucket
The working device is optimally designed and adopts a Z-type inverted six-bar linkage structure with a single rocker arm, a short tie rod, and a horizontal boom cylinder, superior working performance, and efficiency.
With the function of automatically leveling the bucket at any position, there is no need to adjust the bucket state during shoveling operation, which simplifies the process of the driver.
All hinge pin lubrication adopts a dust-proof structure, effectively preventing dust and protecting grease from pollution. It provides reliable protection for hinge pins and shaft sleeves. The standard configuration of a centralized lubrication system reduces maintenance time.
The bucket is made of high-strength wear-resistant plates, and the bucket teeth are made from internationally renowned brands, making it more robust and durable.
centralized lubrication system
The German SKF's original centralized lubrication system has excellent and reliable quality. Use a proper grease pump to lubricate each point regularly and quantitatively to ensure that each friction pair maintains a reliable and sufficient oil film to make it run normally. The lubrication system overcomes the shortcomings of the labor intensity of manual grease filling and the difficulty of controlling the lubricant filling amount and interval time.
GPS Reversing image and GPS technology
The advanced rear-view device provides the driver with a broad reverse working field of vision, which provides a reliable guarantee for safe operation. At the same time, GPS can realize remote data diagnosis function, monitor various technical parameters and operating conditions of the machine, and bring good data support for maintenance.
Electronic weighing system
The whole machine is equipped with an electronic weighing system. By collecting the pressure of the boom cylinder at a specific position, the system can directly give the particular weight of each transported material after automatic calculation and supports data printing and automatic statistics; it has a higher weighing precision, providing precise technical support for measuring.
