The whole machine is made of high-quality wear-resistant materials, and the key parts have been specially strengthened, which greatly enhances the anti-wear ability. For example, the main body of the machine is made of high-strength alloy steel, which has excellent hardness and toughness. Compared with ordinary steel, it can better resist external impacts and various wear and tear generated during the operation process. When the bucket frequently makes digging movements and contacts with hard objects such as the ground and stones, the bucket made of high-strength alloy steel can effectively avoid cracks, deformation and other situations, and maintain a good working state for a long time. The key components have also undergone special heat treatment processes and surface hardening treatments. For example, the transmission gears of the loader, after heat treatment such as quenching, have a denser internal structure, greatly improved hardness and enhanced wear resistance. They can still stably transmit power under long-term high-speed operation and high-load working conditions, reducing the incidence of failures caused by wear. Meanwhile, the surface hardening treatment forms a solid protective layer on some parts that are prone to corrosion and wear, such as the connection joints of the working device, which greatly extends the service life of these components. In addition, the overall structural design follows the mechanical principles, with a scientific layout. The connections between various components are stable and can reasonably share the load. During long-term high-intensity operations, there will be no structural damage caused by excessive local stress. For example, the frame adopts a box-shaped structure, which has strong bending and torsion resistance. Whether it is during full-load digging or long-distance material transportation, it can ensure the overall stability of the loader, ensuring that the equipment can operate stably and reliably for many years, saving users the cost of maintenance and replacement.
It is equipped with multiple safety protection systems to ensure the safety of operations. Firstly, it is equipped with an advanced braking system, adopting the dual-circuit hydraulic braking technology. With this braking method, when any one of the circuits fails, the other circuit can still ensure an effective braking effect, greatly improving the braking reliability. Under the working condition of full-load high-speed driving, once an emergency occurs, the operator only needs to gently step on the brake pedal, and the loader can brake smoothly in a short time, avoiding safety accidents such as collisions. Moreover, the braking system also has an anti-lock function. Even when braking on a slippery road surface, it can keep the wheels rolling to a certain extent, preventing the vehicle from losing control and skidding, ensuring the safety of personnel and equipment at the operation site. Multiple safety protective devices are also set around the equipment. For example, high-strength guardrails are installed around the cab. The guardrails are made of thickened steel pipes and can effectively resist accidental impacts from the outside, avoiding the harm caused by flying stones, debris and other objects to the operators. Meanwhile, an overload protection device is set on the working device of the loader. When the weight of the excavated or loaded materials exceeds the rated load, the device will be automatically triggered to suspend the action of the working device, preventing damage to the mechanical structure caused by overload and avoiding potential safety hazards, ensuring the normal operation of the equipment and the personal safety of the operators. In addition, the design of the cab fully considers the vision needs of the operators. It adopts large-area glass windows. The front windshield has good light transmittance and impact resistance, and the layout of the windows is carefully designed, almost eliminating the blind spots. Sitting in the cab, the operator can clearly see the situation around the excavation point when performing the digging operation, or observe the surrounding traffic conditions and operation environment during the driving process, so as to discover potential dangers in advance and make correct operation responses, effectively reducing safety accidents caused by limited vision.
It creates a comfortable and pleasant working environment for the operators. The cab has a spacious space and a reasonable layout. Operators can freely stretch their limbs in the cab without feeling cramped. Compared with similar equipment, there is obviously more headroom and legroom. Even during long-term operations, there will be no sense of depression due to the narrow space. Moreover, the internal layout of the cab is reasonable. Various operation buttons, instrument panels and other items are all in positions that are convenient for operators to reach and observe, making the operation more convenient and further enhancing the comfort experience of the operators. The seats are carefully designed according to the principles of ergonomics. The height, angle of the seats and the curve of the backrest are all in line with the physiological curve of the human spine, which can provide good support for the waist and back of the operators, effectively dispersing the body weight and reducing the fatigue caused by long-term sitting operations. The surface of the seats is made of high-quality breathable materials. Even when working in hot weather, it can remain dry and comfortable, allowing operators to focus on work in a comfortable sitting position and improve work efficiency. To create a comfortable working environment, the cab is also equipped with an advanced air-conditioning system. This air-conditioning system has multiple functions such as cooling, heating and dehumidifying, and can quickly adjust the temperature and humidity in the cab according to different seasons and external environmental temperatures, keeping them within a suitable range all the time. In addition, an air purification device is installed to effectively filter out dust, exhaust gas and other pollutants entering the cab from the outside, providing fresh and healthy air for the operators, allowing them to work easily in a comfortable and pleasant environment and reducing fatigue and discomfort.
The operation is extremely simple, and even beginners can quickly get started. The operation panel is designed to be simple and clear. Various function keys and joysticks are reasonably arranged according to the functional areas, and each key has a clear label, so that the operator can understand the corresponding function at a glance. For example, the start button, light control button, work mode switch button and other buttons are all concentrated in an easy-to-operate area. Operators do not need a complicated learning process and can quickly get started with operating the equipment, greatly saving the time cost of familiarizing with the equipment operation and improving work efficiency. The operation of the working device is realized through intelligent joysticks. The operation force of the joysticks is moderate and the hand feeling is comfortable. Operators only need to gently push or pull the joysticks to accurately control the actions of the bucket such as digging, lifting, turning and unloading. Moreover, the response speed between the joysticks and the working device is extremely fast, almost achieving real-time synchronization. Operators can flexibly perform various complex operations according to the actual operation needs, whether it is a fine digging operation or a rapid loading and transfer work, which can be easily handled, making the operation more simple and convenient. In addition, the loader is also equipped with some intelligent auxiliary functions, which further improve the convenience of operation. For example, it has an automatic leveling function. When performing site leveling operations, the operator only needs to set the reference height for leveling, and the loader can automatically adjust the height and angle of the bucket according to the information fed back by the sensors, achieving high-precision site leveling without the operator repeatedly manually adjusting, greatly reducing the labor intensity of the operator and improving the quality and efficiency of the operation at the same time.
