The inverted design of the bucket cylinder in the working device is quite ingenious. During conventional excavation operations, when the bucket cylinder is in a normal position, it is easily affected by problems such as the impact of materials and stress concentration caused by frequent telescoping. However, after the bucket cylinder is inverted, the stress mode can be cleverly changed, so that the impact force borne by the bucket cylinder during the operation can be distributed more evenly, effectively reducing the wear of key parts and greatly increasing the overall service life of the working device. Moreover, this structure can still maintain stable and reliable performance in long - term high - intensity excavation, loading and other operations, reducing the number of breakdowns and maintenance times caused by structural fatigue and other reasons, thus saving users a lot of time and maintenance costs.
The oil - bath air filter is like the "lung guard" of the equipment. It uses oil to absorb tiny particles such as dust and impurities in the air. Compared with traditional filters, its filtering effect is more excellent. It can prevent dust from entering the engine to the greatest extent, ensure the normal operation of the engine and extend the service life of the engine. The cover - type filter further protects the key components inside the equipment and prevents foreign objects from entering and affecting their normal operation. The radiator protection net can effectively block debris, branches and other objects in the working environment from approaching the radiator, avoiding poor heat dissipation of the radiator due to impact or blockage by foreign objects, ensuring that the equipment can work stably in high - temperature environments. The circuit - breaker pipeline return - oil filter finely filters the hydraulic oil, removes impurities in the hydraulic oil, maintains the cleanliness of the hydraulic system, reduces the wear of hydraulic components caused by impurities, and reduces the maintenance cost of the entire equipment, enabling each system to operate stably for a long time in a good environment.
The anti - steel - bar - winding device is specially designed for long and strip - shaped objects such as steel bars that often appear on construction sites. It can prevent steel bars from winding around the working device or traveling parts, avoiding equipment jamming, damage and other problems caused thereby, and ensuring the continuity of operations. The welded anti - collision beam is installed at key parts of the fuselage. In the event of an accidental collision of the equipment, it can absorb and disperse the energy generated by the collision, effectively protecting the main structure of the fuselage from serious damage and reducing maintenance costs. The cylinder piston rod protective sleeve provides an additional protective layer for the cylinder piston rod, preventing it from being eroded and scratched by sand, dust and other substances in a harsh environment, ensuring its normal telescopic movement and maintaining the normal working performance of the equipment. The heavy - duty platform walking frame bottom cover further reinforces the bottom of the walking frame, enabling it to resist various impacts and wear from the ground and enhancing the durability of the traveling device. The single - side 3 - crawler guard can not only protect the crawler from the impact and erosion of external objects but also facilitate the daily inspection and maintenance of the crawler, ensuring the traveling stability and safety of the equipment in all aspects, making the entire fuselage like being covered with solid armor and remaining safe and sound in various complex and harsh working environments.
The cab with an extra - large space provides operators with a very spacious range of activities, avoiding the sense of depression and fatigue caused by a narrow space during long - term operations. The humanized design is reflected in many aspects. The standard front - top guardrail can provide reliable protection for the driver in case of accidental rollover of the equipment, preventing objects from falling from above and causing harm to the driver. The front window adopts double - layer laminated glass. This kind of glass not only has good light transmittance but also has high strength and strong impact resistance. It is not easy to break even when subjected to external impact, and even if it breaks, it will not produce sharp fragments, fully ensuring the safety of the driver. Equipped with 5 LED working lights, it can provide sufficient and uniform illumination in working environments with relatively dark light, such as night construction or underground operations, enabling the driver to clearly observe the working area and its surrounding situation, ensuring the accuracy and safety of operations. The entire cab is as solid as a rock from the structure to the configuration, creating a comfortable and safe working environment in all aspects and greatly improving the working experience of operators.
Product Application Scenarios
The Liugong CLG922E excavator is a well - deserved and powerful assistant in the field of earth - work projects. Whether it is the large - scale earth excavation on construction sites or the foundation digging in community construction, the Liugong CLG922E excavator can quickly and accurately complete the earth excavation work by virtue of its powerful digging ability and high - efficiency operation performance. In the process of earth loading, it can quickly and orderly load the excavated earth onto transport vehicles with its flexible operation and appropriate bucket capacity, greatly improving the overall construction efficiency of earth - work projects. It is an indispensable key equipment in the construction of earth - work projects.
In road construction projects, the Liugong CLG922E excavator also plays an important role. In the early stage of road preparation, it can be used to dig drainage ditches on both sides of the road. By precisely controlling the digging depth and width, it can ensure that the ditches can meet the drainage requirements. When leveling the road surface, it can effectively repair the uneven ground with its bucket, laying a good foundation for the subsequent road paving. Moreover, when dealing with some obstacle removal, foundation earth excavation and other work in road construction, the Liugong CLG922E excavator can also complete the tasks excellently with its stable performance, helping to promote the smooth progress of road construction.
In water conservancy projects, the advantages of the Liugong CLG922E excavator are fully demonstrated. For example, when building irrigation canals, it can accurately dig out the shape of the canals according to the design requirements by virtue of its relatively large digging depth and good stability, and can also carefully repair the bottom and sides of the canals to ensure the quality of the canals and enable the smooth flow of water. In large water conservancy projects such as reservoir dam construction, it can also participate in the early earth excavation, foundation treatment and other work, contributing to the smooth development of the entire water conservancy project. Its reliable performance makes it a trusted equipment among water conservancy project construction teams.
For small - scale mining operations, the Liugong CLG922E excavator is fully capable of handling them. The mining environment is complex and harsh, with rugged ground and a large number of stones. However, the Liugong CLG922E excavator can move freely in such an environment by virtue of its powerful power, solid body protection and good passing ability. During the ore excavation process, it can use its strong digging force to break the ore and dig it out, and then load it onto transport vehicles. Even in the face of long - term high - intensity mining operations, the Liugong CLG922E excavator can also provide continuous guarantee for mining operations with its stable performance and reliable quality, improving the efficiency and benefits of mining operations.
