Excavators, as highly efficient engineering machinery, are widely used in construction, mining, road construction, and other fields due to their powerful working capabilities. To ensure the stable operation of excavators in various complex environments, the lubrication and maintenance of attachments are particularly important. This article will focus on commonly used excavator attachments—such as hydraulic breakers and buckets—and discuss how to properly lubricate and maintain these attachments to extend their service life and improve work efficiency.

Large excavators operate in industrial and mining environments, such as mines, open-pit quarries, and infrastructure earthmoving, often running continuously for hours or even tens of hours. Under prolonged operation, fatigue accumulates in various systems, wear accelerates, and potential hazards arise. To ensure equipment reliability, safety, and economic lifespan, a systematic routine inspection immediately after operation is crucial. This article analyzes key inspection items for large excavators after long-term operation from a professional perspective and provides practical operational suggestions for on-site maintenance management and work teams.

Tracked excavators, with their large ground contact area and traction, have a significant advantage in operating on complex terrain. However, even these tracked "steel behemoths" face serious challenges when dealing with mud, water, snow, or slippery, soft soil. In engineering environments such as mining, infrastructure, and industrial projects, tracked excavators (crawler excavators, track-type excavators) offer a clear advantage over wheeled equipment on soft, slippery ground.

With their unparalleled road maneuverability, rapid relocation capabilities, and relatively low ground damage, wheeled excavators have become a mobile workhorse in numerous fields, including earthmoving, municipal construction, agricultural and forestry reconstruction, and disaster relief. In mines, construction sites, roads, and municipal construction, wheeled excavators have become a common operating equipment due to their maneuverability and adaptability.

Excavators are indispensable heavy machinery used in construction, mining, and infrastructure development. Due to the inherent risks associated with their operation, proper safety procedures are crucial for preventing accidents. This article will detail how to effectively prevent high-risk behaviors during excavator operation, ensuring safe operation.

Excavators are highly integrated electromechanical hydraulic heavy machinery, and due to their operation in harsh and complex construction environments, their lifespan, performance, and reliability heavily depend on the quality of daily maintenance. For operators and managers, understanding the key points of maintaining the major components of an excavator is fundamental to extending equipment lifespan, reducing malfunctions, and improving efficiency. This article will introduce the daily maintenance methods and precautions for six major components: the engine, hydraulic system, undercarriage (chassis), working mechanism (boom, dipper arm, bucket, pins, etc.), electrical system, and attachments/connecting parts (pins, couplings, quick-change mechanisms, etc.), focusing on their functionality and operability.

In modern construction projects, excavators are often equipped with various attachments to handle different tasks such as earthmoving, crushing, trench digging, and material handling. Proper use and maintenance of these attachments not only prolongs their lifespan and reduces downtime, but also improves construction efficiency and ensures safety. This article focuses on typical attachments, including hydraulic breakers, buckets, and hydraulic booms, discussing three aspects: "Precautions for Use + Maintenance Tips + Common Faults and Prevention".

In construction projects, excavators, as highly efficient heavy machinery, are widely used in earthmoving, mining, road construction, and other fields. Depending on their mobility system, excavators can be categorized into wheel excavators and track excavators. These two types of excavators have significant differences in their suitable environments, performance, and advantages. Understanding these differences is crucial for operators, managers, and purchasing personnel.

As a crucial piece of construction equipment widely used in construction, mining, agriculture, and other fields, excavators are core equipment for modern engineering projects. Their selection directly impacts construction efficiency and cost control. Depending on the scale of the project, working conditions, and specific task requirements, various models are available on the market. From large to small excavators, each type has its own advantages and application scope. This article will analyze the characteristics of different types of excavators in detail, based on machine size classification (large >35 tons, medium 15-35 tons, small 4-15 tons, mini <3 tons), and provide scientific and reasonable selection recommendations for specific working conditions.

Mini excavators are construction machines designed for work in tight spaces. They are compact and easy to maneuver, making them widely used in urban construction, interior renovations, and pipeline installation. Because of their versatility and ease of operation, mini excavators are very popular. However, to truly master their operation, whether you are an operator or a supervisor, you should carefully review the mini excavator operation manual to better understand its operation and management.
