In construction projects, mining, infrastructure construction, urban renewal, and other fields, heavy industry vehicles (such as excavators, loaders, cranes, truck-mounted cranes, bulldozers, and pavers) are the workhorses of construction sites. While the basic performance of these vehicles (power, structural rigidity, and travel performance) determines their fundamental capabilities, it is the equipment they carry or have installed (attachments, auxiliary systems, and intelligent systems) that truly determines their unit-time productivity, operating costs, and operational flexibility.

In the commercial vehicle transportation sector, the terms "cargo vehicle" and "towing vehicle" are often used interchangeably in everyday language. However, from the perspective of construction vehicles or transportation engineering, their concepts, load characteristics, and driving risk control requirements are distinct:Cargo vehicle: refers to a freight vehicle with the inherent cargo-carrying capacity (whole vehicle type), not including those that are coupled or towed by other vehicles or trailers (such as ordinary trucks or construction trucks).Towing vehicle or towing combination: refers to tractor-trailers, semi-trailers, tractor-trailer trains, locomotive-drawn trains, etc., with a specific division of labor between cargo carrying and towing: the towing head is responsible for driving and steering, while the trailer bears the cargo load.

On construction sites, in mining, construction, agriculture, and forestry, construction vehicles are often used in these environments. Wheel dump trucks, tracked tippers, and tracked turners often undertake critical tasks such as loading, transporting, unloading, and turning materials. These vehicles operate in harsh environments, experience large fluctuations in loads, and have complex structures. Improper maintenance can easily lead to breakdowns and shorten their lifespan. Therefore, to extend the lifespan of these construction vehicles, regular maintenance is essential to minimize breakdowns. This article systematically summarizes and outlines key maintenance points for these two types of unloading/turning equipment from multiple perspectives for reference by equipment managers, maintenance technicians, and field operators.

Dump trucks (also known as "tipping trucks" or "dump trucks") are widely used in mining, earthwork, construction, road construction, and municipal waste disposal due to their ability to lift and unload cargo containers. However, their structural characteristics, heavy-load operation, and unloading dynamics also pose significant safety risks. Driving stability is closely related to loading and unloading operations. This article aims to systematically review the key safety points of dump trucks during driving and loading and unloading operations from a professional perspective, and provide management and operational recommendations.

In industrial and mining environments, loaders are essential construction machinery, widely used in mines, coal mines, construction sites, sand and gravel plants, and other locations. Industrial and mining environments place stringent demands on the adaptability, efficiency, and versatility of loading equipment. Depending on the workload, loaders vary in type and performance. Sugarcane loaders and telescopic loaders are two typical examples, each with its own unique advantages and applications. This article will provide a detailed analysis of the applications of these two types of loaders in industrial and mining environments.

Mechanized equipment is playing an increasingly important role in agricultural production, particularly in sugarcane planting, harvesting, and transportation. Sugarcane loaders (specialized or semi-specialized equipment) and general-purpose telescopic loaders (also known as telehandlers, telescopic boom loaders, or telehandlers) utilize modular attachment systems and variable arm lengths to efficiently handle agricultural materials such as sugarcane, straw, and fertilizer, demonstrating their potential for application in agricultural settings. For example, sugarcane loaders are equipped with a 360-degree rotating grab bucket, enabling side loading and front grabbing in the field, while their hydraulic travel system maintains stability even in muddy sugarcane fields. Telescopic boom models, with their 8-meter adjustable operating radius, can cross ditches or walls for tasks such as stacking feed.

The choice of loader for a construction site requires a comprehensive consideration of terrain conditions, workload intensity, mobility requirements, and cost-effectiveness. Due to their structural differences, wheel and crawler loaders exhibit significant performance differences. This article will comprehensively compare various aspects of the loaders, including their features, performance, and operating environment.

Mini loaders are highly efficient construction machines. Due to their compact structure and versatility, they are widely used in a variety of fields, including construction, agriculture, and gardening, as well as in confined spaces. Regular maintenance is crucial to ensure long-term, stable operation. This manual details the maintenance methods and precautions for each major component of a mini loader, helping users extend the life of the equipment and reduce malfunctions.

Backhoe loaders, with their combined loading and digging capabilities, are versatile equipment for small to medium-sized construction projects. In civil engineering, mountainous road construction, slope stabilization, water conservancy, highway embankment work, and mining operations, operators often encounter complex terrain characterized by uneven ground, variable geological conditions, unstable ground bearing capacity, and other challenges. Operating a backhoe loader in such environments significantly increases the risk and technical difficulty. Therefore, both operators and site managers should thoroughly understand the precautions and operational guidelines for backhoe loaders in complex terrain. This information is intended for equipment operators, personnel, and safety managers.

Loaders (also known as excavators) are widely used in earthmoving operations for roads, railways, construction, mining, and other projects. They are primarily used for loading loose materials such as soil, sand, gravel, and coal, and can also perform light excavation work. By changing attachments, they can also perform functions such as earthmoving, lifting, and loading/unloading logs. Due to the widespread use of loaders, it is essential to understand their various operating techniques and safety precautions before use.
