Bulldozers, rollers, and motor graders are essential heavy-duty construction equipment in modern road construction. Their proper operation directly impacts project quality and safety. They play a vital role in the pavement construction process, involving earthmoving, compaction, and leveling. Proper use of these equipment not only improves construction efficiency but also ensures project quality. This article discusses the special precautions required when using bulldozers, rollers, and motor graders in pavement construction to ensure operational safety and effectiveness.

Spider cranes (also known as spider cranes), with their uniquely compact design, exceptional stability, and flexible outrigger system, have become essential equipment for lifting and hoisting in confined and crowded spaces, such as indoor renovations, historic districts, equipment-intensive factories, and courtyard operations. In industrial and mining environments, such as factory renovations, refrigeration equipment installation, and wind turbine foundation construction, limited space, narrow passageways, numerous equipment obstructions, and complex ground conditions are common challenges. Traditional large-scale lifting equipment often makes access and deployment difficult, potentially leading to construction delays and high costs.

Concrete mixer trucks (hereafter referred to as mixer trucks) and concrete pump trucks (hereafter referred to as pump trucks) are core equipment in modern construction. Their coordinated operation spans the entire concrete pouring process, from transportation to placement. For large and medium-sized projects, concrete pouring efficiency, quality, and safety are crucial. The mixer truck is responsible for transporting and mixing concrete en route to ensure uniformity; the concrete pump directly transports concrete vertically and horizontally through pipelines, completing the pouring process. This collaborative model significantly improves construction efficiency and reduces manual intervention. It is particularly suitable for projects with high concrete demand, such as high-rise buildings and large foundations. Improper coordination can lead to pipe blockage, segregation, or equipment damage, so strict adherence to operating procedures is essential.

Forklifts are essential equipment in logistics, warehousing, and loading and unloading operations. As core equipment in modern logistics and production, their stable operation is directly related to operational efficiency and personnel safety. Their working environment often involves high loads, high frequency, and complex operations, so the risk of failure is not low.

Terrain forklifts, designed for harsh terrain, are widely used in outdoor work environments such as mines, construction sites, and warehouses. Their enhanced off-road capabilities, higher ground clearance, rugged tires, and powerful powertrains make them indispensable material handling tools for these rugged environments.

With the advancement of logistics automation, manual and remote-controlled forklifts have become complementary in warehousing scenarios. Forklifts are essential equipment for industrial warehousing and logistics handling. As common types of forklifts, manual and remote-controlled forklifts each have their own characteristics and applicable scenarios. Manual forklifts rely on manual operation for flexibility, while remote-controlled forklifts utilize intelligent control for precise operation. Below, we will compare and analyze the operating precautions for these two types of forklifts from an operational perspective to help operators better understand the safety requirements and operating techniques for forklifts.

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.
