A concrete mixer truck, also known as a concrete mixing and transport vehicle, is primarily used for the long-distance transportation and on-site mixing of concrete in construction projects. It can maintain the uniform mixing of concrete and prevent segregation during transportation, making it a core specialized vehicle for infrastructure projects.

A dump truck is a heavy-duty freight vehicle engineered for efficient bulk cargo unloading, featuring a reinforced truck chassis and a hydraulically driven tilting cargo box—the core functional components. The cargo box is typically made of high-strength steel to withstand abrasion from gravel, sand, and ores, while the hydraulic lifting system enables quick rearward or sideward tilting for automatic unloading. It also comes with a sturdy frame, heavy-duty axles, and anti-skid tires for stability on rough terrain.

A cargo truck is a versatile freight vehicle built on a robust heavy-duty chassis, with a reinforced frame as its core structure. It is equipped with a flatbed, drop-side stakes or a detachable railing system for flexible loading and unloading. Key components include a high-power engine, durable suspension, load-bearing axles, and a braking system with anti-lock function to ensure transportation safety. Auxiliary parts like cargo tie-down hooks and side steps further enhance its practicality.

A tank truck is a specialized vehicle for transporting liquid or gaseous materials, consisting of a heavy-duty chassis, a sealed cylindrical tank, a loading/unloading system, and safety devices. The tank is made of corrosion-resistant steel or aluminum alloy to adapt to different media, equipped with anti-wave partitions to reduce liquid sloshing during transportation. Critical safety components include emergency shut-off valves, pressure relief valves, and static grounding devices to prevent leaks and explosions.

A fire engine (also called a fire truck) is a specialized emergency vehicle with a modular structure tailored for fire suppression and rescue. Its core components include a water/foam tank (storing fire-extinguishing agents), a high-pressure water pump (delivering water at high flow rates), hoses and nozzles of varying sizes, and a ladder system (for high-rise rescue). Additional equipment includes fire extinguishers, cutting tools, first-aid kits, and communication devices. The chassis is a heavy-duty truck frame with enhanced suspension for rough terrain.

A box truck, a typical enclosed cargo vehicle, features a rigid and enclosed rectangular cargo box mounted on a heavy-duty truck chassis—its core structure. The box is usually made of steel or aluminum for durability and weather resistance, with a rear roll-up door or side access doors for easy loading/unloading. Key components also include a reinforced frame, suspension system for load stability, and a cab with ergonomic controls for the driver. Some models add liftgates or cargo tie-downs to enhance functionality.

A sewage suction truck is a specialized vehicle for collecting and transporting liquid waste, composed of key components: a vacuum pump (the core power unit creating negative pressure for suction), a sealed sewage tank (storing waste with corrosion-resistant materials like steel), a suction hose with a suction gun, a discharge system, and a chassis (usually a heavy-duty truck frame for stability). Auxiliary parts include pressure gauges, safety valves, and cleaning systems to ensure operational safety.

A sprinkler truck is a specialized sanitation vehicle integrating water storage, conveyance and sprinkling functions. Its core structure includes a heavy/medium-duty chassis (brands like HOWO and Shacman available), a large-capacity steel water tank with anti-surge plates, a high-pressure water pump, and a multi-nozzle sprinkling system (front flush nozzles, side sprinklers, rear long-range cannons).

Tractor heads mainly consist of powertrain system (high-horsepower engine, efficient gearbox, heavy-duty rear axle), chassis framework (high-strength steel frame, suspension system, braking system), cab assembly (ergonomic driving space, intelligent control panel) and traction connection device (fifth wheel coupling). This structural design ensures robust power output, stable load-bearing capacity and reliable connection with semi-trailers.

Refrigerated trucks are mainly composed of chassis system (heavy-duty frame, high-power engine, stable suspension and braking system), insulated cargo compartment (honeycomb structure inner panel, polyurethane foam insulation layer, corrosion-resistant outer panel), refrigeration unit (compressor, condenser, evaporator, temperature control system) and auxiliary components (cargo fixing rings, temperature monitoring device, anti-condensation system). The fully enclosed and insulated structure design maintains a stable low-temperature environment inside the compartment and prevents external heat from entering, ensuring the freshness and safety of goods.

Powder and granular material transport vehicles, also known as bulk cement trucks, are specialized vehicles used for transporting powdery or granular materials such as cement, fly ash, lime powder, and grain feed.

Stake fence trucks are mainly composed of chassis system (frame, suspension, braking system, power unit), cargo compartment structure (removable metal stakes, anti-slip wooden/steel floor, adjustable side rails and top rails), loading and unloading auxiliary parts (side-mounted ladders, cargo binding rings) and cab assembly (ergonomic driving cabin with safety facilities). The open and flexible compartment design facilitates quick loading and unloading, and ensures good ventilation for goods.
