What is the vehicle that pours concrete called?

Concrete mixer truck or simply mixer truck. Below is extended information about concrete trucks: Function of concrete trucks: They are specialized trucks used to transport ready-mixed concrete for construction; Due to their shape, they are often called "snail trucks". Operating principle of concrete trucks: The truck is equipped with a cylindrical mixing drum to carry mixed concrete, and the drum keeps rotating during transportation to prevent the concrete from solidifying. After delivering the concrete, the inside of the drum is usually rinsed with water to prevent hardened concrete from occupying space. Composition of concrete trucks: A concrete mixer truck consists of a truck chassis and specialized concrete mixing and transportation equipment. In China, the chassis of domestically produced concrete mixer trucks mostly use Class II universal chassis provided by vehicle manufacturers. The specialized mechanisms mainly include power take-off, front and rear drum supports, reduction gear, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. The working principle is that the power from the truck chassis is extracted through the power take-off device to drive the variable pump of the hydraulic system, converting mechanical energy into hydraulic energy and transmitting it to the fixed displacement motor. The motor then drives the reduction gear, which powers the mixing device to stir the concrete.
During my years working at construction sites, I often dealt with this type of vehicle—the concrete mixer truck! It's specifically designed to transport and mix wet concrete to prevent it from solidifying. The truck features a large rotating drum that keeps the concrete fresh by continuously mixing it while on the move. Upon arrival at the construction site, the concrete can be discharged from the rear or used in conjunction with a pump truck for pouring. Workers commonly refer to it as the 'mixer truck,' which is quite fitting. This vehicle significantly enhances construction efficiency, as manual methods were too slow and prone to errors. In terms of design, modern trucks have optimized the chassis and control systems, making them durable and safe. Always remember to check the tires and ensure proper lubrication of the mixing drum to avoid breakdowns. After all, in construction projects, it's a critical component that can't afford delays.
Honestly, the mechanism of concrete mixer trucks is quite fascinating. They use the engine to drive a hydraulic system that rotates the mixing drum, which contains spiral blades to blend materials and prevent water separation and solidification. Continuous mixing during transport ensures uniformity. For discharging, the drum is tilted or a discharge port is opened to release the material. There's also a variant called the concrete pump truck, equipped with a high-pressure pump and telescopic boom, which directly pumps concrete to designated points like high-rise buildings with precise flow control. Maintenance focuses on oil circuits and seals, with regular hydraulic oil changes required. Operators need training to ensure smooth driving and avoid sharp turns that could cause concrete segregation. These details make construction more efficient and safer.
In my impression, the vehicle used for pouring concrete is the concrete mixer truck. They evolved from old trucks and have now become essential in construction. The cylindrical structure allows for automatic mixing of materials, greatly saving manpower. Commonly seen on construction sites for transportation and unloading, they are paired with pump trucks to improve pouring accuracy. Their functions are simple yet practical, and maintenance is easy to grasp. Fellow workers all know not to let the drum idle for too long to avoid wearing out the shaft. Technological advancements have made construction faster and more environmentally friendly.
