About Mixer Truck
A mixer truck, also known as a concrete mixer truck or cement mixer truck, is a specialized vehicle designed for transporting concrete or cement for construction purposes. These trucks are equipped with a cylindrical mixing drum for carrying the mixed concrete.If you need concrete pump truck, please click.
Internally, the drum resembles a cylinder with tapered ends and is fitted with clockwise arranged blades. During transportation, the mixing drum rotates continuously to prevent the concrete from solidifying. After delivering the concrete, the interior of the mixing drum is typically rinsed with water to prevent residual concrete from hardening and occupying space, thereby preserving the volume of the mixing drum.

Things to note when buying a Concrete Mixer Truck
Precautions for buying a concrete mixer truck
1. Choose the right load capacity. This mainly refers to the choice of tank volume. For example, a mixer truck with a large load capacity has a relatively high transportation efficiency, but the corresponding cost is also high.
If the construction site you work on is relatively small and the road is narrow, it is best to choose a smaller mixer truck; if the construction site you work on is relatively large, it is best to choose a larger mixer truck, so that the load capacity is large and the profit is relatively high.
2. Choice of mixer truck material. The most feared thing for a mixer truck is a failure during transportation. If a failure is not handled in time during transportation, it will cause the concrete to solidify. In serious cases, the tank may be scrapped.
Therefore, attention should be paid to the choice of materials. The reducer, hydraulic motor, radiator and other components of the mixer truck must undergo quality tests.
3. Reasonable structural design. Reasonable structural design can ensure convenient operation and more thorough unloading. If the unloading is not thorough, concrete residues will easily accumulate in the mixing tank, which will reduce the effective volume of the tank over time and make it more difficult to clean up.
Finally, choosing a good supplier can solve all your problems. JNHTC has more than 20 years of experience in mixer truck manufacturing and has received praise from customers in many countries.

How many hours can concrete be stored in a mixer truck?
The storage time of concrete in a mixer truck is influenced by various factors, including the properties of the cement, the type of mixer, and the characteristics of the concrete. Generally, concrete should not remain in the mixer truck for more than 2 hours. Beyond this time, the concrete may start to segregate, resulting in performance issues.
Additionally, the time from when the concrete is mixed until it is delivered to the site is critical. If the time between mixing and delivery (including any waiting time) is controlled to within 90 minutes, the concrete’s workability should not significantly degrade, allowing for normal use within 2 hours.
However, if there are delays during transportation, such as a breakdown or extended waiting periods, the concrete’s properties may be negatively affected. Therefore, to ensure the quality of the concrete, it is recommended to use it within 2 hours. If this time is exceeded, the concrete’s performance may diminish, potentially requiring re-mixing.
In summary, to maintain the quality of the concrete, both storage time and factors such as temperature and humidity during transportation need to be carefully managed. If long-term storage is necessary, using appropriate additives and curing methods may help preserve the concrete’s performance.

Mixer Truck Motor and Reducer
High Quality, Low Failure Rate
Detailed explanation
The gearbox of a concrete mixer truck is a critical component that plays a vital role during the loading, transporting, and unloading processes. Its main function is to keep the concrete agitated, preventing segregation, which ensures the quality of the concrete and increases the transport distance. The gearbox must continuously provide power to deliver the necessary torque and rotational speed for mixing, while also withstanding the axial and radial loads from the fully loaded drum, as well as shock loads, especially during high-speed braking, turning, or descending hills.
Structure and Working Principle
The structural design and working principle of the gearbox are crucial to the performance of the mixer truck. Currently, planetary gear transmission systems are widely used in the final drive of the mixing drum. Planetary gear transmissions are known for their compact size, light weight, high load-bearing capacity, and high transmission efficiency. They offer a large transmission ratio and can be configured in multiple stages for greater transmission ratios. This system combines fixed-axis transmission with planetary transmission, which is far superior to fixed-axis transmission alone. It is particularly suitable for applications that require large transmission ratios, high load-bearing capacity, and limited installation space. Moreover, planetary gear transmissions operate smoothly and are highly resistant to impact and vibrations, making them ideal for the low-speed, high-torque operation of special construction machinery like mixer trucks.
Evolution of the Gearbox
The development of mixer truck gearboxes has progressed from chain and sprocket drives to bearing coupler drives, eventually evolving to hydraulic systems combined with gearboxes. This evolution better meets the demands of different working conditions. The gearbox, being a crucial support point for the mixing drum, must bear two-thirds of the drum’s weight, in addition to the added loads during transportation. This necessitates a gearbox with significant load-bearing capacity. As the quality requirements for transported concrete increase, so do the performance demands on the gearbox.
Gearbox Eccentricity Structure
The eccentricity structure of the gearbox is a key component that determines its operational performance. There are two main forms: external and internal drum gear structures. Each has its advantages and disadvantages. The external structure is easier to integrate into the spatial layout but has higher manufacturing costs. The internal structure is more cost-effective but is constrained by spatial limitations. Therefore, when selecting the gearbox’s eccentricity structure, factors such as the gearbox’s quality and manufacturing costs must be considered.
In summary, the gearbox of a mixer truck, through its unique design and efficient working principle, provides critical support for concrete mixing and transportation, ensuring the quality of the concrete and the efficiency of the transport process.
