Dongfeng 2 cbm concrete mixer trucks mix and supply concrete with higher mobility than fixed plants. Some use a tractor trailer unit for greater flexibility, and others have an extra axle for carrying larger loads that meet local regulations.
Tractor Unit with Trailer:
In this configuration, a tractor truck pulls a trailer with a concrete mixer mounted on it. This setup is beneficial for transporting the mixer over long distances or for supplying concrete to multiple locations from a centralized batching plant.
Extra Axles for More Weight:
Dongfeng concrete mixer trucks usually come with an appropriate number of axles to match the 2-cbm tank and local regulations. The most common six-wheeler has a front driving axle and a rear driving axle. Some versions may have an extra trailing axle to make them more stable when carrying heavier loads of up to 5 cbm.
Besides truck mixer's flexible transportation for concrete requirements, it's significant to know the other types available:
Static Concrete Mixers:
Static concrete mixers are fixed machines generally used at a central location to produce a high volume of concrete. They mix the ingredients of concrete in a stationary location for high precision and control over batch sizes. Static mixers are commonly used for large-scale projects where a constant supply of concrete is required. A plant may be used for concrete to be kept in a large tank and pumped out on demand.
Tilt Mixers:
Tilt mixers are commonly used in stationary mixer trucks. They have a drum that tilts to pour the mixed material. The drum rotates during the mixing process, and the tilting action allows for easy and controlled discharge of the mixed concrete into the desired location.
Reverse Drum Mixers:
Reverse drum mixers can be found in both stationary and truck mixer models. They have a drum that rotates in the reverse direction for mixing and discharge. Reverse rotation helps achieve homogeneous mixture and accurate discharge control. In addition, Dongfeng truck concrete mixers are commonly equipped with discharge chutes that can be maneuvered to different locations as required.
Planetary Mixers:
Planetary mixers are typically used in precast concrete plants or large batching facilities. Dongfeng planetary mixers combine the revolutionary motion of an internal mixing blade with central planetary gear to ensure thorough and rapid blending of materials. They are called planetary mixers because the mixing blades rotate around their own axis while orbiting around the periphery of a stationary drum. In central location only, Dongfeng planetary mixers are suitable for high-volume production and efficiency. They can also handle a wide variety of mix designs, including those with a high aggregate content.
The following are some adapted specifications and details about the maintenance requirements of the small concrete mixer truck.
Power source
The concrete mixer trucks have a strong engine that is able to mix fresh concrete while also doing other tasks. The engines are usually diesel engines, and their sizes range from 100 to 200 horsepower.
Tank volume
For a small truck, the concrete tank will be between 2 and 4 cubic meters. This means that the truck can carry about 2,000 to 4,000 liters of concrete. However, for a 2 cbm mixer, the capacity will be limited to 2 cubic meters.
Mixing system
Inside the tanks of the trucks are spiral-shaped blades. These blades can rotate both clockwise and counterclockwise. The task of the blades is to mix the concrete evenly, which helps to prevent the material from hardening.
Overall dimensions
A small mixer truck will have a length of about 5 to 7 meters with a width of about 2 to 2.5 meters. The height will be between 3 to 3.5 meters. The dimensions may vary based on the model and manufacturer.
Payload capacity
A small mixer truck with a 2 cbm capacity has a payload of about 2 tons (kg). The payload capacity refers to the maximum weight the truck is able to carry.
Wheel and tire
Usually, the small concrete trucks have 6 wheels and tires that are 12 to 22 inches in size. The mixer truck uses tires that function well on construction sites and urban roads.
Hydraulic system
The trucks are equipped with a hydraulic system that works to propel the drum mixer and maintain the stability of the truck during the process of mixing concrete as well as the transportation.
Fuel efficiency
A small concrete mixer truck's fuel use ranges from 8 to 15 liters per hour. This amount will change depending on factors like the mode, size, and load of the truck.
Regular inspections
Before operating the trucks, check the parts such as the engine, transmission, braking system, and tire condition of the mixer truck.
Lubrication
The moving parts of the truck, like chains, bearings, and the hydraulic system, should be lubricated on a regular basis. Doing this will keep it from wearing out quickly and will help to prevent any unforeseen breakdowns.
Cleaning
It is important to wash the concrete trucks after every use. This will help to maintain the truck's appearance and condition.
Maintenance of the tire
The tire pressure and conditions should be monitored and maintained regularly. This helps to ensure that the mixing truck maintains good stability and fuel efficiency.
Strict treatment and storage of the supplies
The supplies of the mixing truck, such as the hydraulic oil and lubricant, should be treated and stored according to the requirements of the manufacturers. This helps to ensure that the quality of the truck is maintained.
Due to their compact size, Dongfeng 2 cbm concrete mixer trucks are suitable for small-to-medium projects. They are convenient and capable of efficiently mixing and transporting concrete. Here are several application examples of how these trucks may be used in different industries and areas.
The following tips might be useful for buyers searching for a suitable Dongfeng 2 cbm concrete mixer truck.
Construction Project Size and Cement Demands:
Consider the size of the construction projects where the concrete mixer will be used. If the projects are relatively small, such as residential construction or minor infrastructure development, then a 2 cbm mixer truck will suffice. Also, think about how frequently the mixer truck is expected to supply concrete.
Mixer Truck Maintenance:
A concrete mixer truck will require maintenance and occasional repairs. Consequently, users will be more interested in the availability of servicing facilities and spare parts close by. If a mixer truck model is very popular, then it’s likely that many local service providers will be familiar with it. However, if the model is unfamiliar, it might be challenging to find skilled mechanics or spare parts.
Fuel Economy:
Since the mixer truck will likely cover many kilometers, choose a model with good fuel economy. A truck that consumes less fuel will lower operating costs and increase profit margins.
Mixer Truck Condition:
Factor the condition of the mixer truck into the buying decision. Older trucks with high mileage may come at a lower price, but they might present maintenance challenges and be less reliable. A truck in good condition with moderate mileage may be a more prudent investment despite the slightly higher initial cost.
Budget Constraints and Resale Value:
Finally, budget limits will play a central role in the buying decision. Ensure the choice of mixer truck corresponds with the investment needed to finance future projects. Also, think about the future resale value of the truck. Some models, especially those with greater capacities, tend to hold their value better and may be easier to sell at a later date.
Q1: How does a concrete mixer truck work?
A1: A mixer truck has a drum fitted on a truck chassis. In the drum, concrete is mixed and rotated during transportation to keep it fresh at the job site.
Q2: How is the concrete delivered from the mixer truck?
A2: Concrete from the mixer truck is delivered in the form of chute pouring or by reverse rotation from the drum as per the request of the customer or direction from the job site.
Q3: How long can concrete remain in a mixer truck?
A3: According to industry standards, concrete can stay in the mixer truck for 90 minutes to 2 hours maximum. After this time, the mixing should stop to avoid any issue with the setting of concrete.
Q4: What are some challenges facing the concrete mixer truck industry?
A4: Some concrete mixer truck challenges are the maintenance costs, supply chain disruptions, the fluctuating demand for concrete, etc.
