Concrete mixer trucks 8m3

Types of concrete mixer trucks 8m3

A concrete mixer truck 8m3 is an essential piece of equipment commonly used at construction sites. Like most concrete mixers, it has a rotating drum which mixes concrete. However, it also features a large storage container that can store and transport large amounts of concrete. There are two main categories of concrete mixer trucks: the continuous rotation type mixer and the reversible drum mixer truck.

• Continuous drum rotation concrete mixer trucks: Continuous concrete mixer trucks have the ability to produce large amounts of concrete—and keep the drum rotating continuously. However, they may not have the capacity to hold and transport concrete. Once the raw materials are mixed and entered into the truck, the mixing will continue for as long as the drum is rotating. The continuous rotation drum concrete mixer generally fits the demands of larger construction projects. They are often used to build high-rise buildings, large bridges, and dams where a constant supply of concrete is required. A major benefit of this type of concrete mixer is that it can produce concrete of uniform quality and consistency. They are able to do this without any interruption. Projects that require large amounts of concrete continually would ideally use this type of mixer.
• Reversible drum rotation concrete mixer trucks: A reversible drum mixer truck works by reversing the drum's direction to mix the raw materials. Concrete is mixed when the drum rotates in one direction. It is discharged when it rotates in the opposite direction. Reversible cement mixer trucks are suited for smaller, more medium-sized construction projects. They can also be used for rural and urban infrastructure development. Examples include mixing concrete for schools, hospitals, and residential buildings. They also fit the bill when constructing roads, drainage systems, and other civic amenities. A reversible drum mixer generally has a more compact design and smaller capacity than continuous rotation mixers. This makes it well-suited for localized construction activities where space is limited, and mobility is required.

Specification and Maintenance of Concrete Mixer Trucks 8m3

The specifications of concrete mixer trucks can differ considerably, based on the model and manufacturer.

• Truck Size: Generally, the mixer truck is between 7 and 12 meters in length. The truck size correlates directly with its capacity, which can range from 5m3 to 16m3.
• Weight: The weight of a concrete mixer truck is also an important parameter. The overall weight of 8m3 concrete truck mixers is around 14000 kg.
• Power: The truck features a strong diesel engine with a power of 240 to 300 horsepower. It is capable of carrying out more than 15,000 kg of payloads with more than 10-15% power to spare.
• Transmission: A concrete truck mixer generally has a manual or automatic 10-16 speed transmission. Some newer vehicles might feature the more modern AMT.
• Wheel: The number of wheels bases the truck on the vehicle's capacity and weight. A concrete mixer truck typically features 6 or 8 wheels. A concrete truck with more weight capacity, such as 12m3, will most likely have 8 wheels.
• Cylinder: The truck has a mixing cylinder attached at an angle on the backside of the truck. In general, the mixing capacity of this cylinder is between 6m3 and 16m3. The mixing battlements inside the cylinder rotate around its axis to mix concrete uniformly. The mixing speed is usually between 2 and 18 rpm.
• Discharge: The discharge method refers to how the concrete is released from the mixer truck. It can either be discharged at an open site (usually in construction and infrastructural projects) or into a concrete pump (usually in residential construction).

Maintenance Methods

Regular maintenance of concrete mixer trucks will improve their performance and extend their lifespan. Therefore, it is essential to check the mixer truck frequently and carry out regular maintenance.

• Daily Inspection: Carry out a thorough inspection of the truck before use. Check the water level, fuel level, oil level, and pressure of the hydraulic system as well as the air pressure in the tires. This will help identify any possible issues before use.
• Cleansing: Regularly clean the truck to remove any buildup of concrete, dirt, or debris that has accumulated over time. Take care to clean the water tank and discharge chutes properly.
• Lubrication: Lubricate all parts of the truck that require it, such as pivot points, bearings, and sealing mechanisms.
• Tire Maintenance: Ensure that the tires are filled with air to the recommended pressure. Rotate the tires frequently to avoid uneven wear. Clean the tires to prevent the buildup of concrete.
• Regular Servicing: Have the truck inspected at regularly scheduled intervals by qualified personnel. This could include changing oil and filters, inspecting for leakages, and calibrating systems.
• Safe Driving Practices: Practice safe driving when operating the mixer truck. Avoid sudden braking and acceleration. Maintain a steady speed. The overall aim is to prevent the mixing of concrete from being uneven and to avoid putting unnecessary stress on the truck.

Some scenarios of concrete mixer trucks 8m3

Given their large capacity, flexibility, and convenience, concrete mixer trucks 8m3 are primarily used in large construction projects like business and infrastructure development, urban construction, and road building.

• Big construction

  Concrete mixer trucks are a common sight in any big construction project. High-rise buildings and infrastructure projects require a sturdy and voluminous supply of fresh concrete. This makes large concrete mixers the truck of choice by construction teams.

• Business and infrastructure development

  Concrete mixer trucks are also widely used for the construction of roads, bridges, airports, and other infrastructural facilities. The demand for concrete in business and infrastructure development is high, and so using concrete mix trucks is very convenient and effective.

• Urban construction

  Concrete mixer trucks help resolve many issues commonly faced during urban construction, like:Reduced travel time to construction siteMinimised queuing timeFewer interruptions to trafficConvenient delivery of concrete.

  Due to their large capacity, trucks are especially useful for delivering ready-mixed concrete to construction sites with space constraints. The front and rear wheels of the mixing truck can be steered, which makes it easy to manoeuvre even in tight spaces. Concrete mixer trucks also deliver concrete in a timely manner, so there is rarely any delay in work.

• Road building

  Building roads requires large volumes of concrete at regular intervals to keep surfaces uniformly constant. This prevents centre cracking and ensures the road remains level. Using large-capacity concrete mixer trucks for building roads helps achieve all project goals without delays and efficiently.

How to choose concrete mixer trucks 8m3

When it comes to selecting an 8-cubic-meter concrete mixer truck, buyers need to pay close attention to various factors like truck type, engine power, mixing method, discharge method, axle, water supplying system, sealing system, fuel consumption, automatic control system, anti-overflow system, operational safety, maintenance, and inspection, and certification.

• Truck type: Consider the truck type based on the application. For on-site mixing, a transit mixer would be the most suitable. For hauling concrete from the plant to the site, consider using a standard concrete transport truck.
• Engine power: The engine power, usually measured in horsepower (HP), is what drives the concrete mixer truck. A powerful engine is essential for transporting heavy loads over long distances and diverse terrains. Consider the total gross vehicle weight (GVW), which is the weight of the truck plus the maximum load it can carry, including the axle configuration, which impacts the engine power needed. A truck with a higher GVW and more axles requires more power.
• Mixing method: Buyers will have to choose between a backward mixing truck (which offers a high homogeneous degree of concrete) and a forward mixing truck (which is suitable for various materials to be mixed and is more efficient for mixing other materials, such as seeds and fertilizers).
• Discharge method: Select the appropriate discharge method according to the construction site's requirements. Use the open-top discharge concrete mixer truck for construction sites with a mixing plant and open-top discharge. Use the rear axle or rear discharge for an easy-to-access construction site.
• Axle: The number of axles in the concrete mixer truck directly affects its payload capacity and stability. For heavy-duty transportation that requires high payload capacity, choose a truck with more axles (e.g., 4x2, 6x4, or 8x4). For occasional heavy-duty transportation, consider a truck with a higher fuel economy and maintenance costs (e.g., 4x2 or 6x2).
• Water supplying system: Depending on the type of concrete to be mixed (e.g., high-performance, ordinary, etc.), buyers will need to select a water-supplying system that meets the mixing demands. For example, a buyer may need to choose a water-tank system equipped with a water tank and a water pump.
• Sealing system: The sealing system's reliability is crucial in preventing concrete spillage or leakage during transportation. A good-quality sealing system can provide a tight seal, reducing the risk of any incidents.
• Fuel consumption: Concrete mixer trucks can be categorized by fuel type (diesel or electric). Large-volume transportation requires diesel, while short-distance transportation prefers electric due to its lower fuel consumption and cost.
• Automatic control system: Choose the degree of automatic control system according to the fleet management requirement. For example, if there is a demand for anti-overflow and automatic cloud control, selecting a truck with an anti-overflow system and cloud control is necessary.
• Anti-overflow system: If the drivers are prone to overflow situations or frequent transportation to sites with a high overflow risk, it's worth considering trucks with anti-overflow systems. These systems can help prevent overflow and reduce the risk of accidents.
• Operational safety: Things like ensuring proper training for operators, regular inspections, and implementing safe handling practices are crucial regardless of the specific make and model of the concrete mixer truck.
• Maintenance and inspection: Make sure the concrete mixer truck is easily maintained and inspected, thus helping reduce the cost of maintenance.
• Certification: Ensure the concrete mixer truck has responsible certifications and adhere to the relevant international standards.
