Types of Liebherr Concrete Mixers

Liebherr concrete mixer trucks are available in two main types: the mixing and transport concrete mixer truck. The first type consists of mixers with fixed drums that rotate in one direction for mixing concrete and in another direction for unloading. Transport mixer trucks have drums mounted on a truck chassis or trailer that rotate to transport the mixed concrete.

Another way to look at types of Liebherr concrete mixers is based on their power sources. Therefore, concrete mixer trucks can either be fuel-powered or electric-powered. Fuel-powered concrete mixer trucks use diesel fuel or any other form of fuel energy. On the flip side, electric-powered trucks use electricity from power grids or rechargeable batteries.

Concrete mixer trucks can also be categorized depending on their availability of the four wheels that allow the truck to move around easily. An all-in-one concrete mixer machine has the capacity to mix, transport, discharge, and pump the concrete from a single unit. Concrete mixer pumps have an in-built concrete pump, and they are typically mounted on a truck chassis. On the other hand, a separate portable concrete mixer machine is used to mix the concrete. This unit is then transported to the site using a different mode.

According to the capacity of the presiding storage unit, concrete mixer trucks can also be classified as large, medium, or small capacity.

Using the function of different components of the concrete mixer truck, one could also classify the truck into a feeding, mixing, discharging, and transport area.

Specification and Maintenance of Liebherr Concrete Mixers

Specifications

• Capacity:

  Liebherr concrete mixer capacities can hold volumes of concrete ranging from 5 cubic feet (140 liters) to 1,000+ cubic feet (28,000+ liters), depending on the model and type. They can be found in small portable mixers or large truck mixers.

• Power Source:

  The power sources for the mixers are varied and include diesel engines, electric motors, hydraulic motors, or combinations of these. Truck-mixed concrete mixers usually rely on the truck engine or a separate diesel engine to power the mixing.

• Mixing Methods:

  The methods employed by Liebherr mixers are varied. They can be drum mixing, reversing drum mixing, and axial-flow mixer or consolidating mixer mixing, to name just a few of the different methods.

• Dimensions:

  The dimension sizes have typical height, length, and width measurements, which are approximately as follows. For truck mixers, the height is about 12.5 ft (3.8 m), the length is 25 ft (7.6 m), and the width is 8 ft (2.4 m). For large mixers, the height is about 13.5 ft (4.1 m), the length is 40 ft (12.2 m), and the width is 8.5 ft (2.6 m). For the small mobile mixer, the specifications are height: 6 ft (1.8 m), length: 10 ft (3 m), width: 5 ft (1.5 m).

Maintenance

• Clean:

  Using clean water, the outside of the mixer is first cleaned to remove dirt that may have been present from the construction site. Care should be taken to ensure that the cleaning method does not damage any components of the mixer.

• Remove/Adjust:

  Once the mixer is cleaned, the water should be removed from the drum to reduce the risk of corrosion. Water can be retained in the mixer for maintenance of the drum and its operations. However, the amount of water should be kept to a minimum so that the total weight does not affect the mixing performance.

• Lubrication:

  Regular lubrication of the moving parts of the Liebherr concrete mixer, like bearings, seals, and hinges, is crucial. Components will operate smoothly and experience fewer wear and tear damages if lubrication is applied to them and enhances their lifespan.

• Water Consumption:

  It is important to understand the water consumption of the concret mixer during operation so that the daily mixing water can be taken into account and planned out carefully to maximize efficiency. Knowing the consumption of every part can help with overall production.

• Regular Maintenance:

  Developing a schedule for routine maintenance of the mixer helps to find problems at an earlier stage, lowering the cost of repairs and the likelihood of unexpected failures that can cause downtime. The mixing drum, motor, gearbox, hydraulic components, and bearing should be part of the maintenance program.

Usage scenarios of Liebherr concrete mixers

Both stationary and mobile concrete mixers serve a variety of purposes in the larger construction industry. The choice of machine often depends on other infrastructure needs, such as how far away the supply needs to be, whether built roads can support the weight of the machine, and what volume of concrete needs to be mixed and/or delivered on a daily basis.

The larger the machine, the farther it can travel in a day and the greater capacity for mixing concrete it has. Mobile concrete mixers with Liebherr concrete mixer truck parts can supply large-scale construction projects from a distance. They are typically used for large masonry projects, including the construction of:

• Industrial or commercial buildings
• Infrastructure projects such as bridges, dams, and highways
• Mega construction projects such as airports, power plants, and large-scale housing developments
• Large-scale foundation projects
• Large-scale civil engineering projects

In areas where progress needs to be made quickly and on a daily basis, mobile concrete mixers are ideal construction machines for use in:

• Mass construction projects, such as large-scale housing developments and infrastructure projects where a constant supply of concrete is required.
• Remote construction sites where access is limited, and concrete needs to be mixed on-site to reduce transportation costs and minimize delays.

Large-scale public works projects and massive construction projects typically require a strong, consistent, and sustained supply of cement. It may be more economical and efficient to deploy a stationary cement plant on-site to mix cement at the source where it is needed or closer to where raw materials will be sourced. On-premise cement mixing plants are ideal for:

• Large-scale construction projects located a long way from established infrastructure
• Site at high elevations where access is limited, and mixing concrete locally is necessary to minimize transportation costs and reduce delays
• Remote locations where raw material sources are far away from both roads and cement processing facilities

Zoned-based mixing is ideal for energy construction projects including:

• Power generation facilities such as solar fields and wind farms
• Mining projects that require the construction of facilities deep inside a mine
• Oil and gas facilities including refineries and offshore platforms
• Water and wastewater facilities including desalination plants and water treatment facilities

How to Choose Liebrerr Concrete Mixers

When selecting concrete mixer machines, buyers should consider several factors. Firstly, they should clearly define their project types and applications. For instance, if mixing concrete would be used for large capacity projects like massive infrastructure construction, long-distance transportation, and commercial batch production, a stationary concrete mixer will be appropriate. On the other hand, if the mixer will be used in confined spaces or low, small-capacity projects, a portable concrete mixer will be appropriate.

Also, buyers should determine the concrete mixer machine's capacity they need. They should assess project demands, mixing frequency, and volume requirements to determine the optimal capacity. This will help them avoid over-sized or under-capacity mixers. Additionally, buyers should consider the mixing method of the machine. Some projects require the buyers to have the mixer with a hydraulic system, tilting drum for uniform mixing, or central drum for cost efficiency.

More importantly, buyers should consider the power source of the machine. They should determine if they need an electric-concrete mixer-machine or diesel. This will depend on the project's location and accessibility. Additionally, buyers should consider the concrete mixer machine's design that fits their usage. For more massive, frequent concrete mixing, the batch type will be appropriate. On the other hand, the continuous type will be suitable for projects that require uninterrupted mixing.

Finally, buyers should determine the market price range of the machine before making their order. This will enable them to make a cost comparison and determine an economical mixer for their project.

Q&A

Q: What is the difference between a concrete mixer and a concrete mixer truck?

A: A concrete mixer mixes the raw ingredients of concrete. It can mix cement, water, aggregate, and sand. The concrete mixer is usually found at the manufacturing facilities of concrete. On the other hand, a concrete mixer truck's primary purpose is to transport mixed concrete from the manufacturing facility to construction sites.

Q: What are the differences between mixing methods in concrete mixers?

A: The two primary methods of mixing concrete are radial and axial mixing. Radial mixing involves the movement of materials in a radial direction. It includes the use of mixed drums with radial fins. On the other hand, axial mixing involves moving material along an axis. It includes using concrete pumps and horizontal screw conveyors.

Q: What is the role of a concrete mixer in the construction industry?

A: Concrete mixers are the backbone of the construction industry. They prepare the concrete that is the primary component in most construction projects. Not only do they ensure the uniform manufacturing of concrete, but they also make sure that it is efficiently and conveniently provided where it is needed.
