Six Competitiveness of 1.8m3 self loading concrete mixer – Core Advantages
The advantage of production efficiency
In the traditional construction mode, it takes 5-10 minutes for the loader to load, 10-15 minutes for the mixing station to mix, and the round-trip transportation of the tank truck takes longer. The self loading cement mixer truck single operation cycle only takes about 12 minutes, which is 2-3 times that of the traditional model.
The advantage of venue adaptability
The weight of the mobile self loading cement mixer is only 6300kg, the body is lighter, and the requirements for road conditions are low; the hinged steering design, with a turning radius of only 2355mm, can easily pass through narrow passages, country roads and other complex road conditions.
Manpower cost advantage
The traditional model requires 3-4 people (loader driver, mixing station operator, transport truck driver, unloader). A small self loading concrete mixer truck can replace the loader + mixing station + transport tanker, reducing the procurement cost of 2-3 equipment.
Quality advantages of concrete
The electronic metering system accurately controls the ratio of raw materials and reduces the waste of raw materials; there is no problem of separation and initial condensation of concrete transportation, and the concrete qualification rate is higher, reducing the cost of rework.
Advantages of durability and maintenance

Applications of Small Self-Loading Concrete Mixers
Rural self-built houses and small civil buildings
Rural self-built houses, rural residential transformation, small factory construction and other projects generally have problems such as narrow sites and poor road conditions. EP1.8Q self mix concrete truck has a small body and can drive directly into the narrow construction site and mix concrete on the spot, which can flexibly adapt to the construction rhythm of small civil buildings.
Rural roads and municipal small-scale projects
Rural highway hardening, municipal sidewalk laying, small bridge maintenance and other projects are usually decentralized and small-scale operations, and it is difficult for large mixers to enter the site. The concrete mixer truck can directly mix concrete on the roadside site and use it as it mixes, which adapts to the pouring needs of linear engineering such as roads and bridges.
Narrow sites and urban small-scale transformation projects
In urban old community transformation, basement construction, interior decoration concrete pouring, small commercial building construction and other scenarios, there are common problems of narrow construction space and large equipment cannot enter the site. The width of the 1.8Q body is only 2340mm, which can easily pass through the narrow passage.
Remote areas and outdoor emergency construction
Water conservancy projects in mountainous areas, road maintenance in remote areas, small-scale foundation projects in the field, emergency repair projects, etc., far away from large mixing stations and construction supporting facilities. EP 1.8m3 self loading concrete mixer truck has its own feeding, mixing and transportation functions, and can complete concrete supply independently without relying on external equipment.

FAQS
Q1: What is the actual concrete production efficiency of EP1.8Q self loading mixer?
A: The rated production capacity of the mini self loading concrete mixer is 5 times/hour. The actual production efficiency is affected by the concrete ratio, raw material supply, construction site and other factors. It can complete 4-5 stirrings per hour, and the daily output can reach 60-70m³.
Q2: Can the equipment be used in sub-zero environments? What should I pay attention to?
A: The self load mixer can be used in a sub-zero environment, but anti-freeze measures need to be taken: replace antifreeze engine oil and antifreeze liquid, and add low-guling point diesel; after operation, put the water in the water tank, pump and water pipe to prevent freezing and cracking of the parts.
Q3: How to calibrate the electronic metering system of the equipment? Is the error rate high?
A: The electronic metering system has been calibrated before leaving the factory, and it can be calibrated regularly during use to ensure the accuracy of the ratio. Under normal use, the measurement error rate is ≤2%, which can meet the ratio requirements of concrete construction.
Q4: How to clean up the concrete residue in the mixing tank? Will it affect the next use?
A: After the operation, it is necessary to clean the mixing tank, bucket and chute immediately with a high-pressure water gun to remove the residual concrete; if it is not cleaned for a long time, the concrete clumping will lead to a decrease in mixing efficiency, so it is important to clean up in time after each operation.
Q8: Is it difficult to operate the equipment? How long will it take for a novice to learn?
A: The self loading cement mixer truck adopts hydraulic pilot operation, which is light and effort-saving control, and the operation interface is clear and intuitive. No professional mixer driver qualification is required. After 1-2 days of basic training, the operator can master the basic operation process.
