The “Golden Pair” for Rural Low-rise House Construction: Flat-mouth Mixer Truck and Model 25 Concrete Pump

At construction sites for rural self-built houses of no more than four stories, the traditional concrete work mode of “carrying loads by shoulder and transporting materials by hand” is being replaced by small machinery.

The multi-functional flat-mouth mixer truck and Model 25 concrete pump, with their flexible adaptability and high-efficiency operation capability, have become the new favorites of many rural households and construction teams.

How exactly do these two types of equipment perform? And what changes can they bring to rural house construction?

I. Core Parameters of the Two Machines: Price and Efficiency

1、Multi-functional Flat-mouth Mixer TruckPrice: The price of mainstream market models (2 m³ capacity) ranges from $10,000 to $12,000 per unit, while some basic models can be as low as $8,000.Working Efficiency: Integrating automatic feeding, mixing and transportation in one unit, it can achieve a daily output of over 200 tons with only 2 workers in operation. The mixing cycle is about 3–5 minutes per batch, and it can produce 10–15 m³ of concrete per hour, making it suitable for small-volume concrete work in rural areas.

2、Model 25 Concrete PumpPrice: The price of dual-power (diesel/electric) models is about $4,000 to $8,000 per unit, and lightweight models can be as low as $2,000.Working Efficiency: It can achieve a vertical conveying height of up to 60 meters (meeting the needs of 4-story buildings) and a horizontal conveying distance of 100–200 meters. The pumping capacity is about 10–30 m³ per hour, and it only takes 6–10 minutes to pour a single structural column—more than 10 times the efficiency of manual pouring.

For rural self-built houses of no more than four stories, the pain points such as narrow construction sites, high labor costs and inconvenient material transportation are exactly where these two machines can shine.
1、Flat-mouth Mixer Truck: Solving the Problem of “Small Sites + Flexible Operation”
Rural house sites are often limited in space, making it difficult for large mixer trucks to access. In contrast, the flat-mouth mixer truck, with its compact body (approximately 2 meters wide), can easily navigate village roads and courtyards. It eliminates the need for fixed mixing plants, as it can directly perform automatic feeding and mixing of sand, gravel and cement on the construction site, thus saving the cost of secondary material transportation. Meanwhile, it supports the mixing of dry-hard concrete, flowing concrete and mortar, meeting the material requirements of different components such as foundations, walls and floor slabs.
Take a 3-story, 120-square-meter self-built house as an example. The concrete volume that would take 5–6 workers 3 days to mix manually can be completed by just 2 workers in 1 day with the flat-mouth mixer truck, cutting labor costs by over 70%.
2、Model 25 Concrete Pump: Breaking the Labor Bottleneck of “High-rise Pouring”
In rural house construction, the vertical transportation of concrete for 4-story buildings used to be a major headache. Manual bucket passing is not only inefficient, but also likely to cause concrete segregation and insufficient compaction of floor slabs. The Model 25 Concrete Pump delivers concrete directly to the roof via pipelines, with its vertical reach more than sufficient to cover 4-story buildings (about 12 meters). Moreover, the pumping process ensures better material uniformity, which can enhance the structural strength of walls and floor slabs.
In addition, the machine features a small footprint (3.5 meters long and 1.45 meters wide), allowing it to be placed directly on the floor slab for operation. With remote control, a single worker can complete the pouring work, avoiding the safety risk of “high-altitude material dumping”.
3、Combined Use: Dual Optimization of Efficiency and Cost
The combination of the flat-mouth mixer truck and the Model 25 Concrete Pump enables seamless connection between “mixing and pumping”. After the mixer truck prepares concrete on-site, it directly discharges the concrete into the pump hopper, which then pumps it to the construction surface immediately. The entire process requires no intermediate transfer, which not only reduces material waste, but also shortens the construction period to one-third of that of the traditional mode.
Take a 4-story, 200-square-meter self-built house as an example. The comprehensive cost of using the two machines in combination (including equipment depreciation and labor) is about 12,000 US dollars, accounting for only 40% of the fully manual mode, while ensuring more stable project quality.

For rural households, the purchase cost of these two pieces of equipment may seem not low, but in actual use, they can not only shorten the house construction period (reducing from the traditional 2–3 months to within 1 month), but also enable users to recover costs quickly through external rental (with a daily rental fee of about $500–$800). As for construction teams, the high utilization rate of the equipment (which can serve multiple construction sites simultaneously) and low maintenance cost (with the service life of wearing parts increased by 30%) also make it a core tool for lightweight construction.
Shifting from a labor-intensive model to a mechanized and high-efficiency one, the combination of the flat-mouth mixer truck and the Model 25 concrete pump is making the construction of rural self-built houses more hassle-free, cost-effective and reliable. For rural households planning to build houses of no more than four stories, this may be a wiser choice than hiring manual labor.

Looking for real-world operation videos of these two machines?
I have sorted out the information about the real-world operation videos of these two machines in rural house construction as follows:

1、Multi-functional Flat-mouth Mixer Truck (Shandun Heavy Industry Model)You can search the keywords “Shandun Heavy Industry Flat-mouth Mixer Truck Operation Video” on short-video platforms (e.g., Douyin, Kuaishou) to see such scenarios:
The equipment automatically feeds sand, gravel and cement in rural courtyards, and directly discharges the mixture after completing the stirring process.
Cooperating with construction teams to pour foundations and walls, it can be operated by only 2 workers, eliminating the tedious work of manual shoveling.
2、Model 25 Concrete PumpSearch the keywords “Model 25 Concrete Pump Rural House Construction” to find real operation videos showing:
The pump delivers concrete vertically to the roofs of 3–4-story buildings through pipelines, replacing the manual work of “carrying buckets upstairs”.
Only 1 worker is needed to complete the pouring of structural columns and floor slabs via remote control, with the concrete remaining uniform and free from segregation during the pumping process.
The real operation videos of these two devices are relatively concentrated in the construction machinery category of accounts on short-video platforms. You can watch the real construction scenes by directly searching the above keywords.
