What is the advantage of small self-feeding mixer truck over traditional mixers?
The traditional mixer used in the past will have a non-uniform situation when mixing concrete. When the concrete is used, it must be stirred a few times manually. This will lead to unqualified concrete, resulting in poor quality of the project. .

Then the small self-propelled mixer truck can solve these problems well, whether it is C50 model concrete for road construction, C20 and C25 concrete for building, or C40 concrete for repairing water channel.

The small self-feeding mixer with full-time four-wheel drive and professional mixing blades can evenly stir the concrete without any auxiliary tools. It is very convenient and practical.
