XCMG describes five integrated functions: loading, metering, mixing, transporting and unloading. The official specification lists a 4 m³ mixing quantity, a 700 L loading bucket and a drum rotation angle of 270 degrees. This arrangement allows the machine to support the movement of ingredients and mixed concrete within the site, reducing the need to organize each stage around separate equipment.

The stated applications include roads, railway works, retaining structures, dams and drainage projects, especially in remote locations. Its practical value comes from local production and placement flexibility. Mix design, material supply and quality-control arrangements should still be planned by the construction team so the SLM4 fits the concrete work package.
