Small loaders are suitable for large amounts of concrete on construction sites. When mixing concrete, the raw materials (stones, sand and cement) required by general construction companies are mostly transported from the material yard to the mixer by hand carts. This method of manual feeding and manual transportation is labor-intensive. Large-scale production efficiency is low, and it is no longer suitable for modern production requirements: and large-scale loaders are not suitable for use. For this reason, agricultural tractors are converted into practical small-scale loaders to effectively solve this problem.
