Small loaders are suitable for small and medium-sized construction, and a large amount of concrete is required at the construction site. When mixing concrete, most of the raw materials (stones, sand and cement) needed by the general construction enterprises are transported from the stockyard to the mixer by hand carts for mixing. This method relies on manual loading and manual handling, which has high labor intensity and low production efficiency, and is no longer suitable for modern production requirements: large loaders are not suitable for use, so agricultural tractors are converted into practical small loaders, Effectively solve this problem.
