Loaders (such as wheel or skid-steer loaders) scoop, lift and move materials with efficiency. Graders are graders with long knives which are used to smooth surfaces, as well as to make ground level. The compactors use the weight or vibration to compact the soil or asphalt or gravel- which makes the surfaces stable and durable. Collectively the tools will allow accurate terrain shaping, preparation of foundations and quality paving and is a precursor to safe, long-lasting construction vehicles.
