The machine features a vehicle, along with extending arms and a series of different controls. Depending on the type of aerial lift you choose, the arm may be flexible and articulating, or it may be telescoping instead. This will extend the arm straight out. It may move up and down as well, but it will not have the articulation of other arms. The basket or platform will typically have controls as well, so the workers in the platform will be able to move the arm as needed. In addition, there are often connections for power tools in the lift. Some may also have specialized equipment attached.
