A hydraulic tipper typically consists of several key components: the hydraulic cylinder, which provides the lifting force; the tipping body, which is the container that carries the load; the hydraulic pump, which generates pressure to operate the cylinder; and the control system, which allows the operator to manage the tipping action. Additionally, the chassis supports the entire structure and may include a frame and wheels for mobility. Together, these parts enable the efficient unloading of materials by tipping the container at an angle.
