Abstract
A chassis of a transportable device including a base structure, four casters arranged thereon, four lowerable and raiseable support feet also mounted on the base structure, and a hydraulic support foot actuating device. The hydraulic support foot actuating device has a reservoir (), a pump () manually operable by hand or foot, four support foot linear actuators () and a purely hydro-mechanical pipe and valve arrangement () which connects the reservoir (), the pump () and the linear actuators () to one another. Therein, by means of hydraulic fluid delivered by the pump () from the reservoir () the two support feet assigned to two primary linear actuators () can be fully extended until a mechanical stop is reached while raising the base structure by first applying pressure to the two primary linear actuators () before applying pressure to the two other, secondary linear actuators ().
