The invention relates to an operating table base (16) for an operating table (10), comprising at least two extractable transport rollers (32a, 34a). The operating table (10) rests on at least one support element of the operating table (10) in the retracted state of the transport rollers (32a, 34a). The operating table (10) is movable on the transport rollers (32a, 34a) in the extracted state of the transport rollers (32a, 34a). The operating table base (16) further has a first mechanical adjusting unit (40) by means of which the state of the first transport roller (32a) is changeable at least from the retracted state into the extracted state, as well as a second mechanical adjusting unit (42) by means of which the state of the second transport roller (34a) is changeable at least from the retracted state into the extracted state. The first adjusting unit (40) and the second adjusting unit (42) are drivable by a first drive unit (80) which is connected to the first and the second adjusting unit (40, 42) via a mechanical connecting means (24).
