A work table is described, having a frame (2) which is adjustable especially with respect to its height and for the adjustment of which at least one electric motor (4) with a control device (7) is provided. In order to provide simple constructional conditions it is proposed that the control device (7) which is connected to transducer (10) for the motor load reverses the direction of rotation of the electric motor (4) depending on the determined variable and/or change of the motor load and cuts off the same after a thus caused reverse rotation.
