PCT No. PCT/SE90/00206 Sec. 371 Date Oct. 9, 1991 Sec. 102(e) Date Oct. 9, 1991 PCT Filed Mar. 30, 1990 PCT Pub. No. WO90/12222 PCT Pub. Date Oct. 18, 1990.A driving device in particular for sawing machines comprises two hydraulically rotatable members (23, 24), which are rotationally connected to each other and one of which is adapted to transmit driving power to a shaft (4). The second rotatable member (24) is connected to a first gear (25) so as to be secured against relative rotation thereto, said first gear being in driving force transmitting relation to a second gear (26), which likewise is arranged to transmit driving power to the shaft. Means (27) are provided to make the device operate in either one of at least two operational states, in a first of which the first member (23) drives the shaft in rotation whereas the second gear (26) and the shaft are free to rotate relative to each other and in a second of which the second gear (26) drives the shaft in rotation whereas the first member (23) and the shaft are free to rotate relative to each other.
