The invention concerns a drive arrangement of a lifting gear and/or a traveling gear, with a pole-reversible rotary-current motor with windings for at least two different actuating speeds, with a pole switching element connecting the rotary-current motor to a voltage supply for changing between the actuating speeds of the rotary-current motor. In order to create a drive arrangement of a lifting gear and/or a traveling gear with a rotary-current motor, whose switching behavior is optimized in relation to the actuation of the rotary-current motor, it is proposed that a power switching element (3) be hooked up in front of the pole switching element (5), and it can be separated from the voltage supply via the power switching element (3) for the pole switching process of the rotary-current motor (2).
