A drive apparatus for a crane, and a crane. The drive apparatus comprises an engine (1) with a cylinder deactivation function, a first transmission mechanism, a transfer case (5), a second transmission mechanism, and a third transmission mechanism. One end of the first transmission mechanism is connected to the engine (1), and the other end is connected to an input shaft of the transfer case (5); one end of the second transmission mechanism is connected to an output shaft of the transfer case (5), and the other end is adapted to be connected to a loading execution mechanism of the crane; one end of the third transmission mechanism is connected to the other output shaft of the transfer case (5), and the other end is connected to an unloading execution mechanism of the crane. Because the need for power in the loading operation is small, some of cylinders of the engine may be stopped by the cylinder deactivation function of the engine, the work and the output power of the engine are reduced, and fuel consumption is decreased. Moreover, by using a single-engine transmission system, arrangement of a loading space is optimized and the weight is reduced.
