The invention relates to a power drive unit and a crane; the power drive unit comprises an engine (1), a first transfer case (4), at least one second transfer case (5), and at least five drive axles; the engine (1) is in power connection with an input end of the first transfer case (4); two output ends of the first transfer case (4) are respectively in power connection with the five drive axles through the at least one second transfer case (5). The power drive unit and the crane can fully express the engine torque so as to increase whole drive force, thus enhancing the crane climbing capability; in addition, multi-axle drive can improve crane adaptation capability on a complex road; when the road is large in fluctuation and wheels corresponding to the drive axles suspend, the remaining drive axles can still provide enough drive force and wheel clunging force, thus ensuring whole vehicle driving safety, and effectively improving crane heavy duty transition efficiency.
