In order to achieve the purpose of enabling long-term operation of the mobile unit, provided is a crane 10 which has a crane body 20 and a mobile unit 40 that moves around the crane body 20, , wherein the crane body 20 has power supply means 60, 62, 64 and has a power supply path member 51 that is connected to the mobile unit 40 and supplies power from the power supply means 60, 62, 64 to the mobile unit 40. Thus, the mobile unit 40 is not equipped with a power supply but is supplied with power from the crane body 20 side, thereby allowing the long-term operation of the mobile unit 40.
为了实现移动体的长期运行目的,本发明提供一种起重机(10),其具有起重机主体(20)及在起重机主体(20)的周围移动的移动体(40),其中,起重机主体(20)具有电力供给机构(60、62、64),所述起重机具有与移动体(40)连接并从电力供给机构(60、62、64)向移动体(40)供给电力的电力供给路部件(51)。由此,移动体(40)无需搭载电源,从起重机主体(20)侧即可接收电源供给而实现移动体(40)的长期运行。
