摘　　要：根据武汉天兴洲公铁两用长江大桥主桥斜拉桥为双塔三索面三主桁的结构特点,JQJ700架梁起重机用三吊点起吊模式。具体介绍了架梁起重机的吊具纵、横移机构,整机纵移机构,吊具调平机构,起升机构,前支顶、后锚固及电气控制系统的设计特点。In the light of the structural of Wuhan Tianxingzhou Changjiang River three cable planes and three main trusses, feature that the cable-stayed bridge of the main bridge Rail-cum-Road Bridge is composed of double pylons, the JQJ700 Girder Erection Crane for construction of the main bridge is designed to work in a way of three-point hoisting. This paper describes in specific details the design characteristics of the longitudinal and transverse traveling mechanisms of hoisting riggings of the Crane, the longitudinal traveling mechanism of the whole Carne, the leveling mechanism of the riggings, the hoisting mechanism and also the front support, rear anchorage and electric control system of the Crane.
