The invention discloses a double-beam cantilever crane. The double-beam cantilever crane comprises a frame and a first swing arm which is arranged on the frame in a swinging manner, wherein a push-pull structure which is connected with the first swing arm and is used for driving the first swing arm to swing and lift is horizontally arranged on the frame; a power assembly which is connected with the push-pull structure is arranged below the frame; a second swing arm is movably arranged on the first swing arm in parallel; a hook which is used for connecting with a heavy object is movably arranged at the end of the second swing arm; the frame moves to drive the whole crane to move along with the frame; the power assembly works to drive the push-pull structure to act; the push-pull structure drives the first swing arm to swing and lift; when the first swing arm swings and lifts, the second swing arm is driven to swing and lift along with the first swing arm; the power assembly also drivesa transmission mechanism to drive a winding structure to act; the winding structure drives the second swing arm to slide in parallel along the first swing arm, so that the lifting height is further increased; and the double-beam cantilever crane can stretch and retract to lift while swinging and lifting, so that a double-beam lifting function is realized, and the lifting height is higher.

    本发明公开了一种双梁悬臂起重机,包括车架和摆动安装在所述车架上的第一摆臂,在车架上水平安装有连接所述第一摆臂用于驱动第一摆臂摆动升降的推拉结构,在车架的下方设置有连接所述推拉结构的动力组件;在第一摆臂上平行活动设置有第二摆臂,在所述第二摆臂的端头活动安装有用于同重物连接的挂钩;通过车架移动带动整个起重机跟随移动,利用动力组件工作驱动推拉结构动作,由推拉结构驱动第一摆臂摆动升降,在第一摆臂摆动升降时带动第二摆臂跟随摆动升降,且动力组件还带动传动机构驱动缠绕结构动作,缠绕结构驱动第二摆臂沿着第一摆臂平行滑动,从而进一步增加升降高度,在摆动升降的同时还伸缩升降,实现双梁起重功能,起重高度更高。
