The invention discloses a swing arm type underslung crane. The underslung crane comprises a cross beam, wherein a sliding seat is in clearance fit with the bottom of the cross beam, a balancing weightis arranged below the left side of a swing arm, an electric hoist is fixedly connected to the right side of the bottom of the swing arm, and a transmission assembly is arranged below the sliding seat. According to the swing arm type underslung crane, through threaded connection between a screw and the sliding seat and meshing connection between a driving wheel and driven wheels above, the slidingseat can drive the swing arm to transversely slide and axially rotate simultaneously, so that the hoisting range is expanded, and the use practicability and convenience are improved; the swing arm can transversely slide in a sleeve, then the swing arm is transversely prolonged, the application range is further expanded, and the use applicability is improved; and through clearance fit between a short rod and a rotating rod and corresponding arrangement of the rotating rod and the two driven wheels, the rotating rod can clamp the two driven wheels, then the swing orientation and the telescopinglength are limited, and the use stability and precision are further improved.

    本发明公开了一种摆臂式悬挂起重机,包括横梁,所述横梁的底部间隙配合有滑座,所述摆臂的左侧下方设有配重块,所述摆臂的底部右侧固接有电动葫芦,所述滑座的下方设有传动组件。该摆臂式悬挂起重机,可通过螺杆与滑座的螺纹连接,以及主动轮与上方从动轮的啮合连接,使得滑座可带动摆臂横向滑动的同时,可使其轴向转动,进而扩大起重范围,提升使用实用性和便捷性,使得摆壁可在套筒内横向滑动,进而对摆臂起到横向延长的作用,进一步扩大使用范围,提升使用适用性,可通过短杆与转杆的间隙配合,以及转杆与两个从动轮的对应设置,使得转杆可对两个从动轮卡接,进而对摆动的指向和伸缩长度起到限制作用,进一步提升使用稳定性和精度。
