The invention discloses a swing supporting leg of a crane and the crane, and relates to the technical field of cranes, the swing supporting leg of the crane comprises a supporting leg body and a buffer device arranged on the supporting leg body, the buffer device comprises a collision block and a buffer block, and the two sides of the collision block in the first direction are a connecting side and a buffer side respectively; the connecting side is connected to the supporting leg body, the buffering side is used for abutting against a crane body when the swinging supporting leg swings in the first direction, a buffering groove extending in the first direction is formed in the collision block, and a groove opening and a groove bottom are formed in the two ends, in the first direction, of the buffering groove correspondingly; the buffer block is accommodated in the buffer groove, and the buffer block can move in the buffer groove. The buffering device is mounted on the swinging supporting leg of the crane, and the buffering device absorbs and disperses impact force generated when the swinging supporting leg abuts against the crane body through movement of the buffering block, so that direct impact of the swinging supporting leg on the crane body is effectively reduced, and springback of the swinging supporting leg is avoided.

    本发明公开了一种起重机的摆动支腿和起重机,涉及起重机技术领域,其中,起重机的摆动支腿包括支腿本体和设置于支腿本体上的缓冲装置,缓冲装置包括碰撞块和缓冲块,碰撞块沿第一方向的两侧分别为连接侧和缓冲侧,连接侧连接于支腿本体,缓冲侧用于在摆动支腿沿第一方向摆动时与起重机的机身抵接,碰撞块内开设有沿第一方向延伸的缓冲槽,缓冲槽沿第一方向的两端分别形成槽口和槽底;缓冲块收容于缓冲槽内,且缓冲块能在缓冲槽内移动。本发明通过在起重机的摆动支腿上安装缓冲装置,缓冲装置通过缓冲块的移动吸收和分散摆动支腿与起重机机身抵接时产生的冲击力,有效减少摆动支腿对机身的直接冲击,避免摆动支腿回弹。
