The invention belongs to the field of lifting appliances, particularly relates to an anti-swing lifting appliance for a crane, and aims to solve the problems that when an existing crane lifting appliance vertically lifts or moves forwards, backwards, leftwards and rightwards, a lifted object cannot be conveniently prevented from swinging, so that the lifting appliance is easy to shake and collide in the lifting process, and the operation risk is relatively high. A U-shaped plate is fixedly mounted at the bottom of the cross beam through welding, a first empty groove and a second empty groove are formed in the cross beam, two symmetrical first mounting grooves are formed in the cross beam, a first through hole is formed in the inner wall of one side of the first empty groove, the first through hole communicates with the two first mounting grooves and the second empty groove, and a rotating rod is rotatably mounted in the first through hole; in the using process, a lifted object can be conveniently prevented from swinging, so that shaking and collision during vertical lifting or front-back and left-right movement can be avoided, the operation risk is effectively reduced, the structure is simple, and using is convenient.
本发明属于吊具领域,尤其是一种起重机用防摆吊具,针对现有的起重机吊具在垂直提升或前后左右移动时,不便于对起重物品进行防摆,从而导致在吊装过程中容易发生晃动碰撞,操作风险性较高的问题,现提出如下方案,其包括横梁,所述横梁的底部通过焊接固定安装有U型板,横梁内开设有第一空槽和第二空槽,横梁上开设有对称的两个第一安装槽,第一空槽的一侧内壁开设有第一通孔,第一通孔与两个第一安装槽和第二空槽相通,第一通孔内转动安装有转杆,本发明能够在使用过程中,便于对起重物品进行防摆,从而可以避免在垂直提升或前后左右移动时发生晃动碰撞,有效降低了操作风险性,结构简单,使用方便。
