The invention provides a crane anti-collision main beam which comprises a crane body, a lifting main beam is arranged on one side of the crane body, a hydraulic telescopic rod is arranged at the bottom of the lifting main beam, a protection assembly is arranged on the surface of the hydraulic telescopic rod and comprises two protection sleeves, and fixing pieces are arranged on the two sides of the two protection sleeves. The multiple buffering assemblies are sequentially arranged on the surface of the protective sleeve from left to right, the connecting assembly is arranged at one end of the hydraulic telescopic rod, and the multiple anti-collision assemblies are arranged on the surface of the protective sleeve. According to the anti-collision main beam for the crane, the two protective sleeves are arranged on the surface of the hydraulic telescopic rod, so that the whole outer rod of the hydraulic telescopic rod can be protected, damage and deformation caused by collision with external objects are prevented, the fixing pieces are arranged on the two sides of the protective sleeves, and the protective sleeves can be fixed to the surface of the hydraulic telescopic rod; and the protective sleeve is prevented from loosening when the hydraulic telescopic rod works.

    本发明提供一种起重机用防撞主梁,包括:起重机主体,起重机主体的一侧设置有升降主梁,升降主梁的底部设置有液压伸缩杆,防护组件设置于液压伸缩杆的表面,防护组件包括两个防护套,两个防护套的两侧均设置有固定件,多个所缓冲组件分别从左至右依次设置于防护套的表面,连接组件设置于液压伸缩杆的一端,多个防撞组件分别设置于防护套的表面。本发明提供的一种起重机用防撞主梁,在液压伸缩杆的表面设置两个防护套能对液压伸缩杆的外杆整体起到保护的作用,防止与外界的物体出现碰撞造成损坏和变形,在防护套的两侧设置固定件可以将防护套固定在液压伸缩杆的表面,防止液压伸缩杆工作时防护套出现松动。
