The invention discloses a light multifunctional crane with seven telescopic arms. The light multifunctional crane comprises a supporting seat, a fixed frame is assembled on the upper side of the outer side wall of the supporting sea in a hinged mode, a telescopic arm frame is fixedly installed on the inner side wall of the fixed frame, suspension arms are sequentially assembled on the inner side wall of the telescopic arm frame in an inserting mode, supporting frames are fixedly installed at the right ends of the suspension arms, and stretchable oil cylinders are fixedly mounted on the outer side walls of connecting blocks. According to the light multifunctional crane with the seven telescopic arms, the size of the designed supporting seat is small, the installation area of the crane is small, meanwhile, the seven telescopic arms are arranged, and therefore the retracting length of the crane is short, the working amplitude can reach 10 m, the working amplitude is large, and the speed of the suspension arms during stretching and retracting can be increased through the six sets of stretchable oil cylinders; and in addition, the stretchable oil cylinders are arranged on the outer side of the telescopic arm frame, so that the stability of the suspension arms is effectively guaranteed, fault judgment and maintenance are facilitated, and the light crane is small in occupied space, flexible, easy to operate, convenient to carry by a truck and an oversize vehicle and wide in application range.

    本发明公开了一种具有七节伸缩臂的轻型多功能起重机,包括支座,支座的外侧壁上侧铰接装配有固定框,固定框的内侧壁固定安装有伸缩臂架,伸缩臂架的内侧壁依次插接装配有吊臂,吊臂的右端均固定安装有支撑架,连接块的外侧壁均固定安装有伸缩油缸,本发明设计的支座体积较小,进而令此装置的安装面积很小,同时设置了七节伸缩臂,令其收回长度较短的同时,工作幅度能够达到10米,作业幅度大,且通过六组伸缩油缸,能够提升吊臂伸缩时的速度,此外,将伸缩油缸设置在伸缩臂架的外侧,在有效保证吊臂的稳定性的同时,便于判断故障和维修,令此轻型起重机占用空间小、灵活、操作简单,且便于卡车、大型车携带,适用范围广。
