The invention discloses a stand column folding type light crane. The stand column folding type light crane comprises a base, a stand column, a folding stand column and a first-stage suspension arm frame, the stand column is fixedly installed on the upper portion of the base, the folding stand column is hinged to the upper end of the stand column, the first-stage suspension arm frame is assembled at the upper end of the folding stand column, a first-stage oil cylinder is assembled on the left side of the stand column, the upper end of the first-stage oil cylinder is assembled in the middle of the outer wall of the folding stand column, a second-stage oil cylinder is assembled on the surface of the folding stand column, a load-bearing hinge seat is arranged at the root of the bottom face of the first-stage suspension arm frame, the upper end of the second-stage oil cylinder and the load-bearing hinge seat are hinged to each other, and a winch lifting hook is arranged at the front end of the first-stage suspension arm frame in an assembled mode. The effect of single-stage unfolding can be achieved, the length of the suspension arm frame can be controlled more flexibly, and compared with multi-stage coordinated synchronous unfolding, and single-stage stretching is more energy-saving; a stable sleeve shell assembled at the joint of the folding stand column and the first-stage suspension arm frame is beneficial to improving the connection strength between the folding stand column and the first-stage suspension arm frame; and a guide wheel is used in cooperation with a traction rope.

    本发明公开了一种立柱折叠式轻型起重机,包括基座、立柱、折叠立柱和一级吊臂架,立柱固定安装于基座的上部,折叠立柱铰接于立柱的上端,第一级吊臂架装配于折叠立柱的上端,立柱的左侧装配有一级油缸,一级油缸的上端装配于折叠立柱外壁的中部,折叠立柱的表面装配有二级油缸,一级吊臂架底面的根部设置有承重铰接座,二级油缸的上端与承重铰接座相互铰接,一级吊臂架的前端装配有卷扬吊钩,能够达到单级展开的效果,可更灵活的控制吊臂架的长度,且相较于多级协调同步展开,单级伸缩更节能。折叠立柱与一级吊臂架的连接处装配的稳定套壳有助于提高两者间的连接强度;引导轮用于配合牵引绳使用。
