The movable small crane comprises a supporting column, a threaded rod is rotatably installed on the inner wall of the supporting column, a driving device used for driving the threaded rod to rotate is installed on the inner wall of the supporting column, and a first limiting groove is formed in the inner wall of the supporting column; a plurality of first fixing rods are installed on the inner wall of the first limiting groove, a cylindrical block is slidably installed on the outer wall of each first fixing rod, a plurality of arc-shaped blocks are fixedly installed at the bottom of each cylindrical block, and a supporting seat is fixedly installed at the bottom of the supporting column. The motor is started to enable the arc-shaped block to penetrate through the supporting base to extrude the pressing plate, the pressing plate moves downwards to enable the idler wheels to support the crane, the long front supporting legs are folded, the small crane can move conveniently, and the situation that the idler wheels of the small crane are prone to being damaged when bearing large pressure during working is avoided.

    本发明公开了一种船舶用可移动小吊机,包括支撑柱,所述支撑柱的内壁转动安装有螺纹杆,所述支撑柱的内壁安装有用于驱动螺纹杆转动的驱动装置,所述支撑柱的内壁开设有一号限位槽,所述一号限位槽的内壁安装有若干个一号固定杆,所述一号固定杆的外壁滑动安装有圆柱块,所述圆柱块的底部固定安装有若干个弧形块,所述支撑柱的底部固定安装有支撑座。通过启动电机使得弧形块穿过支撑座对压板进行挤压,压板向下移动使得滚轮对吊机进行支撑,较长的前支撑脚被折叠,便于小吊机的移动,避免了工作时小吊机的滚轮承受压力较大容易损坏的情况。
