The invention provides a crane side pulling-up mechanism and a crane, and relates to the technical field of engineering machinery. The side pulling-up mechanism comprises a rack, a walking mechanism,a cargo boom, a side supporting arm, a first supporting device and a second supporting device; the side supporting arm is provided with a first end and a second end which are opposite, the first end is used for being installed on the side of the crane; and the first supporting device is detachably connected between the first end and the second end, the second supporting device is installed at thesecond end, the first supporting device and the second supporting device are both used for supporting the side supporting arm, and the first supporting device can ascend and descend and is used for adjusting the horizontal height of the second end. According to the crane side pulling-up mechanism and the crane, during arm lifting, the first supporting device serves as a main support, the second supporting device serves as an auxiliary support, and the first supporting device and the second supporting device support the side supporting arm, so that deformation of the side supporting arm can beprevented, the side supporting arm and the second supporting device can reach the preset supporting height, and side tilting of a machine body is avoided.
本发明提供了一种起重机侧扳起机构和起重机,涉及工程机械技术领域;侧扳起机构包括机架、行走机构、起重臂、侧支撑臂、第一支撑装置和第二支撑装置;侧支撑臂具有相对的第一端和第二端,第一端用于安装于起重机的侧向;第一支撑装置可拆卸的连接在第一端和第二端之间,第二支撑装置安装在第二端,第一支撑装置和第二支撑装置均用于支撑侧支撑臂,第一支撑装置可升降,用于调节第二端的水平高度。本发明在起臂时通过第一支撑装置作为主支撑,第二支撑装置作为辅助支撑,两者对侧支撑臂进行支撑,不仅能够防止侧支撑臂变形,而且能够使得侧支撑臂和第二支撑装置能够达到预设的支撑高度,避免出现机体侧倾。
