The invention belongs to the field of crane devices, and particularly relates to a crane stand column convenient to lift. The crane stand column comprises a chassis, a stand column and a cargo boom, the top of the chassis is fixedly connected with the stand column, and the top position of the crane stand column is rotationally connected with the cargo boom; the bottom surface of the cargo boom is connected with a sliding block in a sliding manner, a winding barrel is rotationally connected in the sliding block, and a steel cable is wound on the surface of the winding barrel; the bottom surface of the steel cable is fixedly connected with a hook, a protection seat is arranged at the periphery of the chassis, the top surface of the protection seat is fixedly connected with a protection sleeve, and the surface of the cargo boom is wrapped with a heat preservation sleeve. According to the present invention, the stand column can be protected through the protection sleeve, meanwhile, the protection sleeve is matched with the heat preservation sleeve, the key bearing components, such as the stand column, the cargo boom, etc., can be sealed and protected, and the external air is isolated; the problem that under the winter condition, the stand column and the cargo boom are directly placed in a low-temperature environment, and then the strength of the stand column and the cargo boom is affected, is solved; and the efficient lifting work of a crane in winter is facilitated.
