This utility model discloses a lifting device for PT connecting sleeves, relating to the field of installation equipment technology. The lifting device for PT connecting sleeves includes a base and a hanger located in the middle of the top surface of the base. It also includes a slider slidably connected to the top left side of the hanger, with a fixing mechanism fixedly connected to the bottom of the slider. Through the fixing mechanism, when the device is to be used, the external PT connecting sleeve is first passed through a suspension rope, and then secured using the rope loops and fixing buckles inside the suspension rope. Next, the lifting hydraulic rod is raised, allowing the sleeve to rise with the fixing plate for further transportation. This facilitates the securing and lifting of the connecting sleeve during transportation, preventing tilting and detachment during transport due to inadequate or insufficient securing, which reduces transportation efficiency and increases the damage rate of the connecting sleeve.
