A movable hydraulic brake lifter is characterized in that a high-pressure oil pump is driven by a power supply and a hydraulic output of the high-pressure oil pump reaches a distributor through an overflow valve and is connected with a hydraulic motor which is arranged on a headstock gear through a high-pressure oil pipe. The hydraulic motor is connected with the headstock gear by a joint slack or a concentric chuck. The utility model has the advantages of no need of manual start and shut down, reducing the labor intensity and improving the start and shut down speed, which solves the rust and damage problem of the headstock gear lead-screw for a long time stop and saves a plurality of construction fund and managing expenses by not setting up the power supply and an electrical instrument in less important brake or even a small junction and not setting up a daily manual management. The utility model is a movable machine which means not each brake needs to be equipped.
