The invention relates to a lifter, in particular to a visualized self-leveling double-column type lifter. The visualized self-leveling double-column type lifter comprises two hydraulic units, two stand columns and two sliding tables, and is characterized in that each sliding table is connected with a sensor and a lifting arm, and each sense transmits a detected sliding table position signal to the corresponding controller; the controllers compare the sliding table position signals of the sensors corresponding to the two sliding tables, determine whether the sliding table position signals are consistent or not and then determine whether leveling signals are sent out by the controllers to control solenoid valves of the hydraulic units to be opened or closed. The visualized self-leveling double-column type lifter has the advantages that steel wire rope adjustment synchronization is replaced by two air cylinder synchronization through feedback automatic adjustment, so troublesome installation and maintenance processes are avoided; due to two control boxes and the two hydraulic units, a quick lifting effect can be achieved; the lifter is convenient and quick to install; the stand columns can be installed in a symmetric mode or in the manner of inclining by 30 degrees, the lifting arms can be placed horizontally, and two-segment type structures of the lifting arms can be placed in parallel; due to visualized operation, an operator can be safer.
