The invention discloses a work platform capable of ascending and descending. The work platform capable of ascending and descending comprises a work table, a base, an ascending and descending device and a transmission device, wherein the ascending and descending device is fixedly arranged in the base, a storage drawer is built in the work table, the work table is fixedly arranged on the top of the ascending and descending device and comprises two speed reducers arranged at the two sides of the bottom surface of the work table, each speed reducer is provided with a lead screw capable of vertically ascending and descending, each lead screw is connected with the work table, a balancing shaft is connected between the two speed reducers, the transmission device comprises a motor and a motor base, a belt wheel is arranged between the motor and the balancing shaft for synchronous transmission, so that the lead screws of the speed reducers drive the work table to simultaneously ascend and descend. The work platform has the advantages that the surface of the work platform can fast and effectively ascend and descend to a proper height according to the requirements of operators, the work efficiency is effectively improved, and the fatigue degree in movable joint aspects of the lumbar vertebra, the cervical vertebra and the like of the operators can be reduced.
