The invention relates to a four-guide-column type lifting machine. A bidirectional output shaft motor and four transmission cases are fixed to a base. The transmission cases are provided with screw input shafts. A guide sleeve is fixed to each transmission case. Guide columns are arranged in the guide sleeves in a sliding manner. External threads are machined at the bottom ends of the guide columns. The bottom ends of the guide columns are matched with the screw input shafts of the transmission cases through the threads. The centers of the four transmission cases are located at four peaks of the same rectangle. The bidirectional output shaft motor is located at the center position of the rectangle where the four transmission cases are located. First couplers are fixed to two output shafts of the bidirectional output shaft motor, and the other ends of the first couplers are connected with input shafts of commutators. Second couplers are fixed to output shafts of the commutators, and the other ends of the second couplers are connected with the screw input shafts of the transmission cases. The four-guide-column type lifting machine is of a pure mechanical structure and is simple and reliable in structure, and synchronous lifting and stable running are achieved.
