The embodiment of the invention provides a positioning system for a tower crane and the tower crane, and belongs to the field of engineering machinery. The tower crane comprises a working mechanism and a motor, the motor is used for driving the working mechanism to act, the positioning system comprises an incremental encoder, a frequency converter and a controller, and the incremental encoder is arranged on the motor and used for sending out AB-phase pulse signals and Z-phase pulse signals related to motor movement; the frequency converter is used for driving the motor to work and collecting an AB-phase pulse signal and a Z-phase pulse signal, and the frequency converter is configured to obtain the AB-phase pulse signal and the Z-phase pulse signal; calibrating the number of the AB-phase pulse signals according to the AB-phase pulse signals and the Z-phase pulse signals to obtain the calibrated AB-phase pulse number; the calibrated AB phase pulse number is sent to a controller; the controller is electrically connected with the frequency converter, and the controller is configured to receive the calibrated AB phase pulse number; and the current operation position of the working mechanism is determined according to the calibrated AB-phase pulse number. According to the invention, hardware cost can be reduced.
