The invention discloses a lifting device and method of a tower-shaped mast. A horizontal shaft is arranged on a mast base frame and is hinged to the lower part of the mast; a mast motor arranged on the mast is meshed with a deceleration gear through a driving gear and an intermediate gear; a fixed gear which is coaxial with the horizontal shaft is arranged on the mast base frame; the deceleration gear is meshed with the fixed gear; a balancing weight is arranged at the tail end part of the mast, under the horizontal shaft; a swinging barrier detector is arranged at the top of the mast. The lifting device of the tower-shaped mast further comprises a control device and an alarm device, wherein the control device is connected with the mast motor, the barrier detector and the alarm device. The lifting device effectively solves the problem that a mast lifting device in the prior art can easily cause collision accidents due to neglect or wrong judgment. The lifting device of the tower-shaped mast, disclosed by the invention, can automatically detect barriers and automatically put down the mast, so that the sailing safety can be guaranteed; therefore, the lifting device has a high practical value.
