The invention discloses a tower crane and a driving and braking integrated device thereof. The driving and braking integrated device comprises a coiling drum, a coiling cylinder supporting base, a driving motor, a planetary reducer and a braking device integrated into the coiling drum. The planetary reducer is contained into an inner cavity of a central cylinder of the coiling drum; and the braking device comprises a cylindrical shell, a friction plate assembly for locking a wheel axle, a hydraulic module and an oil pipe. A first end of the cylindrical shell is fixedly connected with a body ofthe driving motor; a second end of the cylindrical shell is connected with a first planet carrier through a second bearing; the second end partially stretches into the inner cavity of the central cylinder of the coiling drum; and the wheel axle and the driving shaft penetrate into the cylindrical shell. Due to the integrated design that the braking device is partially integrated and designed intothe planetary reducer and the planetary reducer is integrated into the coiling drum, a lifting mechanism of the tower crane is more compact, lower in mass and smaller in size.
