A lift drive (20) serves to drive and to detain a lift car, and it essentially contains a traction wheel (22) for transmitting a driving or detaining force to the lift car, a motor (21) for driving the traction wheel (22), and a braking arrangement for detaining the traction wheel (22). A drive shaft (2) connects the traction wheel, the motor and the braking arrangement to one another. The braking arrangement contains at least two braking devices (24.1, 24.2), wherein, according to the invention, the traction wheel (22) is arranged between the braking devices (24.1, 24.2). This is advantageous, since the braking torques (M
