摘要： An elevator assembly (1) comprises an elevator car (2), a counterweight (4), and a safety device (8) located on a roof (9) of the elevator car (2). A locking handle (10) is positioned within the elevator shaft (6), and connected to a first end (12a) of a tension member (12). A blocking stop (14) is connected to a second end (12b) of the tension member (12). The blocking stop (14) is moveable between an inactive state, in which the tension member (12) holds the blocking stop (14) in a position in which it does not limit downwards movement of the counterweight (4), and an active state, in which tension in the tension member (12) is reduced to allow the blocking stop (14) to move to a position in which it limits downwards movement of the counterweight (4).
