摘要： A drive device of an elevator includes a frequency converter to be connected to a public AC supply network and an elevator motor. The frequency converter includes a network rectifier configured to be connected to the AC supply network, a motor bridge to be connected to the elevator motor and a DC intermediate circuit located between the network rectifier and the motor bridge. The motor bridge is controlled by a control circuit which feeds the motor bridge with control pulses to regulate the motor speed. The drive device further includes at least one drive prevention circuit connected between the control circuit and the motor bridge. The drive prevention circuit is configured to obtain a safety signal from an elevator safety circuit includes two separate safety input circuits each configured to be connected to the elevator safety circuit to receive a safety signal. Each of the safety input circuits is configured to interrupt the connection between the control circuit and the motor bridge in response to the safety signal status.

摘要： An elevator system (100) includes an elevator car (102). A first drive assembly (160) engages a first tension member (112). The first tension member (112) is coupled to the elevator car (102) and to a first counter-weight (104). A second drive assembly (170) engages a second tension member (122). The second tension member (122) is coupled to the elevator car (102) and to a second counterweight (106). The first tension member (112) can be coupled to the elevator car (102) at a first position (110) and the second tension member (122) can be coupled to the elevator car (102) at a second position (120) opposite the first position (110).

摘要： An elevator may include an elevator car, a set of hoisting ropes, a hoisting machine, a traction sheave, and a brake. The elevator car may be suspended on the hoisting ropes. The hoisting machine may drive the traction sheave to move the elevator car using the hoisting ropes. The brake may include a brake wheel and brake shoes. The brake may exert an effect on rotation of the traction sheave. During braking, the effect of the brake on the rotation of the traction sheave may depend on a direction of rotation of the traction sheave. The effect of the brake on the rotation of the traction sheave may be greater when the direction of rotation of the traction sheave during braking corresponds to the elevator car moving downward than when the direction of rotation of the traction sheave during braking corresponds to the elevator car moving upward.
摘要翻译： 电梯可以包括电梯轿厢，一组起重绳索，起重机，牵引滑轮和制动器。 电梯轿厢可悬挂在起重绳索上。 起重机可以使用提升绳索驱动牵引绳轮使电梯轿厢移动。 制动器可以包括制动轮和制动蹄。 制动器可能对牵引滑轮的旋转产生影响。 在制动期间，制动器对牵引滑轮的旋转的影响可能取决于牵引滑轮的旋转方向。 当制动期间牵引滑轮的旋转方向对应于电梯轿厢向下移动时，制动器对牵引滑轮的旋转的影响可能大于在制动期间牵引滑轮的旋转方向对应于电梯轿厢 向上移动
