    摘要： Apparatus for restricting motion of an elevator car includes bars or other stiff, elongated members, which are extended outwardly from opposing ends of the elevator car, when the car is positioned in a specified zone of vertical displacement, above the lower edge thereof The displacement zone may be on the order of twelve inches. An elevator control, such as an inspection bank mounted on top of the elevator car, is then operated to move the elevator car slightly downward, to the lower edge of the displacement zone, whereupon the elongated members are brought into solid contact with respective complementary supporting members, joined to opposing elevator guide rails. As the elongated members are extended, a switching arrangement, electrically coupled to the control, is simultaneously actuated to prevent movement of the elevator car above the displacement zone while the elongated members are in their extended mode.

    摘要： According to an aspect, there is provided an elevator car parking brake comprising brake pads and an actuator configured to move the brake pads with respect to a guide rail. The elevator car parking brake further comprises levers, each having an associated brake pad; and at least one screw associated with the actuator and rotatably fixed to at least one lever via at least one attaching member. In a braking operation, the actuator is configured to rotate the at least one screw in a first direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move towards the guide rail. In a brake release operation, the actuator is configured to rotate the at least one screw in a second direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move away from the guide rail.
