Abstract: An elevator counterweight assembly (11) includes a counterweight structure (38), at least one safety brake (12a, 12b) mounted on the counterweight structure (38), and a safety actuation mechanism (16) including a connection (17) for a suspension member (18). The safety actuation mechanism (16) is configured to move, relative to the counterweight structure (38), between a normal position, and a safety position. In the safety position the safety actuation mechanism (16) is arranged to actuate the at least one safety brake (12a, 12b) and thereby brake the counterweight structure (38). The counterweight assembly (11) also includes a mechanical actuator (22), configured, when actuated, to apply a force to the safety actuation mechanism (16) and thereby move the safety actuation mechanism (16) from the normal position to the safety position, e.g. for the purposes of a handover test.

Abstract: An elevator system control system is provided and includes a sensor system configured to sense elevator car conditions, a safety system signaling element to generate a safety signal indicative of an incident and a control system configured to react to the safety system signal. When the control system receives the safety signal indicating that an incident has occurred that requires engagement of at least one of primary and secondary brakes, the control system controls a deceleration rate during the incident by operating the primary brake, determining whether the deceleration rate is within a target range and adjusting the deceleration rate based on signals from the sensor system.

Abstract: An elevator car has one or more sidewalls (4a, 4b) defining an interior space (2) for accommodating passengers; a roof (3) including a support frame (8) and a working platform (12) which is suspendably connected to the support frame (8). The working platform moves between a stowed position, above the interior space, and an operational position, within the interior space. The elevator car also includes a blocking member (20, 21), located at the support frame (8), and arranged to move between an unblocking position and a blocking position. When the blocking member (20, 21) is in the blocking position, the blocking member is configured to prevent the working platform (12) from being moved into the stowed position.
