2121496 9307994 PCTABS00021 A method and apparatus (20) therefor is provided to enable a single operator to effect a controlled release of an elevator hoist brake (32) thus allowing "drifting" of the elevator car to the nearest floor and quick safe rescue of trapped passengers during an electrical outage. An observer having the elevator car in view may communicate (e.g. by hand held transceiver) desired car movements to the operator who is typically located in the machine room atop the elevator shaft. This method improves the overall response time for all emergency elevator rescues by reducing time consuming and dangerous hatch location rescues to mostly simple rescues, especially in blackouts and earthquakes. |
