Elevator car-mounted governor system

摘要: An elevator car speed governor is mounted on the top of assembly (2), and measures by contacting a fixed element (6) in hoistway. The can be taut cable extending from hoistway to pit, or one guide rails, for example. has centrifugally operated connection (16,18) with emergency brakes (22) car. When overspeed detected, actuated cause engage rails stop operate at relatively low rates, used systems which do not have an overhead machine room, such as hydraulic linear induction motor elevators.
