ELEVATOR BRAKING APPARATUS WITH A REPEATED BRAKING STRUCTURE CAPABLE OF PREVENTING NEGLIGENT ACCIDENTS FROM OCCURRING

摘要

PURPOSE: An elevator braking apparatus with a repeated braking structure is provided to stop the operation of an elevator by repeatedly controlling a transmission gear.;CONSTITUTION: An elevator braking apparatus with a repeated braking structure includes a transmission gear(20), a sensor(30), and a controlling part(40). The transmission gear vertically moves an elevator according to operational instructions. The sensor outputs signals by detecting the movement of the elevator. The controlling part receives the signals from the sensor and the operational instructions and stops the elevator if the signals from the sensor are received without an operational instruction.;COPYRIGHT KIPO 2013;[Reference numerals] (20) Transmission gear; (30) Sensor; (40) Controlling part; (41) Inverter; (AA) Elevator
