Title: Emergency brake apparatus for elevator system

Abstract: An emergency brake apparatus for an elevator system is installed on an elevator cage or a balance weight of the elevator system and includes a grip member with slant surfaces and a pressing surface sandwiching a guide rail, a pressing member disposed movably between the slant surfaces of the grip member and the guide rail, and an electric solenoid connected to the pressing member and actuated by an electric signal. The electric solenoid positions the pressing member away from the guide rail in a non-braking operation while pushing the pressing member between the slant surfaces and the guide rail in a braking operation.
