Abstract (en)

[origin: EP1498380A1] The present invention provides an inexpensive elevator emergency braking apparatus operating to swiftly decelerate or stop a car when the car ascends at greater than or equal to a rated velocity, and not requiring special installation space. <??>The elevator emergency braking apparatus includes a braking mechanism portion mounted inside a sheave so as to be pivotable around a first shaft parallel to an axle of the sheave and so as to be positioned on a like side as a counterweight relative to a vertical line passing through the axle, and being provided with a brake shoe at an opposite end from the first shaft, the braking mechanism portion adopting a standby position in which the brake shoe is separated from an inner circumferential wall surface of an outer ring of the sheave and a braking position in which the brake shoe contacts the inner circumferential wall surface of the outer ring; and an activating mechanism portion for maintaining the braking mechanism portion in the standby position when not braking and maintaining the braking mechanism portion in the braking position when braking. <IMAGE>
