| (54) | Emergency braking system for an elevator |
| (57) A control device (13) stores, in correspondence with the position of a car (3), an
overspeed setting level that is set to become smaller in the vicinity of a terminal
end portion of a hoistway toward the terminal end portion. When the detected speed
of the car (3) exceeds the overspeed setting level at the position of the car as detected
by an encoder, an activation signal is outputted from the control device. Emergency
braking is applied on the car (3) as a brake device or a safety device (7) is activated
upon the input of the activation signal. The control device is electrically connected
with a display that displays the position of the car obtained based on information
from the encoder, and the value of the overspeed setting level at that position of
the car (3).
