摘要:
In an elevator apparatus, a brake control device has a first brake control portion, a second brake control portion, and a third brake control portion. The first brake control portion operates a hoisting machine brake to stop a ascending/descending body as an emergency measure when an abnormality is detected. The second brake control portion reduces a braking force of the hoisting machine brake when a deceleration of the ascending/descending body becomes equal to or higher than a predetermined value during an emergency braking operation of the hoisting machine brake. The third brake control portion monitors a slip speed of a main rope with respect to a drive sheave during emergency braking operation of the hoisting machine brake, and reduces a braking force of the hoisting machine brake when the slip speed of the main rope becomes equal to or higher than a predetermined value.
