Abstract
A method for preventing an inadmissibly high speed of a load receiving unit of an elevator, including the steps of supplying information about an actual position and an actual speed of the load receiving unit in an area of an entire travel way of the load receiving unit to a speed monitoring device by at least one measuring system, continuously comparing the actual speed with a speed limit value by the speed monitoring device, and activating braking measures if the speed of the load receiving unit exceeds a speed limit value. At least three different braking measures are successively triggered by the speed monitoring device.
