An elevator including an elevator shaft defined by top and bottom end terminals; an elevator car vertically movable in the elevator shaft; an elevator hoisting machinery drives the elevator car; an electromechanical braking apparatus that brakes movement of the elevator car; a first measuring device that provides first position data and first speed data of the elevator car; a second measuring device that provides at least second position data of the elevator car; and a safety monitoring unit communicatively connected to the first and second measuring devices and that determines a synchronized position of the elevator car from the first and second position data, and determines an elevator car slowdown failure in proximity of the top or bottom end terminals from the first speed data and the synchronized position. The safety monitoring unit causes braking of the elevator car with the electromechanical braking apparatus upon determination of slowdown failure.
