Abstract: Disclosed is an emergency stop device with an attached hand brake system. The emergency stop device with the attached hand brake system comprises: brake units which are equipped on both sides of a car and control the movements of the car by selectively interfering with guide rails; an operation unit which is connected with the brake units and manually grants braking power to the braking units; and an interlocking unit which interlocks the brake units.

Abstract: Disclosed are an apparatus and method for testing braking performance. The apparatus of the disclosed invention comprises: a driving unit which generates power; a test unit driven by the driving unit; and a control unit which controls the operation of a braking apparatus to generate a brake force on the test unit and to check braking performance. The present invention uses a rope unit moving at a speed for inducing a braking operation by the rotation of driving sheaves spaced apart from each other, rather than testing braking performance in an expensive elevator test tower, thereby preventing the possible dangers of tests conducted in said test tower. Further, the present invention controls loading capacity simply by controlling the loads of the driving unit to enable easy testing.
