  • Patent number: 8429959
    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.
