  • Publication number: 20210395044
    Abstract: The present disclosure relates to an elevator having a function of removing dust adhered to an object aboard, including: a car which provides a boarding space, and in which a pair of air holes disposed in a diagonal direction each other at a same height of an inner space are formed; and a pair of fan modules that generates whirlwind rotating in the inner space of the car by ejecting air traveling from one of the pair of air hoes in a direction away from a center of the inner space of the car and ejecting air traveling from the other of the pair of air hoes in a direction away from the center of the inner space of the car, in which dust adhered to the object aboard inside the car is separated from the object aboard by the whirlwind generated inside the car.

  • Patent number: 9446930
    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.

  • 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.
