The invention relates to brake rope drop resisting device. The invention uses a buffer made up of drum, shaft sleeve, bearing, shaft, friction plate, external brake plate, internal brake plate, rope pressing block, force regulating plate, force regulating nut, disc spring, and connector made up of three pairs of wedges, wedge back, rolling bar, clamping board, clip. The buffer rope on the buffer is connected to the brake rope through the connector, the capturing mechanism on the elevating container is driven with pressure spring with adjustable pressure, the connector uses wedge self locking mechanism with rolling friction to clamp the buffer rope and brake rope, the capturing mechanism uses the wedge self locking theory to capture the brake rope, the brake force is stable and easy to be regulated. The structure is simple, convenient, and light.
