  • Publication number: 20150014097
    Abstract: A descending escape equipment comprises a descending device and a decelerating device. The descending device includes a shaft member which is wound around by two rope members in directions opposite to each other, so that while the shaft member is rotated to release one of the rope members, the other one of the rope members is retracted by the shaft member. The decelerating device includes a transmission member connected between the shaft member and the generator, and the shaft is being rotated to drive, via the transmission member, the generator that is loaded with the generator load for reducing a releasing speed and a retracting speed by a resistant moment of the generator generated by the generator load.

  • Publication number: 20140097285
    Abstract: A climbing assisting equipment includes a rope transmitting device and a slow-descending device. The rope transmitting device includes a rope member and a rope reeling member. The slow-descending device has a transmission member connected between the rope reel member and a generator. When the rope member is pulled down, the generator is driven by the rope reel member via the transmission means to generate electrical power to a generator load, and to thus reduce a descending speed of the rope member by a resistant moment to the generator.
