US Patent 8132650 System for safe descent of people or cargoes

A device for the safe descent of people or cargo along the cable, for example, for the salvation of people in case of fire in high-rise building. To provide the salvation of a few people during the same rescue operation, the device ensures movement along the cable in both directions, downwards and upwards. There is no need for any extensive preparation before using the device. The cable, with or without a handing device, is fixed in the point of lowering, dropped downwards with the weight and then is reeled three times upon the contact disk. Such connection ensures moving the contact disk along the cable without sliding.
