FIELD: salvage operations.SUBSTANCE: invention refers to emergency evacuation devices used mainly for people's escapement dumping from buildings and equipped with a mechanic action braking mechanism. The saving device contains two similarly positioned slidewires with a swivelling hook, the fixation unit represented by a buckled belt and a braking mechanism. Slidewire allowances are accommodated inside the belt. The braking mechanism is positioned on the wires between the fixation unit and the swivelling hook. The braking mechanism is designed in the form of a separate body containing guiding channels and wedge-shaped braking elements and ensuring independent braking of the both slidewires. The slidewires are passed through flexible tubes between the braking mechanism and the slidewires outlet from the belt buckle.EFFECT: invention enables enhancement of the saving device reliability.11 cl, 5 dwg |
